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 home swab test for Group B Streptococcus, combining a rectal and vaginal swab, usually taken in the final weeks of pregnancy ahead of birth.
1 biomarker as listed by Better2Know.
Group B Streptococcus (GBS) can be passed from mother to baby during childbirth, and testing in the final weeks of pregnancy helps inform decisions around the birth. This version has you take both a rectal and a vaginal swab yourself at home and post them to the lab, rather than attending a clinic.
Better2Know does not list a wider comparison group for this test, so there is no named rival to check it against directly. It is £105 cheaper than Better2Know's own clinic-based version of the same test, which costs £175.
It scores well for collection convenience, since it is a home kit with results back within three days, or a clinic option for £175 if you would rather have the swabs taken for you. It scores lower for results and follow-up because results are not reviewed by a doctor as standard.
This suits someone approaching the final weeks of pregnancy who is comfortable taking both swabs themselves and wants to avoid a clinic appointment.
If you would rather have a clinician or nurse take the samples, Better2Know's own clinic version of this test is available for £175, though it is not doctor-reviewed as standard either.
You take a rectal swab and a vaginal swab at home and post both to the lab, with results back within three days. A clinic appointment is also available for £175 if you would prefer someone to take the samples. The fact sheet does not show results being reviewed by a doctor as standard, and Better2Know's own guidance says a positive result should be reported to your midwife directly.
This kit combines a rectal and vaginal swab, taken at home and posted to the lab, to check for Group B Streptococcus. At £70 it costs £105 less than Better2Know's own clinic version of the same test. Results are not reviewed by a doctor as standard.
