Measures prolactin, a pituitary hormone linked to symptoms such as irregular periods, low sex drive and unexplained breast milk production. Suits anyone with these symptoms who wants a quick, single-marker check without a full hormone panel.
1 biomarker as listed by Better2Know.
Prolactin is a hormone produced by the pituitary gland. Levels can rise for reasons including pregnancy, and persistently high readings are also linked to pituitary conditions such as prolactinoma. This test measures prolactin alone, which the fact sheet notes is exactly what it sets out to do, so clinical depth is not really the point of a single-marker test like this.
Against the other prolactin tests we compare it with, this kit sits in the middle of the market. Medichecks offers the same single marker for £45, Blue Horizon Medicals charges £64.25, and Better2Know's own clinic-based version costs £135 for an identical marker. At £55, against a group median of £59.63, this home kit comes in slightly below average on price.
The listing scores well for clarity, since it publishes a full description, the sample type, collection options and a stated turnaround. Collection is also straightforward: you can do it at home with a finger-prick kit, or opt for the venous clinic version. It scores less well on results and follow-up because results are not reviewed by a doctor as standard, though Better2Know's own materials say a private doctor consultation can be arranged if your result comes back high. Better2Know has a Trustpilot score of 4.2 from 775 reviews, is CQC registered, and has been trading since 2008.
This test suits anyone who wants to check prolactin on its own, for example if you have symptoms such as irregular periods, reduced sex drive, erectile dysfunction or unexplained breast milk production, without paying for a broader hormone panel. It's worth discussing symptoms like these with a GP as well as testing prolactin on its own. The home finger-prick format also suits anyone who would rather avoid a clinic visit.
If price is the main concern, Medichecks' Prolactin Blood Test covers the same single marker for £45, £10 less than this kit. If you would prefer a venous blood draw instead of a finger-prick sample, Better2Know's own clinic-based Prolactin Test measures the same marker, though at a higher £135.
You take a finger-prick blood sample at home and post it to the lab, or choose the clinic-based venous draw for £135 instead. Once your sample arrives at the lab it is analysed, with results typically available within one working day. You view your results in a secure online patient area; the provider's own materials state that a private doctor consultation can be arranged if your result needs discussing, though the fact sheet does not state that a doctor reviews every result as standard.
This home finger-prick test checks prolactin alone, priced at £55 against a group median of around £60. It undercuts Better2Know's own £135 clinic version and Blue Horizon's £64.25 test, though Medichecks offers the same single marker for £45. The main caveat is that results are not reviewed by a doctor as standard.
