Vitamin D Blood Test
A vitamin D blood test that shows how much vitamin D your body has stored. It suits anyone who gets little sun, covers up outdoors or takes a supplement.
What this test is for
This vitamin D blood test measures the main form of vitamin D in your blood, which shows how much your body has stored. Your skin makes it in sunlight, and small amounts come from oily fish and eggs. Vitamin D helps keep your bones, teeth and muscles strong.
It suits people who spend most of the day indoors, cover their skin outside or have darker skin. In UK winters the sun is too weak for skin to make much vitamin D, so late winter is a good time to check. You can use a finger prick kit at home or visit our Hull clinic.
Your report shows your level against the reference range. A low result can prompt a look at daylight, diet or supplements, and a repeat test a few months later shows what has changed.
