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.
Semen sample PCR test for Zika virus, aimed at men who may have been exposed within the last week and are planning to conceive with a partner.
1 biomarker as listed by Better2Know.
This test looks for Zika virus by PCR in a semen sample, aimed at men who may have been bitten by a mosquito carrying Zika within the last seven days and who are planning to have children, since Zika can be transmitted to a partner and pass to a foetus during pregnancy. It measures a single marker and is one of several sample types Better2Know offers for Zika testing, alongside blood and urine versions.
There is no comparison group of directly equivalent tests in our data, so we cannot benchmark it against named peers. Against the wider set of immunity tests we track, its £795 price is well above the typical cost for a test of this size, which is the main factor behind its very low value for money score.
The listing scores 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, though a doctor consultation is arranged if you test positive.
This suits a man who thinks he may have been bitten by a mosquito carrying Zika within the last week and is planning to conceive with a partner, where a semen sample is the relevant one to test. If a urine or blood sample is more practical for you, Better2Know also offers Zika PCR urine tests and a Zika antibody blood test, at lower prices than this semen version.
There is no equivalent semen test from another provider in our data, so we cannot say whether this is priced competitively against the wider market.
A clinician provides you with a container to give a semen sample in a private bathroom at a Better2Know clinic, and the sample is 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.
