This antigen test can be performed at home by the client. Antigen tests detect viral RNA. This requires taking a swab from the nose and throat and then analysing the specimen in the lab using the polymerase chain reaction (PCR). You may see these tests referred to as PCR tests. They aim to answer: do I carry coronavirus now? If you want to see if you have had covid-19 and developed antibodies, you should take an antibody test.

The chances of detecting virus are highest in the days surrounding the start of symptoms. Ideally samples should be taken from symptomatic individuals between days 1-5 from symptom onset. However, there are many cases when virus can be detected later into the illness. A negative test result is also useful, to tell you that there is no presence of virus on that swab. But please bear in mind that this may be a false negative and isolation guidelines should still be followed. Many institutions use two swabs, 24 hrs apart to confirm a negative case alongside other clinical information.

You can take an antibody test from 14 days after the onset of your symptoms. The test is used to detect antibodies made in response to infection and therefore possible immunity. You can read more about the different types of tests here

Send the test back by Royal Mail Special Delivery directly to us. We will deliver the samples to our laboratory before 4PM that day, meaning results the following day.

We only use laboratories with the highest accreditation standards. The organisation that supplies us with the test is on the approved list on the NHS and PHE. This is the same laboratory that supplies us our Abbot antibody test test.

Note that results must be evaluated within the clinical context, which is why this is a clinical service which includes the test, advice on test results and further clinical management.

The used at our laboratory show a minimum sensitivity of 98% and a specificity of 100% when the virus is on the swab with no cross-reactivity with other viruses. This is when the test is performed correctly. The sensitivity can fall for a number of reasons and it is important for the results to be reviewed within their clinical context.

Please note, the demand for this home testing kit clinical service is high. Your testing kit will generally arrive inside 3 working days from the date of your order.

 

Our recommendation is to use both the COVID-19 Antibody and PCR COVID-19 clinical testing service. This is the only way to be certain that you have developed an immune response and that the Covid-19 virus has left your body. We also offer both the Abbott Antibody and PCR COVID-19 as home testing services.
