COVID-19

How can we test for COVID-19?

Nasal and throat swab using PCR [polymerase chain reaction] testing:

What does the test tell me?
This test tries to establish whether you are currently suffering from COVID-19.

What does it involve?
A deep swab from one or both nostrils and a thorough swab from the throat is needed.

How reliable is the test?
It is estimated the test has a 60-80% chance of picking up the Coronavirus [SARS-CoV-2] causing COVID-19.

As it detects a certain part of the virus, it is possible that it picks up remnants of a dead virus, which is no longer infectious to others. This means you have a false positive result and you are told you are infectious when you are not. However, it still tells you that you had the virus in your upper respiratory tract.

How soon do I get the result?
Results can be back in 10 minutes (fast tests) or 1-3 days (laboratory tests).

How much does it cost?

Where can I have this test?
NHS – test and trace for free

Blood test for IgG to Coronavirus causing COVID-19:

What does the test tell me?
This test tells you whether you previously (>7-14 days ago) had COVID-19.

New evidence suggests that your IgG level may decline over time and may become negative again. This can occur over weeks or months after a positive test. However, it is not yet clear whether your immunity to SARS-CoV-2 [virus causing COVID-19] also has completely vanished or whether there are still other mechanisms in your body to protect you to some degree or even completely from a re-infection.

What does it involve?
A blood test with a needle and a specimen bottle or a finger prick test.

How reliable is the test?
Full blood test:
The normal blood test picks up 97.5% of COVID-19 cases. If the test is positive it is definitely (100%) due to SARS-CoV-2 [virus causing COVID-19] {Sensitivity 97.5% and Specificity 100%}.

Finger prick test:
The finger prick test has been less reliable. It misses some positive cases and has been positive for other types of seasonal Coronavirus. Every finger prick test has a slightly different accuracy but no test has been accepted by Public Health England as of now.

How soon do I get the result?
Results are back in 10 minutes (finger prick test) or 1 day (laboratory tests).
