Vitamin B12 and Vitamin D Blood Test
A vitamin B12 and vitamin D blood test measuring two nutrients linked to energy, nerves, bones and muscles. It suits vegans, vegetarians and anyone who spends little time outdoors.
What this test is for
This vitamin B12 and vitamin D blood test measures two vitamins shaped by diet and daylight. Total B12 shows all the vitamin B12 in your blood, which you need for red blood cells and nerves. Vitamin D is measured in the form that shows your stores, and supports bones and muscles.
Vegans and vegetarians often choose it, since B12 comes mainly from animal foods. It also suits people who get little sun or have darker skin, and anyone checking a supplement. You can use a finger prick kit at home or visit our Hull clinic.
Your report shows both levels against their reference ranges. A low result can prompt a look at diet, daylight or supplements, a repeat test, or a talk with your GP. For folate and active B12 too, see our Vitamin B12, Folate and Vitamin D Blood Test.
