Vitamin D, 25 - HYDROXY (Vitamin D3)

Vitamin D enables your body to retain calcium and maintain strong bones throughout your entire life. There are two main types of vitamin D: D2 and D3 which add to overall Vitamin D status. The 25-hydroxy vitamin D (25(OH)D) is the major circulating form of vitamin D; thus, the serum 25(OH)D level test is presently considered as the best indicator of how much vitamin D is supplied to the body from cutaneous synthesis and nutritional intake. The test decides whether your vitamin D levels are too high or too low.

Your specialist may ask for a 25-hydroxy vitamin D test for a few distinct reasons. It can enable them to figure out whether excessive or too little vitamin D is causing bone weakness or different variations from the norm. The individuals who are at high risk of having low levels of vitamin D include: people who don't get much exposure to the sun, individuals with obesity, babies who are only breastfed, individuals who have had gastric bypass surgery, individuals who have an illness that influences the digestive tract and makes it troublesome for the body to ingest supplements, for example, Crohn's infection. In addition, your specialist may also want you to complete a 25-hydroxy vitamin D test on the off chance that they've already diagnosed you to have a vitamin D deficiency and need a check on whether treatment is working.

Vitamin D 25-OH test is performed on a sample of blood to gauge the level of Vitamin D (25-OH) in blood. It is performed to affirm Vitamin D (25-OH) inadequacy.
