A single blood test measuring total vitamin D (D2 and D3 combined), used to check for deficiency or to monitor supplementation.
1 biomarker as listed by Monitor My Health.
Vitamin D is a hormone that helps regulate calcium and phosphate levels and supports healthy bones, teeth and muscles. This test measures both forms, D2 (from plants and supplements) and D3 (made in skin from sunlight or taken as a supplement), reporting the combined total.
Within our eight-test vitamin D comparison group, its £38 price is below the £49 median, though MyHealthChecked's Vitamin D Rapid Test is notably cheaper at £8; the fact sheet does not detail how the two tests compare beyond price. Against the remaining peers, from Medichecks (£39) up to Blue Horizon Medicals (£53.25), all testing the same single marker, this test sits toward the cheaper end.
Scores here are led by value for money and by the trust and process factors common across Monitor My Health's range, with a doctor reviewing every result and providing guidance on supplementation where relevant.
This suits anyone who wants to check their vitamin D level, including people at higher risk of deficiency such as those who spend little time outdoors, have darker skin, are pregnant or breastfeeding, or have a condition affecting absorption. If price is the only consideration, MyHealthChecked's Vitamin D Rapid Test is considerably cheaper at £8, though we do not have details on how it compares beyond price.
You take a finger-prick blood sample at home, with no need to stop vitamin D supplements beforehand, and post it Monday to Thursday. Results are typically available within 1 to 2 days and reviewed by a doctor, who explains whether your level is deficient, insufficient, adequate or optimal.
Priced at £38, this sits below the £49 median of our eight-test vitamin D comparison group, though MyHealthChecked's Vitamin D Rapid Test is considerably cheaper at £8. All peers test the same single vitamin D marker.
