Differences between COVID-19 tests?

10th November 2021 By Phoenix Hospital Group

COVID-19 tests are used to reduce the transmission of COVID-19, and to test for current infection of the virus. Furthermore, there are also tests that can measure the level of antibodies within your blood to determine whether you have been previously infected or if your COVID-19 vaccine produced protective antibodies. At Phoenix Hospital Group, we offer several COVID tests.

 

The tests we offer:

  • COVID-19 General PCR Test
  • COVID-19 Fit-to-fly PCR Test
  • COVID-19 Day 2 & 8 PCR Test
  • COVID-19 General Rapid Antigen Test
  • COVID-19 Rapid Antigen Day 2 (fully vaccinated)
  • COVID-19 Rapid Antigen Fit to Fly (EU countries)
  • COVID-19 Quantitative Antibody Test

 

COVID-19 General and Fit-to-fly PCR test

The General and Fit-to-Fly PCR test is a combined nose and throat swab test which determines whether you are currently infected with the COVID-19 virus.

The test is the accepted by most airlines and countries for arrival compliance. Results are normally sent within 24 hours.

 

COVID-19 Day 2 & 8 PCR test

The Day 2 & 8 PCR test determines whether you are currently infected with the COVID-19 virus and it’s a combined nose and throat swab test.

The Day 2 & 8 PCR test is a requirement if you are unvaccinated arriving in the United Kingdom from international destinations. A unique reference number for the passenger locator form is emailed directly to you after booking the test. Results are normally sent within 24 hours.

 

COVID-19 Rapid Antigen test

The rapid antigen COVID-19 test requires a nose and throat swab highlighting whether you are currently infected with the virus.

The test is approved Public Health England and is accepted by most EU countries for travel purposes.

Fully vaccinated passengers arriving in England from countries not on the red list can now take this test, instead of a PCR test, on or before day 2 of their arrival into the UK. Results are normally sent within 2 hours.

 

COVID-19 IgG Antibody test

The IgG antibody test is a blood test collected by either a nurse or an at home test, for which you will need to provide a blood sample from a finger prick. This test is used to measure the level of antibodies within  your blood and show a unique response to the virus or the vaccine.

Antibodies are created by white blood cells to counteract viruses that enter the body, and work by recognising the specific proteins on the surface of viruses. Once you’ve recovered from an infection, or if you’ve received a vaccine, some of the immune cells that create antibodies are stored as memory cells which then provide the body with the means to much more quickly fight off any future infection by the same virus.

The IgG antibody test is measured on a scale. If the result is below ’50 U/ml’, the test shows that you have no antibodies in your sample, and it’s likely that you either haven’t had COVID-19 or the vaccine, or you have just experienced very mild or non-existent symptoms of COVID-19. If the result comes back above 50 U/ml, it suggests that COVID-19 antibodies have been produced, meaning that that the likelihood of having been previously infected by the virus is high. The higher the number, the greater the level of protective antibodies. Results are normally sent within 4 hours.
