VITAMIN D 25-HYDROXY TEST (25 OH D)
WHAT IS THE PRICE OF A VITAMIN D TEST?
HOW LONG WILL IT TAKE TO GET MY LAB TEST RESULTS?
Test results generally take between 24 to 72 business hours after your specimen is collected.
Vitamin D is a fat soluble vitamin that interacts with and regulates more than 200 genes in the body. Your body absorbs Vitamin D from exposure to sunlight or ultraviolet light on exposed skin, and from plants, fortified foods and supplements.
WHY DO I NEED A VITAMIN D LAB TEST?
Low levels of Vitamin D are associated with a significant increased risk for coronary artery disease, peripheral arterial disease, stroke, diabetes mellitus, and many causes of mortality.
Low, or abnormal results can sometimes be associated with inadequate sun exposure, air pollution, smoking, decreased fat intake, obesity, malabsorption problems, renal and liver diseases, corticosteroids, anticonvulsants, anti-rejection medications and/or HIV medications.
