Molecular Testing on the Evidence Investigator

The Evidence Investigator is a compact, semi-automated benchtop analyser which is renowned for its versatility, robustness and effective reporting methods. The Evidence Investigator has offered efficient and comprehensive testing in a wide range of laboratory settings for many years including, clinical diagnostics, molecular, research, toxicology and food diagnostics.

The Evidence Investigator is the perfect fit for medium throughput laboratories seeking maximum use of bench space and can process up to 44 results from a single sample, with a maximum throughput of up to 2376 tests per hour.

It is extremely well equipped to provide reliable and accurate results because results are generated using Charge Coupled Device (CCD) camera, which quantifies chemiluminescent light. The light then measures the degree of binding between the sample and specific biochip bound ligands. The Evidence Investigator image processing software translates light signal generated from chemiluminescent reactions into analyte concentrations which removes the need for any manual processing of data.

Our molecular product range offers diagnostic, prognostic and predictive solutions across a variety of disease areas including sexually transmitted infection (STI), respiratory tract infection, colorectal cancer, familial hypercholesterolemia (FH) and cardiovascular disease (CVD). Additionally, we can provide a wide range of assay formats including single nucleotide polymorphisms (SNP) genotyping, pathogen detection and mutation detection. The technology allows simultaneous detection of multiple analytes from a single sample for efficient and cost-effective testing.

Pathogen Detection

STI and Respiratory Arrays

Sexually transmitted infections (STIs) affect more than 1 million people every day and each year 500 million new cases of STIs occur.1 Therefore, it is vital for early and accurate detection. Randox’s Sexually Transmitted Infections Multiplex Array simultaneously detects 10 bacterial, viral and protozoan including primary, secondary and asymptomatic co-infection for a complete infection profile. The assay is based on a combination of multiplex PCR and biochip array hybridisation. Innovative PCR priming technology permits high discrimination between multiple targets.

Respiratory tract infections are caused by many viral and bacterial pathogens and are the second most common cause of morbidity and mortality worldwide.2 The Respiratory Multiplex Array is the most comprehensive screening test for infections of both the upper and lower respiratory tracts, simultaneously detecting 22 bacterial and viral pathogens from a single sputum lavage or nasopharyngeal sample.

Both arrays detect the most common and frequently requested infections in sexual and respiratory health. These comprehensive, highly sensitive and specific tests enable identification of co-infections simultaneously, often in asymptomatic patients and enable antibiotic stewardship.

Mutation Detection

KRAS, BRAF, PIK3CA Array and Familial Hypercholesterolemia Arrays I & II

The colorectal cancer (CRC) is the third most common cancer worldwide. Overall, the lifetime risk of developing colorectal cancer is: about 1 in 22 (4.49%) for men and 1 in 24 (4.15%) for women.3 The KRAS, BRAF, PIK3CA Array simultaneously detects 20 point mutations within the KRAS, BRAF and PIK3CA genes. The assay is validated for use with the DNA extracted from fresh/frozen and formalin fixed paraffin embedded tissue. The array is CE marked for routine clinical use.

Familial Hypercholesterolemia (FH) is a genetic disorder of lipoprotein metabolism. 4It is the most common autosomal dominant, or inherited disease and affects the plasma clearance of LDL-cholesterol, resulting in premature onset of cardiovascular disease and higher mortality risk.5 Early diagnosis is crucial as by the time the FH sufferer enters early adulthood they will have accumulated >20 years of continuous exposure to build up of fatty or lipid masses in the arterial walls and are at the hundred-fold greater risk of a heart attack than other young people. The Familial Hypercholesterolemia (FH) Arrays I & II are rapid, simple and accurate detection of 40 FH-causing mutations within the LDLR ApoB and PCSK9 genes.

These unique biochip assays permit high discrimination between multiple targets in several genes with a rapid turnaround time (3 hours). The arrays enable detection of the most frequently occurring mutations known to cause disease (FH) and adversely affect patient treatment (KRAS, BRAF, PIK3CA).  A unique primer set is designed for each target which will hybridise to a complimentary oligo-nucleotide probe spotted on a biochip discrete test region (DTR).

SNP Genotyping

Cardiovascular Risk Prediction Array

Coronary Heart Disease is the leading cause of death in the developed world and its prevention is a core activity for public health systems worldwide.6 Randox have the Cardiac Risk Prediction Array which will allow for 19 SNPs to be genotyped simultaneously, which incorporate a test to identify patients predisposed to statin-induced myopathy.

This array identifies individuals with a genetic predisposition to coronary heart disease (CHD). The innovative multiplex primers are designed to discriminate DNA sequences which differ only at one base.

RCLS on National Heart Month

Randox Clinical Laboratories Service (RCLS) has been built on 35 years of Randox Laboratories experience. The aim of our RCLS team is to meet the time sensitive, custom-made requirements of research and clinical projects. They specialize in biomarker and multiplex testing to provide full laboratory services to aid the project aims and timelines whilst saving time and money. Currently, there are four laboratories across the UK located in Liverpool, London, Holywood and the Randox Science Park in Antrim where knowledgeable and proficient teams are situated and are available accordingly to provide support and guidance.

Continuing with National Heart Month, RCLS would like to take the opportunity to reinforce the importance of taking care of your hearts health. (WHO) highlighted Ischemic heart disease and stroke are the world’s biggest killers. An estimated 17 million people die of cardiovascular disease particularly heart attacks and strokes every year.1

Lipoprotein (a) which is also known as Lp(a) consists of two protein molecules, apolipoprotein (a) or apo(a). It is a large lipoprotein particle made by the liver. The Apo(a) particle is a very sticky protein particle, thought to be involved in the clotting system and its addition can be likened to adding a patch of Velcro on to a normal LDL particle. 2 Having some cholesterol and Lp(a) in your blood is normal however, high levels of LDL cholesterol would increase your risk of having some serious heart implications.

It has been highlighted in recent research that blood levels of Lp(a) could be an important indication as it is currently the strongest inherited risk factor for developing cardiovascular disease and stroke. Globally, one in five people have high levels of Lp(a) greater than 50mg 3. As a result, gradually narrow the arteries, limiting blood supply to the brain, heart kidney, legs and can also increase the risk of blood clots, heart attack and stroke.

High Lp(a) can also be related to other common risks factors of cardiovascular diseases for example, smoking, diet, diabetes, high blood pressure and lack of exercise. Therefore, it is possible that those who appear “healthy” can have high Lp(a) in their genes and still be at high risk of cardiovascular diseases.

The Lipoprotein(a) Foundation strongly emphasized that the Lp(a) test would be advised if you have the following:

  • If there is a family who has history with cardiovascular disease including stroke, heart attack, circulation problems in the legs and/or narrowing of the aorta, at a young age. If someone in your family has high Lp(a), their children have a 50/50 chance inheriting it.
  • Stroke or heart attack are classical risk factors including high LDL-cholesterol, obesity, diabetes and smoking have been eliminated
  • High levels of LDL-cholesterol following treatment with statins or other LDL lowering medications

Randox Clinical Laboratory Services offer you our Lipoprotein (a) assay as well as our variety of analysers across all RCLS laboratories including our RX Series and Evidence Series as well as third party analysers ensuring the testing abilities are diverse. The Randox Lp(a) assay is one of the only methodologies on the market that detects the non-variable part of the Lp(a) molecule providing accurate and consistent results.

The Different Sample Types Available in Drug & Alcohol Testing Programs

At Randox Testing Services we utilise discreet and non-invasive methods of drug & alcohol testing for comfort and fast sample collection. Offering a choice of a urine test, hair drug test, saliva drug test or a combination of tests, our drug testing methods ensure the possibility for short-term and long-term drug abuse profiling. With different drug testing methods having different windows of detection, we offer advice on which methods to utilise depending upon your company’s drug testing requirements, ensuring the best method or combination of methods is chosen to ensure all your testing needs are fulfilled.

Below we will provide a breakdown of each sample type and accompanying detection windows for the presence of illicit substances.

Urine – Drug & Alcohol Testing

Urine is the most common sample type for drug & alcohol testing. Simple and practical to obtain, it offers short-term drug abuse profiling. It is considered non-intrusive and sample collection is not observed.

Detection window

Drugs: 4 hours – 8 days (30 days for regular cannabis users)

Alcohol: <12 hours

Oral Fluid – Drug Testing

Oral fluid testing analyses a saliva sample for parent drugs and their metabolites. Providing analysis of short-term drug abuse, an oral fluid test is used for with-cause testing and post-incident testing, with results detectable 30-60 minutes after ingestion.

Detection window

Drugs: 24 hours – 48 hours after consumption (drug dependent)

Breath – Alcohol Testing

Breath can be tested for alcohol using handheld devices which provide immediate results. These devices are specific to alcohol and can gauge blood alcohol content (BAC) by measuring deep lung air. This type of testing can accurately determine whether a person has recently consumed alcohol or is currently over the legal or pre-determined limit.

Hair – Drug Testing

A hair drugs test offers a longer window of detection than alternative testing and provides a detailed month-on-month view of overall picture of drug use. This can highlight trends of drug use, suggest abstinence or show evidence of use depending on the length of the hair sample. Our hair testing services are tailored to meet the specific needs of our customers.

Detection window

Typically, up to 90 days using a 3cm sample (1cm of head hair = 1-month detection).

Body hair can be used to provide extended window of up to 1 year

Randox Testing Services

At Randox Testing Services we are committed to improving the safety of workplaces who may be affected by drug & alcohol consumption. We offer a wide range of quality products designed to test for illegal substances quickly and efficiently, ensuring minimal disruption in your workplace.

Why choose hair for drug and alcohol testing?

A hair drugs test offers a longer window of detection than alternative testing and provides a detailed month-on-month view and an overall picture of drug use. This can highlight trends of drug use, suggest abstinence or show evidence of use depending on the length of the hair sample.

When a drug is taken it is absorbed into the blood stream and circulated around the body. As a result, it is incorporated into the hair follicle meaning that as the hair grows, drugs are transferred into the hair strand. It can take up to 2 weeks for drug components to enter the hair and therefore analysis of a 3cm sample is recommended.

Randox Testing Services offer a combined analysis for hair alcohol testing as an aid in the determination of chronic excessive alcohol consumption. A combination test of alcohol markers ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEE) help provide evidence to assess chronic excessive alcohol consumption but cannot be used to demonstrate abstinence of alcohol consumption.

This testing method is commonly used by employers for pre-employment screening which is an increasingly common type of workplace drug and alcohol testing. It forms an essential part of a company’s recruitment process. Hair testing is also heavily used in substance abuse assessment in child protection cases.

Body hair can be used to provide an extended window of up to 1 year of drug use.

Randox Testing Services

At Randox Testing Services we provide drug and alcohol testing to all professional bodies within the medico-legal sector and all workplaces from any industry. Through utilising innovative multiplex drug and alcohol screening methods as well as LC/GC mass spectrometry confirmatory analysis our complete service guarantees reliable and accurate results.

Our hair drug test along with all other testing services are flexible and can be tailored to our customer needs with a choice of testing methods. We offer a comprehensive drugs of abuse test menu and our service also includes expert witness reporting where applicable.

Randox Toxicology: Highest Percentage of Class A Drug Use in over a Decade

Figures released by the Home Office from the Crime Survey of England and Wales for 2017/2018 showed an 8.4 percent rise in 16-24 year olds using Class A drugs in the last year, compared to 7 percent in 2016/2017. As drugs are becoming more readily available due to the Dark Web, mobile phones and drug gangs, a broader network of distribution has been established and the price of cocaine has fallen.

Cocaine is a strong stimulant that comes in a powder (known as coke), freebase or crack form. With short lived effects, cocaine temporarily speeds up the mind and body. Freebase is a powder cocaine that has been prepared for smoking, whilst crack cocaine comes in a rock form. As both forms of cocaine can be smoked, they reach the brain quicker and have a stronger effect than powder cocaine. Injecting any form of the drug has serious risks including, damaged veins and the spread of blood-borne viruses, such as HIV and Hepatitis C. High doses of cocaine can cause the body temperature to rise, resulting in convulsions, a heart attack and heart failure.

The Telegraph recently reported that the fall in cocaine prices has now led to the highest number of young people using Class A drugs in over a decade, a rise from 4.8 percent in 2012/2013. The United Nation’s 2018 World Drug Report states that the street price for a gram of cocaine in the UK in 2016 was £41, the cheapest figure documented at the time since 1990. Compare this to cocaine prices in 2007 when it was £69 per gram.

“Our young people’s services have seen a significant rise in the use of Class A drugs”. Yasmin Batliwala, chair of London based drug and alcohol treatment charity WDP commented on the issue, “The primary drug of choice has always been alcohol, as well as cannabis, but certainly in the last two or more years the use of Class A drugs has increased substantially.” When cocaine and alcohol have been mixed it can cause particularly dangerous side effects and produce a toxic chemical called cocaethylene.

We have the Solution!

Randox Toxicology’s universally available patented Biochip Array Technology boasts cutting-edge multiplex testing capabilities, providing rapid and accurate drug detection from a single sample.

Randox Food Diagnostics: Feed Testing in the Meat Industry – Challenges and Solutions

The global meat industry is a multi-billion-dollar business contributing over $85 billion to the US economy alone annually. Globally it is valued at $800 billion and as such, it is one of the biggest industries in the world.

With its already strong position and an ever growing demand for meat products the market shows no sign of slowing down. There are continued demands set on producers to provide not only more meat, but meat at a higher quality. Public awareness on issues such as drug residues, animal rights, food safety and antibiotic resistance is on the rise and as such producers and processors are more and more required to meet stringent requirements.

With the increasing demand on quantity and quality the industry faces many challenges and one the key areas of interest in this production chain is the monitoring of residues.

Residues in food relates to the residual amount of a particular compound either administered to an animal as a veterinary treatment or a naturally occurring compound present in food for human consumption.

There are a number of potential issues that can arise from contaminated feed and it is important for producers to ensure that animal feed has little or no trace of residues of mycotoxins, growth promoters or veterinary drugs.

Veterinary drugs are often added to feed to be used as a method of treating livestock, producers therefore must be sure of the dosage to ensure that withdrawal periods are correctly adhered to. Mycotoxins may also be present in feed due to a number of environmental factors, this can have a negative impact of the livestock.

The Mycotoxin Threat

Mycotoxins are naturally occurring toxins produced by fungi, commonly known as moulds, which can have a harmful effect on humans and livestock. These moulds are of interest to producers because they have the potential for significant economic losses due to how they impact human health, animal productivity and international trading.

Mycotoxins can be present in a wide variety of foods and feeds and are a particular threat in areas with climates of high temperature and humidity. They can enter the food or feed chain through contaminated crops, in particular cereals, poultry meat and kidneys, pig kidneys and pork sausages. Contamination may also occur post-harvest during storage, transport, and processing stages of the food or feed supply chain.

The establishment of mycotoxin limits and regulations have been set by multiple food agencies worldwide.  For example the EU 2002-32 Directive sets maximum permitted levels (MPLs) for substances that are present in, or on, animal feed that have the potential to pose danger to animal or human health, to the environment, or could have an undesirable affect to livestock production.

One type of livestock that can be significantly impacted by mycotoxins are pigs. Pig feed contaminated with mycotoxins can cause serious risks to pig health.

For example, Aflatoxins consumed by swine can expose non-clinical characteristics with low level exposure (20 to 200 ppb), inducing symptoms displayed such as feed avoidance, gastrointestinal disturbances, paleness and slower growth. It can also suppress the immune system and cause young piglets to become more susceptible to bacterial, viral or parasitic diseases. With prolonged exposure causing a greater risk of cancer, liver damage and jaundice.  High concentrations of aflatoxin (1,000 to 5,000 ppb) result in acute effects, including death. It is a genotoxic carcinogen and suitably its levels have been set as low as realistically possible in complete feeding stuffs for pigs and poultry with a maximum content value of 0.02.

Zearalenone is another mycotoxin that can have a negative impact on livestock. Produced by a strain of Fusarium graminearum it has been listed under the Directive with a guidance value. It has an estrogeneous action and is significantly toxic to the reproductive system of animals with the potential to cause rectal and vaginal prolapses in gilts (young sows). Zearalenone has been allocated a suggested guidance value of 0.1ppm in complementary and complete feeding stuffs for piglets and gilts and 0.25ppm in feedstuffs for sows and fattening pigs.

With the risk from multiple Mycotoxins in animal feed it is important to be able to detect dangerous levels of each listed in the EU Directive in order to reduce instances of damage to animal health.

Growth Promoters

Growth promoters are often used in the meat industry to increase yield of livestock, an important tool considering the increased demand on quantity from the food chain. Some of these growth promoters however are known to have a negative impact on both animal and human health.

The presence of anabolic steroids including beta agonists such as Clenbuterol and Ractopamine, as well as other veterinary drugs is under a strict monitoring program in meat and animal feed to prevent these negative impacts.

Growth promoting drugs are used to induce weight but can have various health concerns such as such as hospitalisation with reversible symptoms of increased heart rate, muscular tremors, headache, nausea, fever, and chills.

The potential human health risks highlight the importance of complete food safety testing before a food product reaches the public.

Veterinary Drugs

Due to the nature of the conditions livestock is generally kept in, there is a high potential for infection and spread of viruses. Producers need to be aware and proactive in treating any veterinary disease that arises.

One such disease that can be an issue is coccidiosis which is a parasitic disease of the intestinal tract. This disease can be spread by contact with infected faeces, or the ingestion of infected tissues by other animals. Coccisiostats are potent drugs which are widely used within veterinary practice to treat coccidiosis, mainly in feed additives. Chickens are susceptible to at least 11 species of coccidia that causes coccidiosis therefore creating an importance to treat for. Coccisiostat residues that occur in high levels within food for human consumption can be unsafe and can have negative effects on pre-existing coronary conditions/diseases. These residues can pass through the meat tissue and eggs.

The Solution

With a variety of potential residues to be detected and a need for accurate results many producers are using Randox Food Diagnostics technology to carry out sample analysis.

With the development of the patented Biochip Array Technology Randox have consolidated the testing of multiple residues down to one sample which means time and cost saving for the meat industry. For example, with one Biochip a meat producer’s laboratory could test for 9 different growth promoter residues.

The technology centres on the Biochip, a 9mm2 ceramic chip which acts as the reaction well where samples are placed, requiring little technical expertise for preparation. Each chip is spotted with the antibodies required to detect the individual analytes being tested for and can accommodate up to 43 analytes. Food laboratories can then detect 43 different residues with one test.

The biochip works on the Evidence Investigator (Semi-Automated) and Evidence MultiSTAT(Automated) analysers. These analysers are used as the imaging stations for the biochips. Each spotted test site sends out a chemiluminescent signal which is detected by the analyser, processed, quantified and validated by the instrument software.

With a simple process, fast method and trusted results many of the world’s top meat producers are investing in Biochip Array Technology to ensure the safety and quality of their products.

RTS: Back-to-Lab Testing

Randox Testing Services offers high quality drug testing with use of our revolutionary Biochip Array Technology specifically optimised for drugs of abuse testing. This technology allows multiplex back-to-lab testing of different drugs from one sample and offers test consolidation for comprehensive testing at an affordable price.

With a comprehensive drugs of abuse test menu we are able to test for a range of different drugs. Drug testing packages can be customised to include multiple different drugs to test per sample.

Our drug testing methods ensure fast and simple sample collection. We have a variety of non-invasive methods for patient comfort including use of a urine sample, hair strand or oral fluid sample to test for specified drugs. Utilisation of different testing methods also ensures flexibility of drug abuse profiling with the ability to offer short-term drug abuse profiling via oral fluid and urine testing, long-term drug abuse profiling via hair testing or a combination of both.

 

Oral Fluid Testing

An oral fluid test can detect drugs for up to 48 hours after consumption. Providing analysis of short-term drug abuse, an oral fluid drug test is used by employers conducting for-cause and post-incident testing, as well as medico-legal solicitors who may require testing for abstinence of drugs.

An oral fluid test consists of obtaining a saliva sample from between the cheek and gums to analyse traces of drugs. This sample method is reliable due to the high concentrations of drug components which remain in the oral cavity for a period of time after drug consumption. Sample collection is taken quickly, easily and is non-invasive. The sample collection is also observed which ensures samples are not tampered with.

 

Urine Testing

A urine test offers short-term detection of substance abuse. Alcohol is detectable in urine for less than 12 hours, and a urine drug test can detect traces of drugs from between 4 hours and up to 8 days (this may be extended for regular cannabis users to around 30 days). It is often used in a combination with hair testing to provide an enhanced time-line for drug and alcohol detection; therefore allowing analysis of chronic substance abuse.

As a simple and practical method it is used as the most common sample type for workplace drug and alcohol testing. It is also utilised when conducting family law testing to ensure no alcohol intake by someone who has been forbidden to consume alcohol by a court of law or someone who is on a drugs or alcohol rehabilitation program.

A urine test consists of gaining a urine sample from the individual securely. Due to the nature of the urine sample being deposited privately by the sample donor, measures need to be taken to ensure the sample is not tampered with. At Randox Testing Services samples are collected under strict chain of custody protocols to guarantee sample integrity for legally defensible testing. We also increase accuracy of results by testing for creatinine which is a simple method of testing the authenticity of the sample given and reduces false-negative results giving you confidence in these testing methods.

Hair Testing

Hair testing is a long-term substance abuse profiling with a detection window of 90+ days. It is commonly used by recruiters and employers conducting pre-employment screening and is the most common sample type used for substance abuse assessment in child protection and medico-legal cases.

Hair testing involves taking a hair stand sample from an individual to detect if and approximately when someone has consumed drugs or alcohol. A 3cm sample is generally used to obtain a longer analysis of substance abuse.

When a drug is taken it is absorbed into the blood stream and circulated around the body. As a result it is incorporated into the hair follicle meaning that as the hair grows, drugs are transferred into the hair strand. It can take up to 2 weeks for drug components to enter the hair and therefore analysis of a 3cm sample is recommended.

Analysis of the hair strand allows traces of drugs to be detected to provide an overall picture of drug abuse or a month by month analysis. Segmentation of the hair sample to provide a detailed month-on-month view is advantageous as it can highlight trends of drug use and identify periods of abstinence or high level use. Body hair can be used in special circumstances however segmentation into a month by month analysis is not possible.

RTS: The Dangers of Psychoactive Substances

Psychoactive substances, formerly known as legal highs, are substances which produce the same or similar effects as many illegal drugs such as cannabis, ecstasy and cocaine. With many psychoactive substances it is extremely difficult to know their potency and therefore how they will affect the user.

They are divided into four main groups:

Sedatives – Cause reduced concentration and slowing of reactions, leading user to feel physically unsteady and lethargic.

Hallucinogenic – These substances cause psychedelic reactions which can lead the user to act erratically, putting their own safety at risk.

Stimulants – Substance temporarily causes increase in alertness and energy, while also putting a strain on the nervous system.

Synthetic Cannabinoids – Large doses can lead to life-threatening intoxication. Also effects the central nervous system causing seizures, high blood pressure, rapid heart rate and increased body temperature.

Incidents

Last month two men were arrested and jailed for four and a half years for selling psychoactive substances. The offences were committed in Scotland and eight of the men’s customers needed hospital treatment after taking the substances.

Free samples and loyalty cards were used by the men selling the psychoactive substances and two users were left in comas after taking a substance known as Psyclone. Court was told that the shops took in as much as £2,500 in sales every day.

The sister of a man who died from taking psychoactive substances said it changed her brother “mentally and physically.” BBC Scotland was told that he started dabbling with psychoactive substances because he believed they were legal. “Some of them were a substitute of heroin, others to mimic the effects of cannabis. He became very withdrawn with the family and just wanted to stay away.”

 

Randox Testing Services

At Randox Testing Services we reacted to the issues caused by psychoactive substances by releasing the world’s first Synthetic Cannabinoids (JWH/AM) and ‘Bath Salt’s’ (MPDV) tests in 2012. This enables companies to test for popular types of psychoactive substances and showed that it was possible to detect these substances.
