See a list of the current requirements for certain countries here

Or maybe you need a test to return to work, your child might require one to go back to school or Doctor has requested you have one before you attend a private hospital for a scheduled procedure?

Here at the Private Harley Street Clinic, we offer a fast, dedicated, turnaround service to facilitate all of these requirements and more.

How quickly will I get the results?

Please read carefully..

For clarification, the timing of receiving your results can be anywhere between 24-48 hours after your test. Generally we get 90% of results back to people in 24 hours however things such as capacity at the laboratory and test re-runs can mean results take slightly longer. We are not liable for any other associated costs should your results be delayed.

If you prefer to self administer the test, there is a Tracked24 prepaid label included with your test. Drop this to any of the Royal Mail Priority boxes and the laboratory will receive it the next working day. Results should be received in 24-48 hours after the laboratory receives it.

Need both Antibody and Antigen tests? Click here

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.  

Please read the FAQs on PCR tests here

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 Antibody and PCR COVID-19 as home testing services.

You can take an antibody test from 14 days after the onset of your symptoms.

We work with a number of UK based Laboratories. Swab availability, capacity and turn around times will determine which ones we use on a daily basis. We only use laboratories with the highest accreditation standards, such as UKAS approved laboratories accredited to ISO 15189.

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. Read more about result interpretation here

We strongly advise:

  1. Nothing can go in the mouth for at least 2 hours prior to testing, this includes: food, drinks, cigarettes, chewing gum, etc.
  2. Mouthwash not to be used for 24 hours.
  3. Nothing can go in the nose for at least 24 hours prior to testing, this includes: nasal medication, saline, hay fever sprays, cotton buds, etc.

All of the above can inhibit the sample and mean they it needs to be retested or may not enable a conclusive result to be delivered.
