Coronavirus Antibody Blood Test

Checks for two SARS-CoV-2 antibody markers to indicate past infection or vaccination. Suits people wanting to check their antibody status, not as proof of current protection.

About this test

This test measures two antibody markers linked to prior SARS-CoV-2 exposure, one qualitative result and one from a specific assay (Roche). Antibodies can indicate the immune system has responded to the virus, through infection or vaccination, but their presence does not guarantee ongoing protection against reinfection, as the provider itself notes.

There is no comparison group of similarly named Covid antibody tests in our data, so this test cannot be benchmarked against named peers. Among the 88 similarly sized immunity tests we track more broadly, though, its £69 price sits well below the roughly £125 median.

Clinical depth is strong for a two-marker test relative to comparably sized immunity tests; value for money scores highly given the below-typical price; collection convenience is solid, with an at-home finger-prick collection and results back in 2 days; trust signals and results and follow-up reflect Medichecks' standard facts: a Trustpilot rating of 4.5 from 2,477 reviews, UKAS ISO 15189 accredited partner labs, doctor review included as standard, and 25 years trading since 2001.

Who is it for?

This suits anyone who wants to check whether they have developed antibodies after a past infection or a Covid-19 vaccination. There are no directly comparable named tests in our data, so we cannot say whether a specific peer would be cheaper or broader. It is not a way to confirm you are currently protected against infection; speak to your GP if you have symptoms or specific health concerns.

How it works

You provide an at-home finger-prick blood sample. The fact sheet does not detail further lab processing beyond the two antibody markers measured. Results are back within 2 days, and every test comes with a doctor's review as standard.

Pros & cons

Pros

  • Two antibody markers checked in a single test.
  • At £69, well below the roughly £125 median for similarly sized immunity tests we track.
  • Simple at-home finger-prick collection.
  • Results back in 2 days with a doctor's review.

Cons

  • Antibody presence does not guarantee protection against reinfection, as the provider itself notes.
  • No directly comparable named tests in our data to check this price against.
  • The provider does not state what the results report looks like.

Our editorial score

Compare Health Test Score Covid antibody check priced below typical immunity tests
Editorial confidence: 10.0/10

This £69 at-home finger-prick test checks for two SARS-CoV-2 antibody markers, which can indicate you have had a past infection or vaccination; it does not guarantee you are protected against catching Covid-19 again. At £69 it is well below the roughly £125 median for similarly sized immunity tests we track. Results are back in 2 days and reviewed by a doctor.
