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.
At-home urine PCR test for Zika virus, aimed at checking a suspected exposure within the last week. Suited to people trying to conceive who may have been bitten by a mosquito recently.
1 biomarker as listed by Better2Know.
This kit looks for Zika virus by PCR from a urine sample, which the provider positions for a suspected exposure in the last seven days, when the virus itself, rather than the antibodies it triggers, is more likely to be detectable. It is a particular concern for anyone pregnant or trying to conceive, since Zika can pass from a pregnant person to a foetus. It measures a single marker.
There is no comparison group of directly equivalent tests in our data, so we cannot check it against named peers. Against the wider set of immunity tests we track, its £399 price is well above the typical cost for a test of this size, which is the main driver of its low value for money score.
It scores reasonably well for collection convenience, since it can be done at home as well as at a clinic, and well for clarity, since the marker, sample type and turnaround are clearly stated. It scores poorly for results and follow-up, since results are not reviewed by a doctor as standard.
This suits someone who thinks they were bitten by a mosquito carrying Zika within the last week and wants to check before deciding whether to continue trying to conceive. If your possible exposure was more than two weeks ago, the provider's blood antibody test is aimed at that later window instead.
There is no equivalent test in our data to compare this against on price or depth, so we cannot say whether it is cheaper or more thorough than alternatives elsewhere.
You collect a urine sample at home using the kit provided and post it to the laboratory, or have the sample taken at a Better2Know clinic for £495. Results are uploaded to your online Patient Area within around 14 days and you are notified by email or SMS. The listing does not describe results as reviewed by a doctor as standard, though it states a doctor consultation is arranged if you test positive.
