Immune System Blood Test
Highly rated for depth and priced well below the market
An 8-marker blood test covering white and red blood cells, vitamin D, B12, iron status and inflammation, for a broad check of immune-related health.
A combined blood test measuring both nucleocapsid antibodies, which indicate past infection, and spike protein antibodies, which indicate a vaccine or infection response.
2 biomarkers as listed by Monitor My Health.
This bundle runs two tests on one blood sample: a check for SARS-CoV-2 nucleocapsid (N) antibodies, which indicates a past COVID-19 infection, and a check for spike protein (S) antibodies, which indicates an immune response to either vaccination or infection. The provider is explicit that a positive result does not mean you are immune to the virus, and that neither test can confirm a current infection or serve as proof for international travel.
We do not track a comparison group of similar bundled tests for this product, so no relative price or depth claim is made here. Taken on its own, buying this combined test costs £17 less than ordering Monitor My Health's standalone Antibody Test (£39) and Vaccine Immunity Test (£42) separately.
The scores reflect strong trust signals, thanks to Monitor My Health's Trustpilot rating and its CQC-registered, UKAS ISO 15189 accredited lab, and a doctor review on every result. The most important thing to weigh up is timing rather than the score: the provider says this test will no longer be available after 30 September 2026, and samples must reach the lab by then to be processed.
This suits anyone who wants to check both for a past COVID-19 infection and for antibodies from vaccination or infection in a single test, and who can act quickly, since Monitor My Health says the test will not be available after 30 September 2026 and will not process samples that arrive after that date. If you only need one half of this bundle, the standalone Antibody Test (£39) or Vaccine Immunity Test (£42) are cheaper on their own.
You take a finger-prick blood sample at home and post it Monday to Thursday. The lab runs the Roche Anti-SARS-CoV-2 test for nucleocapsid antibodies and the Roche Anti-SARS-CoV-2 S test for spike protein antibodies on the same sample. Results are typically available within 1 to 2 days and are reviewed by a doctor before being shown to you on the website.
This £64 bundle combines Monitor My Health's separate antibody and vaccine immunity tests, which would cost £81 bought individually, a £17 saving. There is no comparison-group data for this test, and the provider states it will stop offering it after 30 September 2026.
