Nearly 1 in every 3 people with coronavirus do not have any symptoms. These people won’t know they have the virus but can still pass it onto others. This means that a quick and easy test to tell if people who don’t have symptoms carry the virus is very useful to control the spread of the virus and protect those around us. The tests are being used to “screen” people for the virus.

How to take your rapid antigen test
Product Info
Helagen's COVID-19 Ag Rapid Test Cassette (swab) is a rapid antigen test to detect the SARS-CoV-2 virus from a simple nose swab. The test uses "lateral flow" technology similar to a home pregnancy test.
This test is one of three to pass assessment by Public Health England and is approved by the EU.
It has been shown to detect both the Kent and South African variants of SARS-CoV-2 coronavirus.
Useful Documents
Important considerations for use:
- If you have typical symptoms of coronavirus, you should take a PCR test.
- Positive results hould be confirmed by molecular test such as PCR.
- A negative test result does not guarantee that an individual doesn't have coronavirus.
- These tests are sold for use by appropriately trained indivduals and is not intended for home use.
We've gathered together a list of the most common questions people have. If you can't find the answer you're looking for please do get in touch.
Lateral flow antigen tests are best used to detect coronavirus in people who don’t have symptoms.
You can use these tests even if you have been vaccinated. We know that vaccines are not perfect at stopping people from getting the virus and people who have been vaccinated can potentially still carry the virus and infect others.
If you have symptoms of coronavirus (e.g. persistent cough, fever, change in sense of taste/smell), you should take a PCR test instead of, or in addition to, a lateral flow antigen test.
If you have had coronavirus confirmed by a PCR test, the NHS recommends that you can avoid regular testing with rapid antigen tests for 90 days.
When using these tests to screen for coronavirus, it is best to take a test regularly. This should be at least once per week and studies suggest best results when testing twice per week.
However, there may also be times when you need to take a test as a “one-off”. For example, when you are coming into contact with a group of people for an event or when travelling.
Clinical evaluation of lateral flow tests shows that they work best at picking up the virus when a person has high levels of the virus. In most people, high levels of the virus last for 4-8 days and corresponds to when they are most likely to transmit the virus to others.
This test correctly identified people with high levels of the virus in 99% of cases. This means that if 100 people with the virus took the test, we would expect a positive result in 99 of them. Furthermore, almost everyone with a positive test result did actually have the virus – there were virtually no “false positive” results.
However, we do know that lateral flow tests are not as good at picking up low levels of the virus as a PCR test. However, PCR tests have to be done in a lab, take a lot longer to produce a result and are so sensitive that they can be positive weeks to months after people have stopped being infectious.
If you test positive then it’s highly likely that you’re infected with coronavirus, even if you have no symptoms. You should isolate immediately and arrange to take a PCR test (e.g. with NHS Test and Trace) as soon as possible. You’ll need to isolate until your PCR test result is back. If the PCR test confirms that you have the virus, you’ll need to stay in isolation for a total of 10 days from when you took your antigen test.
