A single-marker blood test for sex hormone binding globulin, used to help explain symptoms linked to a testosterone or oestrogen imbalance in men and women.
1 biomarker as listed by Better2Know.
This kit measures Sex Hormone Binding Globulin (SHBG), a liver-produced protein that binds testosterone and oestrogen in the blood and controls how much of each hormone is available to the body. In men, SHBG results can help explain reduced sex drive or erectile dysfunction. In women, changes in SHBG linked to higher free testosterone can show up as irregular periods, acne or excess hair growth.
Within the SHBG comparison group, this home kit is the most expensive way to get the same single result. Better2Know's own clinic-based version covers identical ground for £175, and Blue Horizon Medicals offers the same marker for £45.25. The only thing that changes between the three is where the sample is taken.
The scores reflect a clearly listed, single-purpose test that is easy to book from home, held back mainly by price relative to its peers and by the lack of doctor review as standard. Trust reflects Better2Know's Trustpilot rating of 4.2 from 775 reviews, CQC registration and 18 years trading.
This suits someone who wants to test SHBG without visiting a clinic, for example if symptoms such as low libido, erectile dysfunction, irregular periods or unexplained hair growth have already pointed towards a hormone imbalance. If cost is the priority and a clinic visit is not a barrier, Better2Know's own clinic-based SHBG test covers the same marker for £175, and Blue Horizon Medicals offers it for £45.25.
You take a finger-prick blood sample at home using the kit provided and post it to the laboratory (a venous draw at a clinic or nurse visit is also offered for £175). Results are reported within one working day of the sample reaching the lab. Results are not doctor-reviewed as standard, though Better2Know can arrange a private consultation to discuss them.
This home finger-prick kit measures SHBG alone for £195, the most expensive of the three SHBG tests we compare. Better2Know's own clinic version costs £175 for the same marker, and Blue Horizon Medicals charges £45.25. The only advantage here is not having to visit a clinic, and results are not doctor-reviewed as standard.
