If you’re lacking in vitamin D, you’re not alone—about 35% of American adults don’t get enough of this essential vitamin. That’s partly because vitamin D can only be produced by the body when it synthesizes the sun’s rays through the skin, or when you consume foods or supplements with vitamin D. So if you don’t get enough sun exposure or eat a diet lacking in the right foods, you may be missing out on vitamin D. And a deficiency can be serious because you need vitamin D for bone, nerve, and muscle health. That’s why you want to check your vitamin D 25-hydroxy levels.
The test measures your levels of vitamin D 25-hydroxy, which is the form of vitamin D after it’s been processed by your liver.
Testing may be advised if you:
You don’t have to take any special steps before a 25-hydroxy vitamin D blood test.
Vitamin D hydroxy-25 levels can range from 20 to 50 nanograms per milliliter (ng/mL), depending on the test, to be considered normal. If your levels are too low, you may need to consider adding supplements or vitamin D-rich foods such as eggs, fish, or fortified milk to your daily diet. If you need guidance or support, you can talk with one of our board-certified physicians during a telehealth appointment.
With more than 400 tests in our online store and more than 4,000 labs across the country to choose from, it couldn’t be easier to get a 25-hydroxy vitamin D test. Trust Personalabs to deliver the power of healthcare and put it in your hands.
