Discover your vitamin D levels with a vitamin D blood test

Vitamin D is both a nutrient you eat as well as a hormone that's produced by your skin in response to sunlight exposure. It plays a significant role in bone health by helping regulate calcium and phosphorus, which are essential minerals that work together to build strong bones. Vitamin D also has a role in your nerve, muscle and immune systems, as well as your mental health. 

This vitamin D blood test evaluates 25-hydroxyvitamin D (25-D): the best measure of how much vitamin D is stored in your body. A prolonged deficiency in vitamin D has been shown to lead to fatigue, bone pain and even depression.  

Discover your nutritional status with the Micronutrient Test. Measure essential vitamins and minerals like vitamin D, B12, folate, magnesium, iodine and zinc to get a bigger picture of your health.

What's Tested
  • Vitamin D

    Labcorp OnDemand’s Vitamin D Test measures the level of 25-hydroxy vitamin D in your blood. Vitamin D helps your body regulate calcium metabolism which in turn helps maintain healthy bones, control infections, reduce inflammation and more. Your skin produces vitamin D through sunlight exposure. Vitamin D is also found in foods such as fatty fish, mushrooms, egg yolks and fortified milks. When you’re deficient in vitamin D, you may experience symptoms like fatigue, muscle weakness and depression. Additionally, you could become more prone to having fractures from falls if you have a vitamin D deficiency.
