We believe that frequent testing is the key to keeping COVID-19 in check.
There are two kinds of tests available for the COVID-19 virus and related infection: antigen tests and antibody tests.
An antigen is a structure recognised as foreign by the human body. An antigen test tells you if you have a current virus infection.
Antibodies are proteins produced naturally in response to seeing foreign structures (e.g. virus antigens). An antibody test will confirm if you have developed antibodies to the virus infection.
There are three different tests. PCR (polymerase chain reaction), LAMP (Loop-Mediated Isothermal Amplification) and Lateral Flow tests. PCR and LAMP tests require laboratory equipment to analyse the samples and can take some time to provide a result. Lateral Flow tests do not require additional equipment and can provide a result within a very short period of time.
The DNA Diagnostic Rapid Covid-19 test is a Lateral Flow Test to detect antigens.
Lateral flow tests, also known as lateral flow immunochromatographic assays, are simple devices intended to detect the presence of a target substance in a liquid sample without the need for specialised and costly equipment. The most common use of lateral flow testing is in diagnostics for pregnancy, which tend to test for the human chorionic gonadotropin (hCG) hormone present in urine if a woman is pregnant. A variety of biological samples can be tested using a lateral flow test, including urine, saliva, sweat, serum, plasma, whole blood and other fluids.
The DNA Diagnostic Rapid test detects the presence of viral proteins (antigens) expressed by the COVID-19 virus in a sample taken from the respiratory tract of a person. If the target antigen is present in sufficient concentrations in the sample, it will bind to specific antibodies fixed to a paper strip enclosed in a plastic casing and generate a visually detectable signal, typically within 15-30 minutes. The antigens) detected are expressed only when the virus is actively replicating; therefore, such tests are best used to identify acute or early infection.
See table below.
The PCR test is the gold standard for Covid-19 testing. Clinical trials show the DNA Diagnostic test matches these tests 96% of the time.
Regular frequency of testing will give a faster and more reassuring measure of protection than a highly accurate test that is performed sporadically. This outlined by the UK government in their plans to roll out mass testing (Operation Moonshot).
Our kit is to be used as a supplementary detection indicator and cannot be used as a sole basis for the diagnosis of Covid-19. In the event of a positive test, you should arrange to have a PCR test asap.
The cost is higher but more importantly the time to get results is much longer. This means even if there is availability it can be difficult to get a test because of backlog in labs. To test often with 96% accuracy is better than to test less frequently or not at all.
Any company or organisation that wants to check their staff, visitors or customers.
Healthcare professionals and/or a person who has received adequate training.
No, as it requires trained staff to carry out, we cannot sell to private households.
We can recommend professionals that can train your staff to use the tests or alternatively we work with organisations that can come to your workplace and administer them. Prices of these services vary depending on what and when you need them.
It is taken using a nasal swab which is more user friendly and has a higher level of compliance than a nose and throat swab.
Test results are available in 15 minutes.
Yes, absolutely. Like all tests this is simply one of many complementary measures to improve safety that must be followed until the pandemic ends.
As often as you think is necessary to provide a safe environment. Each company should be carrying out their own risk assessment, looking at their individual circumstances and decide what suits their safety protocols.
50 units is the minimum order
The kits come with all the components however the person administering them must take appropriate precautions and be wearing recommended PPE.
We do have some stock for smaller orders but as a rule lead times are currently 21 days. Orders should be placed as far in advance as possible to ensure your tests can be delivered in time to meet your organisations’ requirements.
Tests do not need any special storage conditions. They should be kept between 2°C and 30°C.
Covid-19 infection is often asymptomatic. Therefore, the idea of testing is to be proactive and frequently test your staff and ensure those that test positive (even without showing symptoms) can self-isolate. The sooner you catch an outbreak the sooner you can stop the spread. However, it all depends on your business and your risk assessment.
The cost of testing and the frequency is relative to your organisations needs and risk assessment. In some cases, an outbreak can lead to a business having to shut down and this can lead to a large loss in revenue which could be higher than the cost of regular testing.
At the moment the government will not accept the result of an antigen test as a reason to stop following its guidelines. This is another reason for testing regularly before an outbreak to reduce the chances of the virus spreading amongst your workforce and causing disruption.
