Getting enough of the Sunshine Vitamin? Request A Test offers this convenient and affordable Vitamin D2 and D3 Blood Test in Spring Branch, TX. This test, also known as the Vitamin D 25-Hydroxy Fractionated test, measures total Vitamin D and the two main forms of Vitamin D, D2 and D3. A standard Vitamin D 25-Hydroxy blood test that just measures total Vitamin D levels is also available. Vitamin D typically derives from two sources. D3 (cholecalciferol) is produced by the body when the skin is exposed to sunlight. For many people, D3 makes up the majority of the vitamin D in their body. D2 (ergocalciferol) is found in certain foods as well as vitamins and supplements. This test provides quantitative or numeric readings of D2, D3 and the combined total. The standard Vitamin 25-Hydroxy only provides the total or combined measurement of D2 and D3.
