About the Vitamin D test
Vitamin D is a fat-soluble vitamin. It is also known as the ‘sunshine vitamin’ because we produce most of what we need through exposure to the sun.
This vitamin controls absorption of calcium and phosphate by the body and is vital for keeping your bones and teeth healthy. That’s why it is particularly important for pregnant women, breast-fed babies and children under 5 to produce enough vitamin D.
Having a deficiency is very common, especially in the winter months when sun exposure is reduced. However, if you’re over 65, have dark skin or suffer from inflammatory bowel disease or other fat malabsorption conditions you may be more prone to vitamin D deficiency.
Who is the test for?
This test is for anyone who would like to establish whether they have a vitamin D deficiency. It may be especially useful for pregnant women, people over 65, with black or Asian skin types or people with gut, liver or kidney diseases.
