World Antibiotic Awareness Week at Randox

The global crisis of antimicrobial resistance is never far from the headlines. As part of World Amicrobial Awareness Week, we’ve been discussing the dangers and importantly the work being done to combat this growing threat.

There’s a very simple reason why we must all do what we can to tackle AMR. This year it’s thought 700,000 people died from drug resistant illnesses such as bacterial infections, malaria, HIV/Aids or tuberculosis. Experts warn that by 2050, this figure will rise to 10million.

Randox’s aim is to revolutionise global healthcare and we are committed to combating the threat of antibiotic resistance. We have a number of tests on the market that can help the fight against AMR, strengthen consumer confidence and ensure quality and safety for a number of different industries. So to round off this week, we spoke to two of our experts at Randox: Business Development Manager, Dr Mary Jo Kurth, and Molecular Diagnostics Manager, Dr Martin Crockard.

70% GP’s have been reported to prescribe antibiotics when they don’t know whether the infection is caused by the virus or bacteria.

At the frontline of the battle to curb AMR are the GPs but they’re not able to access the latest technology which can help them. Dr Mary Jo Kurth said, “In the current GP setting, diagnostic testing to determine whether a respiratory infection is bacterial or viral is unavailable, and therefore doctors often have to guess – or feel pressurised into prescribing antibiotics because patients demand it. However antibiotics only work to treat bacterial infections and are useless in treating infections that are caused by viruses.

 “The consequences are severe. Medical procedures like organ transplantation and cancer chemotherapy need antibiotics to prevent and treat the bacterial infections that can be caused by the treatment. Without effective antibiotics, even routine operations could become high risk procedures if serious infections can’t be treated. The hard won victories against infectious diseases of the last fifty years will be jeopardized.”

Our Biosciences division have developed a test that can rapidly detect and identify the cause of 22 respiratory infections, in both the upper and lower respiratory tract, and therefore subsequently determine if an antibiotic is required as well as then identify the most effective antibiotic to take. Additionally our Confidante kit – the world’s first over-the-counter home sexual health test – can detect ten of the most common STIs with one patient sample and deliver accurate and reliable results securely and discreetly within one week. This takes the guesswork out of antibiotic prescription and could go a long way in fighting the antibiotic resistance crisis.

Dr Martin Crockard said, “Identifying the specific cause of illnesses provides opportunities to tailor treatment, reducing antibiotic misuse. Not all infections respond to antibiotics, however a multiplex approach which identifies bacterial, viral or fungal pathogens encourages improved clinical decision-making, refining treatment, leading to enhanced patient care.

The molecular group here at Randox are developing a range of multiplex infection detection arrays to identify specific infection agents, allowing more appropriate use of antibiotics to improve patient care and reduce the onset of antibiotic resistance.”

In addition to tackling AMR via medical settings, there is work that can be done to deal with it in our food. Randox Food Diagnostics offer a comprehensive range of diagnostic solutions to allow for the detection and quantification of antibiotic residues within animal and food products. With validation across a range of matrices Randox Food allows producers to ensure their products are free from antibiotic residues.

As consumer awareness develops so does the need for antibiotic screening within agriculture and food production. Guaranteeing an antibiotic-free product strengthens consumer confidence and ensures food integrity on a global scale. Randox Food offers the Evidence Investigator matched with biochip array technology to provide the end user with fast, reliable results to ensure antibiotic free produce.

The UK Government recently commissioned a two year review into the crisis. Led by Lord Jim O’Neill, the final report outlined a new system of ‘market entry rewards’ worth $1.6 billion to the successful developer of a new antibiotic, which meets a prospectively-defined criteria of ‘unmet need’. Developers of alternative therapies aimed at tackling areas where there is unmet need due to rising AMR would also be eligible for these rewards. Such rewards would be paid after a successful product comes to market.

Chief Medical Officer, Dame Sally Davies said, “Antimicrobial resistance poses a catastrophic threat. If we don’t act now, any one of us could go into hospital in 20 years for minor surgery and die because of an ordinary infection that can’t be treated by antibiotics. That’s why governments and organisations across the world, including the World Health Organization and G8, need to take this seriously.

“This is not just about government action. We need to encourage more innovation in the development of antibiotics – over the past two decades there has been a discovery void around antibiotics, meaning diseases have evolved faster than the drugs to treat them.”

AMR will not go away on its own. It requires complex and comprehensive action across many sectors.

The UK Government is being urged to ban excessive use of antibiotics in farming

To coincide with the start of World Antibiotic Awareness Week the UK Government is being urged to ban excessive use of antibiotics in farming by a group of leading doctors, according to The Daily Telegraph.

Made up of 12 royal medical colleges, the British Medical Association and the Faculty of Public Health, the group say that the UK should “use the opportunity afforded by Brexit to lead the world in banning” preventative prescription of medicines on animals.

A decision made by the European Parliament earlier this year to ban mass agricultural medication has not yet been ratified by member states or the European Commission.

A Department of Environment, Food and Rural Affairs’ spokesman told the newspaper that dealing with AMR is a “top priority” though the paper notes it ‘stopped short of promising a ban.’

In 2015 McDonalds set itself a two year deadline to stop its US restaurants buying chicken raised with human antibiotics. It led to one of the US’s leading meat producers – Tyson Foods – promising to end the practice by September 2017 – which is, as The Guardian stated, “one of the most aggressive timelines yet set by an American poultry company.” The company’s CEO Donnie Smith told the newspaper: “We have found as we have reduced the level of antibiotics we use, whether it’s human use or vet-only, our cost has actually gone down. A lot of the ways we’ve been able to accomplish this is by working with our farmers on better husbandry practices. If this millennial mum wants a no-antibiotic ever..nugget we better supply that.”

Farmers Weekly reported this month on a Danish Crown initiative launched in 2015 whereby pig farmers attach an antibiotics-free tag to piglets at the neonatal stage. It’s removed at any point if antibiotic treatment is deemed necessary. It claims that although early farm trials suggest a production fall of up to 2.5 piglet per sow per year, the “premium covers additional costs if 35% or more piglets carry the tag to the slaughterhouse.”

Pig farmer Stine Mikkelsen carried out a major review of hygiene and health on her farm to reduce antimicrobial use to boost revenue by £11.25 per pig. She says that although production is down and labour costs did increase, it “feels good” to farm in this way. She told the newspaper, “I am very motivated to do something about it – it’s a hard route to take but I have a good feeling about this system.”

Randox Food Diagnostics is working with global leaders in the food industry to tackle antibiotic resistance and safeguard their use for both human and veterinary treatment.

Using a dedicated research and development team, Randox have the ability to respond rapidly to emerging new drugs of abuse and regulations in relation to food and animal safety, with sixty-five new residue drug targets are currently in development to keep up with the ever changing market of food safety. Randox Food Diagnostics are ensuring that all residue screening laboratories requirements are met by providing reliable food safety screening on a global scale.

On top of the food safety product range Randox Food also offer a range of analysers, reagents and test kits for use throughout the winemaking process to ensure quality is maintained in every bottle.

This product range includes the RX misano semi-automated wine analyser and the RX Monaco fully automated wine analyser.

The RX misano is currently unavailable to purchase in Germany


What is Calibration Verification & why is it so important?

What is Calibration Verification or Linearity?

Calibration Verification, or Linearity assessment, is becoming a fundamental element for laboratories in the USA who have access to instrumentation used in the running of patient samples.

Linearity is the ability to provide results that are directly proportional to the concentration of the analyte in the test sample. CLIA defines this as the assaying of materials of known concentrations in the same manner as a patient sample to verify the instruments linearity throughout the reportable range. By performing calibration verification a lab is assessing if their test system’s calibration is still valid and if their chosen method is linear across the full reportable range, it will also supplement their existing QC and EQA/PT by challenging a larger segment of the AMR (Analytical Measuring Range). According to CLIA, a laboratory should perform, and document, calibration verification procedures at least once every 6 months or whenever one of a number of other factors occur, for example, a complete change of reagents, major preventative maintenance or replacement of parts, new instrument validation or when their control material is highlighting unusual shifts or trends in performance.

It is commonplace for laboratories to confuse calibration verification and reportable range, so much so, that advice and guidance is continually being asked for by laboratories. In short, reportable range is one of the first characteristics that should be used as an evaluation tool whereas calibration verification should be viewed as a continual performance check.

How it works

Aside from carrying out testing twice per year, CLIA also recommend that a minimum of 3 levels are tested (although most laboratories prefer to test 5) covering the low end, mid-point and high end of the instruments reportable range. Labs should run at least 2 replicates of each level in the same way they would a patient or control sample. The results are then plotted against the target values provided, if the results obtained are within the pre-established limits then the performance is considered acceptable. The degree to which the plotted curve conforms to a straight line is a measure of system linearity.

In many cases, data reduction software is provided with the product and this can be used to automatically plot results. This software is also capable of comparing results to peer group data for troubleshooting purposes.

Randox Linearity Sets

Our Acusera Linearity Sets and Verify data reduction software will provide laboratories the chance to test low, medium and high ranges on their instrumentation – in doing so, labs will keep in line with CLIA recommended bi-annual testing as well as ensuring their instrumentation is performing well across the full reportable range.

Designed with convenience in mind, our sets cover a wide range of clinical testing including; Cardiac Markers, Therapeutic Drugs and Specific Proteins in a liquid ready-to-use format. The varying levels and combination of unique analytes enables laboratories to consolidate testing and reduce the number of individual products required.

Complementing our Linearity sets is our data reduction software, Acusera Verify. When used in conjunction with our sets you can effectively challenge your instrument across the full reportable range while ensuring accurate and reliable patient testing. Some features of our software include easy to interpret charts for at-a-glance performance, access to real-time peer group data to enhance troubleshooting and an intuitive user interface for simple data entry.
