About this test

Vitamin D helps regulate calcium and phosphate levels and supports bone and muscle health, and a blood test measuring Vitamin D (25-OH) is commonly used to assess whether your level is low, adequate or high.

At £65, this is the most expensive single Vitamin D test in our comparison group. Other providers charge considerably less for the same marker, including Monitor My Health (£38), Medichecks (£39), YorkTest (£41), Randox Health (£46), London Medical Laboratory (£49) and Forth (£50), with MyHealthChecked's rapid test at just £8.

value for money is the weakest part of the score here, sitting 33% above the £49 group median, while clarity and trust signals score well thanks to a detailed listing and a lab that is UKAS ISO 15189 accredited and CQC registered. It also loses marks on collection convenience, because it needs an in-person venous draw, and on results and follow-up, since there is no doctor review as standard.

Who is it for?

This suits anyone who specifically wants to test their Vitamin D level while attending a Bluecrest venue in person, for example alongside another health check booked there. On price, every other provider we compare charges less for the same single marker, from Medichecks and Monitor My Health at around £38 to £39 up to Forth at £50, so if cost is the main factor, Bluecrest is not the cheapest way to check Vitamin D. Anyone with symptoms of deficiency, such as persistent fatigue or muscle weakness, should also speak to a GP.

How it works

You attend a Bluecrest venue for a venous blood draw; there is no at-home kit for this test. The sample is sent to Bluecrest's own UKAS ISO 15189 accredited laboratory to measure Vitamin D (25-OH), with results typically back within 3 to 8 days. Results are not reviewed by a doctor as standard.
