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 checking for Hepatitis A, aimed at people who may have been exposed through sexual contact, contaminated food or water, rather than checking vaccination immunity.
1 biomarker as listed by Better2Know.
Hepatitis A can be transmitted through anal sex or anal play, or by consuming food or water contaminated by an infected person, and this test is aimed at people who think they may have been exposed rather than at checking long-standing immunity. A single blood sample is taken and analysed for the virus.
Better2Know does not list a wider comparison group for this test, so it cannot be checked against named rivals directly. It tests a single marker specifically aimed at detecting a current infection.
It scores moderately for collection convenience, since a home nurse visit is offered as an alternative to a clinic appointment, with results back within a day. It loses marks for results and follow-up because the initial result itself is not reviewed by a doctor as standard, although Better2Know's own description says a doctor's consultation is included if you test positive.
This suits someone who thinks they may have been exposed to Hepatitis A, for example through a relevant sexual contact or from food or water, and wants to check for the infection directly.
Because this test is not part of a listed comparison group, there is no specific cheaper or deeper alternative from the sheet to point to here.
A clinician takes a venous blood sample at a clinic, or during a paid home nurse visit, and sends it to the lab. Results are back within a day of the sample arriving. Better2Know's own description says a doctor's consultation is included if you test positive, though the initial result is not shown as doctor-reviewed as standard.
This test checks for Hepatitis A in people concerned about a possible infection, for example after a relevant exposure, rather than checking vaccination immunity status. Better2Know does not list a comparison group for this £145 test, and the package includes a doctor consultation if you test positive. The initial result itself is not reviewed by a doctor as standard.
