COVID Test Frequently Asked Questions

For more information go to the NHS covid-19 website. Do not visit a health centre.


What is a PCR Test?

A PCR test is a Polymerase Chain reaction test. This looks for the presence of genetic material (RNA fragments) from SARS-CoV-2 and is used to diagnose if you are currently infected with the virus.

Why should I take a PCR test?

Anyone can take a PCR test. Main reasons for seeking a test are:

  • Concern over exposure – If anyone is worried that they have been exposed to the virus they can take the PCR test, whether this is symptomatic or asymptomatic.
  • Concern for another – You may be in regular contact with a person who is particularly vulnerable to Covid-19 and want to check yourself for your own peace of mind.

If you have Covid-19 symptoms you must isolate to protect others.

How accurate is the PCR test?

When analysed by Public Health England and Hampshire Hospitals NHS Foundation Trust, our test correctly identified all positive and negative samples without exception.

How is the test carried out?

Your sample is sent to our UKAS-accredited laboratory and analysed by EM Analytical.

What does a positive result mean?

A positive result means you currently have the Corona Virus.

If your covid-19 PCR test is positive you and your household will need to isolate until you receive a negative test or until you complete the government-mandated isolation period.

What does an inconclusive result mean?

A small number of tests may return as inconclusive. This means it was not possible to determine if you had the virus at the time of giving the sample. Unfortunately, this means you will need to be tested again. We will either refund your test in full or arrange a new test kit.

Will the test tell me if I already had COVID-19?

No. A PCR test can tell you if you currently have the virus only.

What information will my Fit2Fly certificate contain?

Your fit to fly certificate will contain your name, date of birth, gender, passport number (optional), sample barcode number, sample type, date and time you collected your sample, date and time your sample was tested and a sign-off from our registered Doctor.

What is contained in the test kit?

In the test kit are:

Two swabs, two sample vials, instructions on how to collect your sample, instructions on how to return your sample, instructions on how to register your sample online and all the packaging required to return your sample.

How do I take the test - do I need to swab the back of my throat and nose?

We provide detailed instructions in each test sent. To collect a sample you will need to swab the back of your throat and just around the inside of your nose.

Can someone else help me to take the test if I am struggling to do it myself?

If great care is taken to reduce the risk of cross contamination then yes.

If you require assistance make sure you are comfortable, ensure the person assisting you washes their hands thoroughly, wears gloves while handling the swabs and wears a face mask during the whole process. Only once the sample has been placed in the vial and secured with a lid does the risk of cross contamination disappear.

Will I find taking the test painful/ does the swab hurt?

Taking your test may be uncomfortable, but this is only brief and should not cause you real pain.

How long does a covid test take?

Once we have received your sample at our lab we will have it processed within 6-8 hours.

What could I do wrong that would invalidate my test?

The major risk is cross-contamination. Beyond this ensuring everything is sealed correctly and handled delicately will reduce the risk of an invalid test.

When should I book my Test to Release Scheme test?

If you intend to use the Test to Release Scheme, you may need to provide evidence on entry to the UK that you have a test booked. For this reason we recommend purchasing your test in advance of your flight into the UK. We will send you an email with a confirmation of your booking to use as evidence.

How will I know if I have taken the test correctly?

If you make contact with the swab on the key areas noted in the instructions, this will ensure your test is performed correctly.

How quickly will I receive my results after I have posted the test back to you?

If you are able to drop your test at a Royal Mail priority drop box, we should recieve it the following day and will process it within 24 hours.

What should I do if the test comes back positive?

If your test comes back positive you must self isolate immediately and follow the government guidelines.

What happens if I contract the Coronavirus after I have completed the test?

If you begin to feel symptoms associated with Coronavirus, even if you have a negative test result, you must self isolate and seek another test to confirm if you have Coronavirus.

Do I receive a paper copy of the certificate or is it digital?

We will send you a digital copy of your certificate as standard, however if you wish to receive a paper copy we can also send this as next day delivery for a small fee.
