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.
An at-home finger-prick blood test quantifying IgG and IgM Covid-19 antibodies from past infection or vaccination, giving a numerical antibody level you can track over time. Suits people who want to test without visiting a clinic.
1 biomarker as listed by Better2Know.
This test measures both IgG and IgM antibodies against the Covid-19 spike protein from an at-home finger-prick blood sample, giving a numerical antibody level rather than just a positive or negative result, so you can track how your antibody level changes over time following infection or vaccination. Because it targets the spike protein used in many Covid-19 vaccines, it can pick up a vaccine response as well as a prior infection.
We do not have a named comparison group for this specific test, but against the wider set of 79 similarly sized immunity tests we track, its £59.95 price is 58% below the £144.25 median, making it one of the more competitively priced tests of its kind that we track. Its single biomarker places it around the middle for depth among tests of this type, which is expected for a targeted antibody check rather than a broad panel.
It scores strongly for value for money given how far below the group median it sits, and well for collection convenience since it is done entirely at home with results back in about 2 days. It scores lower on results and follow-up because, as with Better2Know's other tests, results are not doctor-reviewed as standard.
This suits you if you want a low-cost, at-home way to check your Covid-19 antibody level, for example after vaccination or a past infection, without needing a clinic appointment.
We do not hold named peer tests in our data for this specific test, so we cannot point you to a cheaper or deeper named alternative. Better2Know separately lists a clinic-based version of this test if you would rather have a clinician take the sample in person.
You collect a finger-prick blood sample at home using the kit provided and post it to Better2Know's laboratory, which tests for both IgG and IgM antibodies against the Covid-19 spike protein. The fact sheet states results are available within about 1 working day of the sample's arrival, viewable in your online patient account, with notification by your preferred contact method. It does not state that results are doctor-reviewed as standard.
This at-home Covid-19 antibody kit costs £59.95, 58% below the £144.25 median for the 79 similarly sized immunity tests we track. Results come from a finger-prick sample posted to the lab and are ready within about 1 day. There are no named peer tests in our data for this exact test, and results are not doctor-reviewed as standard.
