About this test

This test determines which of the four main blood groups, A, B, AB or O, you belong to, and whether your red blood cells carry the RhD antigen, making you Rhesus positive or negative. Between the two systems there are eight possible blood group and Rhesus combinations, and the result is a straightforward, one-off piece of information rather than something that changes over time.

We do not have a directly comparable rival test on file for blood grouping specifically, so we cannot say how this compares on price. Set against the wider group of general wellness tests we track, it is priced modestly above the typical rate, at 11% over the median for a test of this size.

The test scores well for clarity, with the sample type, turnaround and what it covers all clearly published, and moderately for collection convenience, since a home nurse visit is offered alongside the clinic draw. It scores lower on clinical depth, as it reports a single, fixed result rather than a range of biomarkers, and on results and follow-up, since a doctor does not review the outcome as standard.

Who is it for?

This suits you if you want your blood group and Rhesus status on record, for example ahead of donating blood, or simply to know your own type in case it is ever needed in a medical emergency. It's a one-off piece of information rather than something you would need to repeat.

We do not have a directly comparable test from another provider on file, so if cost is the main factor, it's worth checking whether your GP practice or a blood donation service can provide this information at lower cost before paying privately.

How it works

A qualified medical professional takes a venous blood sample at a clinic, or you can arrange a home nurse visit, and the sample is sent to Better2Know's laboratory for analysis. Results, which state your ABO group and RhD status, are ready within two days, and you are notified by phone, email or text; the provider does not state that a doctor reviews the result as standard.
