A Coronavirus 19 PCR (polymerise chain reaction) test is a swab test that detects the presence of the genetic material in coronavirus called RNA, indicating a current covid-19 infection. This throat swab test can be performed by an individual on themselves or by a healthcare professional. The sample is then analysed at an accredited laboratory and results are available within 48 hours of the sample being received by the laboratory.

There are many instances in which it may be appropriate to take a Coronavirus PCR test. This could be because a person is returning to work or education or visiting family members and want to make sure it is safe to do so. Or they may be returning to work and need to confirm they do not have a current infection.
The swab sample is taken by carefully inserting the swab into the back of the throat and rubbing it side-to-side across the tonsils and back of the mouth, then inserting it into the nose horizontally and rotating 5 times and waiting for 5-10 seconds before removing. Detailed instructions on how to take your swab sample are provided with the sample collection kit.
Results are usually available within 48 hours of the sample being received by the laboratory, although this turnaround time is not guaranteed.
The sample is stable in the post for up to 7 days.
Coronavirus PCR tests rarely fail. Failures usually occur if the swab does not contact enough of the nose or throat lining to pick up an RNA sample, or if the sample is not labelled or properly prepared for transit through the post.
The test is highly accurate providing the swab sample is taken well and has genetic material from the virus on it. The test detects 100% of samples known to contain the virus in laboratory testing. How well a swab is taken varies, and this can affect the accuracy of the test. Here is our video on how to take a swab sample to ensure an accurate result.
No, a positive result does not mean a person has immunity to COVID-19. A positive result will indicate that they have a current COVID-19 infection. A Coronavirus Antibody Test will confirm whether they have antibodies present in the body as the result of a previous COVID-19 infection. However, we do not yet know whether the presence of antibodies to SARS-CoV-2 in the blood provides any lasting immunity or protection from future infection.
This test will confirm whether or not someone has a current COVID-19 infection, but we cannot guarantee results will be delivered before their date of departure – particularly if they need to take the test within a few days of travel. We do not provide certificates indicating fitness to travel with this test.
Coronavirus PCR Swab Test result FAQs
The result will show either that COVID-19 RNA is ‘detected’ or ‘not detected’.
A positive result means that the genetic material in coronavirus (RNA) has been detected in the body, indicating a current COVID-19 infection.
A negative result means that RNA has not been detected in the body, and therefore there is not a current COVID-19 infection.
All Coronavirus PCR tests might give a negative result in someone who has a current COVID-19 infection. This is because the PCR swab must make contact with the virus – so if the body is not shedding the virus in the nose or throat, or if the swab misses the area with the virus, a negative result will be returned. This can affect up to 30% of people who have the infection and take the test. This issue affects all coronavirus PCR tests including those from other providers (including the NHS).
Our laboratory is required to inform Public Health England of all positive coronavirus PCR results in accordance with the Health Protection (Notification) Regulations 2010. This requirement covers a range of notifiable infectious diseases that can have serious consequences for public health, including COVID-19. Public Health England may ask Medichecks to provide the contact details of the person who had the test to contact them to arrange testing of people that they have been in contact with.
