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.
Clinic-based urine PCR test for Zika virus, aimed at checking a suspected exposure within the last week. Suited to people who prefer a clinician to take the sample rather than self-collecting.
1 biomarker as listed by Better2Know.
This test looks for Zika virus by PCR from a urine sample taken at a clinic or during a home nurse visit, aimed at a suspected exposure within the last seven days, when the virus is more likely to be detectable than the antibodies it triggers. It is a particular concern for anyone pregnant or trying to conceive. It measures a single marker.
Better2Know also sells an at-home version of this same PCR urine test for £399, which uses a self-collected sample posted to the lab instead of a clinic or nurse visit; this clinic version costs £495. There is no comparison group of other providers' tests in our data, so we cannot benchmark it beyond this internal comparison, but against the wider set of immunity tests we track its price is well above the typical cost for a test of this size.
It scores well for collection convenience, since a home kit alternative and a nurse visit are both offered, 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 would rather have a clinician take the sample than collect it themselves. If you are comfortable self-collecting a urine sample, Better2Know's own at-home kit covers the same marker for £399, £96 less than this clinic version.
If your possible exposure was more than two weeks ago, the provider's blood antibody test is aimed at that later window instead.
A clinician gives you a container to provide a urine sample at a Better2Know clinic, or you can arrange a home nurse visit; the sample is then sent to the laboratory for analysis. 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.
Zika PCR (Urine) is the clinic-based version of Better2Know's Zika urine test, aimed at a suspected exposure within the last week, and costs £495, more than the at-home version of the same test at £399.
