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 blood test for Hepatitis A IgG antibodies, used to check for past infection and immunity to Hepatitis A; suited to anyone wanting to confirm their immunity status via a clinic or nurse-visit blood draw.
1 biomarker as listed by Blue Horizon Medicals.
This test looks for Hepatitis A IgG antibodies in a blood sample. The provider states that a positive result indicates a probable past infection and, in turn, long-term immunity to the virus.
Within the wider set of 79 similarly sized immunity and infection tests we track, its £89.25 price sits around 38% below the £144.25 median, giving it a strong value-for-money score, in line with the related Hepatitis A IgM test from the same provider. As a single-marker test it sits in the 36th percentile for clinical depth among immunity tests, which reflects its narrow focus rather than a lack of quality.
Clarity scores well here because the listing includes a short description of what the test checks alongside the full biomarker list, sample type and turnaround. Collection convenience is limited by the need for a venous blood draw at a clinic, though a nurse home visit is offered, and results and follow-up score well thanks to doctor review within 5 days.
This suits people who specifically want to confirm their Hepatitis A immunity status, for example after a past infection or vaccination, and who can attend a clinic or arrange a nurse home visit for the blood draw. A 5-day turnaround with doctor review makes it reasonably quick to act on.
It pairs closely with the provider's Hepatitis A IgM test if you want to check for both recent infection and immunity status, though ordering both would mean two separate venous samples rather than one combined test.
You have a venous blood sample taken, either at a clinic or via a nurse home visit. The lab checks for Hepatitis A IgG antibodies, and a doctor reviews the result before you receive it. Turnaround is 5 days.
This blood test checks for Hepatitis A IgG antibodies to establish past infection and immunity status. It costs £89.25, around 38% below the £144.25 median for the 79 similarly sized immunity and infection tests we track, and includes doctor-reviewed results within 5 days. It requires a venous blood draw at a clinic or nurse visit rather than an at-home finger-prick.
