A vitamin D test checks how much vitamin D is in your blood to ensure your body has enough to function properly. Vitamin D is important for keeping your bones and teeth healthy. It also supports your muscles, nerves, and immune system to work normally.
Do you suspect a vitamin D deficiency? A discreet assessment using a vitamin D blood test can be highly beneficial. It can detect deficiencies at an early stage or ensure that your body has a sufficient supply of vitamin D for optimal health. Additionally, it helps diagnose related deficiencies, review treatment efficacy, and identify potential warnings early on.

What does a Vitamin D Blood Test in London involve?
- 25-Hydroxyvitamin D Test - This checks the level of 25-hydroxyvitamin D in the blood to assess vitamin D levels accurately. It should range from 20-50 nanograms per millilitre (ng/mL). A level lower than 20 ng/mL indicates deficiency, while a level higher than 50 ng/mL may indicate excessive vitamin D.
- 1,25-Dihydroxyvitamin D Test - This measures the active form of vitamin D in the blood. Abnormal levels may suggest issues with vitamin D metabolism, parathyroid hormone levels, or kidney function. The normal range is between 18-72 picograms per millilitre (pg/mL).
Additional Tests
- Calcium Levels - This measures calcium levels to assess the impact of vitamin D on bone health.
- Parathyroid Hormone (PTH) - This test ensures the proper functioning of the parathyroid glands, which maintain vitamin D and calcium balance in the blood.
