A single blood test for sex hormone binding globulin (SHBG), a protein that carries sex hormones around the body and can be raised or lowered by a range of conditions and medications.
1 biomarker as listed by Blue Horizon Medicals.
Sex hormone binding globulin (SHBG) is a protein that binds to sex hormones such as testosterone and oestrogen and affects how much of them is available to the body. The provider notes SHBG can be raised by pregnancy, an overactive thyroid, cirrhosis, oral oestrogen and certain drugs, and lowered by testosterone, an underactive thyroid, Cushing's syndrome, acromegaly and obesity. Testing it in isolation gives you a single data point rather than a full picture of what is driving a result.
In its comparison group this is the cheapest option by some distance: £45.25 against £175 and £195 for the two Better2Know SHBG tests we track, for the same single marker. Collection is flexible, with an at-home finger-prick kit, a Tasso autodraw device, or a venous draw at a clinic or nurse home visit, and results are back within 1 day.
Value for money and collection convenience both score at the top of the range here, reflecting the low price against its named peers and the range of at-home and in-clinic collection options with a fast turnaround. Clinical depth scores solidly despite being a single marker, since depth is not really what this comparison group is testing for. Results are reviewed by a doctor, supporting the results and follow-up score, and clarity is helped by a listing that sets out the description, biomarker, sample type, turnaround and collection choices, though it does not describe the report format.
This suits you if you specifically want to check your SHBG level, for example alongside other hormone results, and want the fastest and cheapest route to that one number. Compared with the two Better2Know SHBG tests we track, at £175 and £195, this is markedly cheaper for the same single marker. It is not the right choice if you want SHBG interpreted alongside related hormones such as testosterone or oestradiol in one panel; for that you would need a broader hormone test.
You can collect your own sample at home with a finger-prick kit or a Tasso autodraw device, or have a venous blood sample taken at a clinic or by a home nurse visit. The sample is sent to the lab for SHBG analysis, and a doctor reviews the result before it is returned to you, typically within 1 day.
This SHBG blood test costs £45.25, less than a quarter of the price of the two Better2Know SHBG tests in its comparison group (£175 and £195). It can be done at home with a finger-prick or Tasso autodraw kit, or via a venous draw at a clinic or nurse home visit, with results back in 1 day. As a single-marker test it will not tell you why an SHBG result is high or low; that needs interpretation alongside other markers or symptoms.
The listing publishes a short description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
A single-marker test measuring exactly what it sets out to; depth is not the point of this comparison group.
A finger-prick sample you take at home; with a venous or clinic option as well; a home nurse visit is offered; results in around 1 days, in line with or faster than similar tests.
Results are reviewed by a doctor; the provider does not describe the report format.
