To check if you are carrying the virus and are infectious to others.

To quickly check if you are infectious to others, to prevent risks to the health of others. With results in 15 minutes this test will confirm if you are a risk to others and let you know if you are infected with SARS-CoV-2.

Workplaces and other organisations will benefit from regular testing to ensure they are not at risk of infecting each other.

The test is a lateral flow immunoassay test and operates in a similar way to a pregnancy test. Embedded into the test strip are antibodies that bind to a SARS-CoV-2 specific biomarker, Immunoglobulin G (IgG), and another infection biomarker, Immunoglobulin M (IgM).

When a sample is added to one end of the test, it flows along the test strip and interacts with these antibodies. If the patient has contracted SARS-CoV-2, the biomarkers in their blood will bind to the antibodies on the test strip, leaving a visible test line. If the patient doesn’t have SARS-CoV-2, no biomarkers should be present in their blood and no test line will be visible. There are separate test lines for IgG and IgM and only one needs to be visible for
a positive result.

It is a swab test which detects the presence of protein particles from the virus that causes the SARS-CoV-2 virus.

The test must be administered by a trained healthcare professional. A swab is taken from the nose, a fluid is added and this fluid is then tested for the presence of viral protein using a lateral flow device.

Results are observed within 15 minutes. Positive results might be observed much sooner and will be valid

The Flowflex test is UK Government Validated, MHRA Registered, CE Approved and ISO Certified.

The buffer solution has two functions. It acts as the carrier for the sample, allowing it to laterally flow along the test strip, and it maintains a constant sample pH as it flows, preventing degradation of the biomarkers and the antibodies. You should only use the buffer solution provided with the test kits.

Yes, the test will be able to detect asymptomatic people, as they will have an immune response even though they don’t display symptoms.

For the result, the window of accuracy is 15-20 minutes after you add the sample and buffer solution. If you forget to read the results after this time you should consider the test to be invalid.

The shelf-life is 18 months from the date of manufacture. The product expiry is printed onto the packaging for reference. Do not use after the expiry date.

The recommended storage temperature is 4 – 30°C, however, we do not recommend you store them in the fridge, unless there is a risk of them overheating. Do not freeze the test cassettes or buffer solution. Tests should be performed at room temperature (15 – 30°C), so if you have stored tests in the fridge, you should allow them to reach room temperature before performing a test.

To date we have tested numerous common pharmaceuticals, none of which have interfered with the test, hence we currently see no cross-reactivity issues. We are looking at more drugs and will update customers accordingly.

Yes, there are no issues with testing babies and young children provided the instructions are followed correctly.

Yes, there is no harm to the mother or baby when performing a test.
