A single-marker blood test measuring vitamin D (25-OH), for checking levels linked to bone health, immune function and general wellbeing.
1 biomarker as listed by Forth.
Vitamin D is important for bone health, immune function and general wellbeing, and low levels are common, particularly with limited sun exposure. This test measures 25-OH vitamin D, the standard marker used to assess vitamin D status, on its own rather than as part of a wider panel.
Among the eight vitamin D tests we track, this sits right around the group median: £50 against £49. Cheaper options include MyHealthChecked's Vitamin D Rapid Test at £8, Monitor My Health at £38, and Medichecks at £39, while London Medical Laboratory matches Forth's price band at £49 and Blue Horizon Medicals is slightly higher at £53.25.
value for money is close to average, only 2% above the group median. Collection is flexible across four methods, and results are reviewed by a doctor within 2 days.
This suits you if you want a straightforward, doctor-reviewed vitamin D check with flexible collection options. If price is the only factor, Medichecks or London Medical Laboratory offer the same marker for less, and MyHealthChecked's Vitamin D Rapid Test costs as little as £8, though check whether it includes the same doctor review.
Collect your sample using an at-home finger-prick kit, Forth's AutoDraw device, a home nurse visit, or a venous draw at a partner clinic. The lab measures your 25-OH vitamin D level, and a doctor reviews the result before it is released to you. Results are typically available within 2 days.
At £50, this single-marker vitamin D test sits close to the £49 group median across the eight vitamin D tests we compare. Several peers, including Medichecks and London Medical Laboratory, offer the same marker for £39 to £49. It includes a doctor review and results in 2 days.
