Flu is a contagious respiratory illness cause by influenza viruses that infect the throat, nose, and sometimes lungs. It can cause illness and sometimes death. Getting vaccinated is the best way to prevent catching flu .
There are four types of seasonal flu, A, B, C, and D. Types A and B cause seasonal epidemics of disease. Illnesses range from severe to mild and can even result in death in high risk groups. High risk groups include, pregnant women, children under 5 years of age, the elderly, and people with chronic or immunosuppressive medical conditions .
Symptoms of Flu 
• Sudden fever (temperature above 38C)
• Feeling tired
• Sore throat
• Loss of appetite
• Chesty cough
A test to detect Influenza viruses can be used to determine whether a patient has the flu. A swab is taken from either the nose or back of the throat and sent for testing. Molecular assays can be used to detect genetic material of the virus . Molecular methods play an important role in the diagnosis and surveillance of influenza viruses. Molecular diagnostics allow timely and accurate detection of influenza and are already implemented in many laboratories. The combination of automated purification of nucleic acids with real-time PCR should enable even more rapid identification of viral pathogens such as influenza viruses in clinical material .
The spread of Flu
Flu season begins as early as October, reaches its peak in February, and ends in March. In the southern hemisphere, flu season falls between June and September. Wherever it’s cold, it’s flu season. This can be seen in Figure A below, which shows google searches for the term ‘flu’ for the last five years for USA (northern hemisphere) and Australia (southern hemisphere). It is obvious that flu is prevalent at different times in the northern and southern hemisphere.
However, it’s a common misconception that flu is caused by the cold. There are many theories as to why the flu season comes in winter :
1. People spend more time indoors, with windows closed, not getting fresh air.
2. A lack of Vitamin D and melatonin from reduced sunlight, weakening the immune system.
3. Influenza virus thrives in the cold, dry air of winter
Of course, there have been attempts to test these theories, but animals do not contract the virus like humans, so testing is difficult. A researcher named Peter Palese decided to test theory 3 after finding an old medical journal article that reported guinea pigs are infected and spread the flu like humans.
Figure A. Google Searches for ‘Flu’ in USA and Australia for the last 5 years 
Having set up cages with varying temperatures and relative humidity, he observed how they affected the spread of the flu virus. He found Influenza spread more effectively in cold, dry air .
A theory about why this is the case is associated with how the virus moves through the air. When someone breaths out, they release little virus-containing droplets in to the air. The droplet then begins to evaporate. A lower relative humidity means there is less water in the air, meaning there is more room in the air for additional moisture, allowing the droplets to evaporate. A higher humidity means the droplet can’t evaporate because there isn’t as much room for more moisture, and the virus is not suspended into the air .
Whatever the case, the fact remains: when winter comes around, the flu will follow.
You can avoid catching the flu by getting the flu shot, investing in a humidifier, keeping your hands clean, and limiting contact with those who are already ill. Immunity gained from vaccination decreases over time, so annual vaccination is recommended. Vaccines are most effective when they closely match viruses in circulation. The constantly evolving nature of Influenza viruses requires the WHO Global Surveillance and Response System to monitor influenza viruses around the world and update vaccinations accordingly.
Personal protective measures can be taken in addition to vaccination :
• Properly washing and drying the hands
• Covering the mouth and nose when coughing and sneezing
• Self-isolation when showing symptoms of influenza
• Avoiding contact with sick people
• Avoiding touching the eyes, nose, and mouth

What is Lyophilisation?
Lyophilisation or ‘freeze drying’ is the process by which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase. The process consists of three separate processes:
- Primary Drying (Sublimation)
- Secondary Drying (Desorption)
There are many benefits to using a lyophilised control including; improved product shelf-life and enhanced stability of volatile analytes. For example, many lyophilised controls have a shelf life of up to four years from the date of manufacture resulting in a reduction of costly new lot validation studies. Furthermore, lyophilised controls can be aliquoted and refrozen to extend the working stability of the product.
Reconstituting Lyophilised QC Material
The process of reconstitution involves adding a specified volume of distilled water to lyophilised QC material. The water should completely dissolve the lyophilised contents, giving a liquid solution, which is ready for analysis.
Reconstitution is a straightforward process, but requires a high level of precision. Small errors can have serious implications to the reconstituted material:
- If too much water is pipetted during reconstitution, the material will be heavily diluted and results will be lower than expected
- If too little water is pipetted during reconstitution, the material will not be sufficiently diluted, and results will be higher than expected
- If the correct volume of water is pipetted, but a small amount of water gets stuck in the pipette tip due to poor pipetting technique, results will be higher than expected
If a lyophilised control has been reconstituted incorrectly the contents of the vial will be wasted. It is therefore vitally important that controls are reconstituted with care.
Materials and Methods Required
The list of requirements for an accurate and consistent reconstitution technique is not extensive, but each requirement is vital. Labs should have:
- Calibrated volumetric pipettes
- Sterile, appropriately sized pipette tips
- Distilled water, or other reconstitution fluid as specified
- Technician with good pipetting technique
- Lyophilised QC stored according to manufacturer’s specifications
How to Reconstitute Lyophilised QC Material
Each different lyophilised control may require slightly different preparation, always refer to the instructions for use before reconstituting control material. The below guide provides a general overview of the reconstitution process, using the Randox Human Assayed Chemistry Premium Plus control (HN1530) as an example
- Place the vial of lyophilised QC on a flat surface, carefully remove the lid and the rubber stopper making sure not to spill any material
- Using a calibrated pipette and sterilised pipette tip, add exactly 5ml of distilled water directly into the QC vial, ensuring no water is left in the pipette tip, or on the rim/side of the vial
- Place the rubber stopper and lid firmly back onto the QC vial, and leave to stand for 30 minutes
- After 30 minutes, gently invert the QC vial 10-15 times to ensure the contents is completely dissolved, making sure to avoid the formation of foam. It is important that you DO NOT SHAKE the vial. Alternatively place the vial on a roller for 30 minutes to ensure the contents is thoroughly mixed
- Once satisfied all material has been completely dissolved, proceed to use the QC product in accordance with the ‘Control’ section of the individual analyser application
- Once finished, refrigerate any unused material. It is good practice to label the vial with the date of reconstitution to prevent the use of material outside of the recommended stability period
- Prior to reusing lyophilised material, mix the contents thoroughly by gentle inversion, as highlighted in Step 4
It is important to remember that there may be slightly different reconstitution requirements for different QC material. For this reason, it is vital that the instructions provided on the QC Kit Inserts are closely followed.
Reconstituting lyophilised QC can be time-consuming. Therefore, Randox Acusera offer convenient 5ml distilled water serum diluent to assist laboratories with reconstitution of lyophilised controls. These user-friendly pour over vials streamline the reconstitution process and eliminate the risk of pipetting errors.

External Quality Assessment (EQA) is a vital aspect of laboratory testing and is often a regulatory requirement. The primary function of EQA is to provide the laboratory with an indication of test system accuracy through interlaboratory comparison. Ultimately participation in an EQA programme will give the laboratory greater confidence in the accuracy and reliability of the results they release.
When choosing an EQA scheme there are a variety of different options. It is important that laboratories weigh up the pros and cons of each option in order to choose the scheme that best suits their needs.
Many EQA schemes promote the distribution of multiple EQA samples per challenge or testing event as a benefit to the laboratory. By analysing multiple samples at each testing event, laboratories believe they are challenging their test system across a wider range of concentrations than would be possible if they were to analyse just one sample. However, this is not always the case as in many instances the levels can be very similar. Another consideration is the EQA report received by the laboratory. EQA reports are used to assess analytical performance and identify any test system failures, such reports can take more than one month to receive. In such instances it would be more beneficial if the laboratory tested just one sample at each bi-weekly/monthly challenge and received their report faster.
Report frequency should be priority for any laboratory when choosing an EQA scheme. A fast turnaround time will allow any test system errors to be identified sooner and necessary corrective actions to be taken immediately with minimum disruption to the lab. Perhaps the most important benefits of a rapid report turnaround is cost and time savings as it will significantly reduce the time and money spent re-running patient samples.
If the time between sending EQA results back to the organizer and receiving an EQA report is too long, it becomes more difficult to pin-point exactly when an error was encountered thus increasing the possibility of incorrect test results and possible misdiagnosis. While this would be considered the worst-case scenario, it is still a possibility.
Choosing an EQA provider that delivers both frequent analysis and a quick report turnaround will give the laboratories the confidence they need to report patient test results.
With the Randox International Quality Assessment Scheme (RIQAS), comprehensive reports are available within 72-hours of the submission deadline. Furthermore both bi-weekly and monthly analysis options are available.

Get your teeth into a Randox commutable control this Halloween
It is that time of year again – when people dress up, children trick-or-treat and many a scary story is told in households around the world. An age-old tradition celebrated globally by millions of people – it can only be Halloween.
Last year Randox QC brought you the truly scary story about a laboratory who chose not to use a third party control, but eventually “treated their laboratory to a true third party control”. This year, we have another scary story for you about a lab manager in Transylvania, Dr. Acula.
It was a normal, busy day in the lab for Dr. Acula. That was until it was time to change reagent batch, after changing batch of reagent Dr. Acula was shocked to find his QC results had shifted by over 20%. This left Dr. Acula very frustrated, having to spend precious time troubleshooting and reassigning QC targets. After troubleshooting showed no apparent root cause, Dr. Acula searched the internet for an answer finally stumbling upon an educational guide from Randox Quality Control on commutability and its many benefits to the lab.
Grinning from ear-to-ear with excitement, Dr. Acula began to read the guide in the hope of finding a solution to his problem – and solutions he found. While reading the guide, Dr. Acula came across a quote from ISO 15189:2012. It read that laboratories “must use quality control materials that react to the examining system in a manner as close as possible to the patient sample”.
Dr. Acula made a decision to look for a commutable control material that met all of his requirements and he didn’t have to search very far. Randox Quality Control were able to supply Dr. Acula and his laboratory with a QC material to meet all his needs – true third party, excellent stability, consistency and consolidation but most importantly of all commutable controls. The fact all Randox immunoassay and immunology controls are manufactured from 100% human material appealed to Dr. Acula a lot. After trialing the Randox control material alongside patient samples and comparing results between reagent batches, Dr. Acula was thrilled with the results.
Labs rely heavily on quality control to detect errors in their test system and to ultimately make critical decisions regarding the accuracy and reliability of patient test results, the use of a control that reacts to the test system in the same manner as a patient sample is therefore essential.
At Randox Quality Control we take quality seriously. All our QC products are manufactured to the highest possible standard ensuring controls of unrivalled quality time and time again. Designed to be commutable, the Acusera range will ensure accurate and reliable instrument performance while simultaneously helping laboratories meet ISO 15189:2012 requirements.
Just ask Dr. Acula, who likes our 100% human controls so much he has started to drink them himself!
World Heart Day – 29th September – Introduction
This year (29th September 2017) join us as we help to raise awareness for World Heart Day! The theme for this year’s World Heart Day is to share the power – and you know what they say… “Knowledge is Power” so throughout this blog we will be providing vital knowledge as well as tips to having a healthy heart!
The heart is a muscular organ that pumps blood around the body and is indeed central to your circulatory system. The system consists of a network of blood vessels, including, veins, arteries and capillaries. These vessels transport blood – as well as carrying oxygen and other important nutrients – to every part of the body. Ensuring a healthy heart is therefore vital.
What is CVD?
When too much pressure is put on our hearts we start to run into some issues – the general term for conditions affecting the heart is Cardiovascular Disease – better known as CVD. The exact cause of CVD is far from clear, with many factors increasing your chances of developing CVD. These risk factors can include, but are not limited to, high blood pressure, smoking, high cholesterol, being overweight or in many cases, can be hereditary.
It is important to note that Cardiovascular Disease is accountable for nearly half of all non-communicable disease (NCD) deaths, therefore making it the number one killer across the globe! Scary thought considering there are a whopping 17.3 million CVD related deaths per year – including stroke and heart disease. Understanding CVD in today’s society is more important than ever before, we need to know the truth about CVD and be able to decipher the facts from the fiction. Below you can see a few examples of common misconceptions regarding CVD and also some that are indeed true.
Only older men can get heart disease/CVD
Cardiovascular Disease can develop before birth
Exercising won’t help if you’re genetically predisposed to CVD
Low and middle-income countries are the most susceptible to CVD
It is estimated that by 2030 the number of deaths, due to CVD, will rise to an enormous 23 million globally! However, by raising awareness of the critical numbers and facts we can all help prevent CVD by making small, simple lifestyle changes.
Tips for a Healthy Heart
Using our “art into heart” graphic below, we decided to outline some of our Randox QC top tips for staying healthy! Why not try some of them and feel the effects of having a happy, healthy heart!
