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 swab-based PCR test that checks for a current SARS-CoV-2 infection, for adults with symptoms or a recent contact who want a home test kit rather than a clinic visit.
1 biomarker as listed by LloydsPharmacy Online Doctor.
This test uses a nose and throat swab to check for a current SARS-CoV-2 infection, the virus that causes COVID-19. It is aimed at adults aged 18 and over with symptoms, such as a high temperature, a new continuous cough or a change to taste or smell, or anyone who has been in contact with someone who has the virus. The provider states the kit is CE-marked and legal to supply in the UK, and that only one kit can be ordered per person at a time.
We do not have named peer tests to compare this one against directly. Within the broader set of immunity tests we track, its single biomarker places it in the 36th percentile by depth, and its £73.70 price sits below the £144.25 median for similarly sized immunity tests, a 49% saving against that benchmark, though it costs more than this provider's own antibody test.
The score is supported by clarity and documentation and by value for money against the broader benchmark, though less strongly than the antibody test given the higher price. It loses marks on results and follow-up, since results are not reviewed by a doctor as standard.
This suits adults with COVID-19 symptoms, or who have been in contact with someone who has the virus, and want a home swab test rather than visiting a test site. It is not intended for outbound travel testing, since the provider does not guarantee results within 72 hours.
We do not track named peer PCR tests to point you to a cheaper or deeper alternative.
