COVID-19 Antibody Test: Cost £195.00


Our COVID-19 antibody test can help identify if you have previously been exposed to COVID-19.

The COVID-19 Antibody test detects the presence of the SARSCoV-2 specific IgG and general IgM for the qualitative diagnosis of early and late stage COVID-19. As mentioned, IgG is specific to SARS-CoV-2 and confirms secondary illness (usually >7 days), whereas IgM confirms primary illness (3-7 days). Both are elevated in the secondary illness and can be used to confirm diagnosis.


A venous blood is taken, and the sample is sent to our partner laboratory for analysis with results provided the following day. All our tests are carried out by trained registered nurses in clinic.

What is IgM?

Immunoglobulin M (IgM) is the largest immunoglobulin in humans and is the first antibody to be produced upon infection. Since it has multiple antigen binding sites, it can be thought of as a ‘general’ antibody and is compatible with many pathogen species/types. In the case of COVID-19, IgM levels in the blood rise to a detectable level 3-7 days after infection, as symptoms begin to appear.

A positive result for specific-IgM antibodies is indicative of early phase primary COVID-19 infection. Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status, a follow-up testing with a molecular diagnostic (PCR) test should be considered to rule out infection in these individuals especially if exhibiting any symptoms.

What is IgG?

Immunoglobulin G (IgG) is a smaller structure and is produced in response to a specific antigen on the pathogen. Its levels rise later than IgM (>7 days) and indicates exposure to the SARS-CoV-2 sometime previously.

A positive result indicates previous exposure to SARS-COV-2, this antibody test is not a diagnostic tool for active infection. This test should be interpreted by a health care professional in the context of patient history and symptoms.
