Randox Rapid COVID-19 PCR Testing

Randox Rapid Covid-19 Coronavirus PCR Tests

Randox have partnered with DocTap to provide 3 hour and same day PCR testing from multiple clinics across London.

All our tests are taken at a medical facility, either as a guided self swab or by a healthcare professional and then taken to the laboratory by our in house couriers. For added peace of mind, patients receive regular email notifications throughout the testing process. All coronavirus PCR test results include both a Randox results certificate and accompanying doctor's letter. Our close partnership enables us to guarantee the timings for your results - or you will receive a full refund.

If you require a Covid-19 PCR test to reduce your requirement to self-isolate after arriving into England (Test to Release) then please ensure you have selected Test to Release on the booking page. Whilst they are the same type of PCR test, it will only be valid for the Test to Release scheme if you specifically book a Test to Release appointment.

test details and timings

PCR tests require a swab to be taken from the back of your throat and nose.  It can be a little uncomfortable but should not hurt.  This can either be a guided self swab or taken by a healthcare professional. Our 3 / 6 hour and same day tests only require a sample from the back of your throat, which some people may prefer. You can choose which you prefer when booking your test.

Antibody and Antigen tests will always be carried out by a healthcare professional.

Different airlines and countries have different requirements regarding when a test must be taken.  Many require a negative PCR test to have been carried out no more than 72 hours before a flight, but please check the government's foreign travel advice for your destination to establish their exact requirements. We have over 30 clinics across London offering same day and next day results.  We also have results in just 3 hours at our Healthrow Airport site.  You can select your preference when you book your test

Please be aware that a very small proportion of tests will return an inconclusive result and will require retesting, which we would arrange free of charge.  We do therefore advise you take your test as soon as permitted for your trip.  For instance, if you require a test taken not longer than 72 hours before your flight at 1pm on 10th May, the optimal time to take your test would be at approximately 2pm on 7th May.  

The majority of countries require a PCR test. We offer PCR tests with both same day and next day results. This is the gold standard of Covid-19 testing. A few countries will accept antigen lateral flow tests, but please check the requirements for your destination country.

Different countires and airlines have different policies and they are changing frequently.  To ensure that you have the most up to date information, please contact your airline or review the latest government's travel advice.

We can carry out PCR tests on young children. Some healthcare professionals will not be comfortable taking a swab from very young children as it can be stressful for the child if carried out by someone they do not know.  If this is the case they will be able to assist and guide the parent to take a swab from the child.

We are unable to carry out antigen tests on children under 5 years old. Children under 5 should have a PCR test.

Yes, all our test partners have confirmed that their sensitivity and specificity is unchanged with regards to the new Covid-19 strain in the UK.  They will not however differentiate between whether you have the "pre-existing" or novel strain.

If you require this please let us know once you have received your results.  Please allow an additional 24 hours to arrange printing and signing of your certificate.  We only have a limited number of London locations where you can collect a certificate from.  We will be able to advise you on your options depending on the day your results are available.

No. We are only able to issue doctor's certificates for tests which have been booked with DocTap. If you are in a hurry you can book a same day or 3 hour PCR test here and you will get a doctor's letter along with your results.

test to release

Test to Release is a government scheme to enable people arriving in the UK to reduce the amount of time for which they must self isolate.  The government have appointed DocTap as an official Test to Release provider.

Anyone who arrives in England from outside the UK, Ireland, the Channel Islands or the Isle of Man needs to self-isolate for 10 days.  Under the Test to Release scheme, you can choose to pay for a private Covid-19 test after you have been in England for 5 full days.  If the test result is negative then you can stop self-isolating immediately.

For instance, if you arrive in the UK on Monday then Tuesday would be your first full day in the UK, and you cannot take the test for Saturday. 

If you require Test to Release, then please ensure that you select Test to Release as an appointment type on the booking page or it will not be accepted by the goverment.

DocTap is an official provider for the government's Test to Release programme. If you wish to shorten the amount of time you need to self isolate then please visit our Test to Release page for details

Please note that our provision of Covid-19 coronavirus tests does not impact on NHS test availability, instead, by providing the tests at competitive prices compared with other providers, our service aims to work as a helpful adjunct to the NHS by increasing testing options in the community. We also report all positive results to Public Health England, and this is obligatory.

Important note: where patients are taking a self swab they must do as directed in the instructions provided.  Failure to take a swab as directed, or to take a swab on behalf of someone else is a gross breach of the terms of this service.
