What’s Included in this Package

Vitamin B12 and Folate Test

Vitamin B12 and folate support many cellular functions in the body. B12 supports nerve function, and folate (aka folic acid or vitamin B9) converts carbohydrates into energy and forms DNA. Both B12 and folate are essential to red blood cell production.

 

The Vitamin B12 and Folate Test measures levels of vitamin B12 and folate in your blood to help identify potential vitamin deficiencies. A B12 deficiency or a folate deficiency may lead to symptoms of fatigue, weakness or anemia.

  • Vitamin B12

    Vitamin B12 plays an essential role in red blood cell formation, cell metabolism, nerve function and more. It’s found in foods such as nutritional yeast, plant-based milks and certain cereals. When you’re deficient in vitamin B12, you may experience symptoms like fatigue, weight loss and loss of appetite. 

  • Folate

    A natural form of vitamin B9, folate helps your body make new red blood cells and DNA, and it plays an important role in a fetus’s development. It’s found in foods such as leafy greens, beans, seafood, eggs and more. When you’re deficient in folate, you may experience symptoms like fatigue and weight loss.

  • Vitamin D 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.

  • 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.
