25 - Hydroxy Vitamin D
Vitamin D helps our body absorb calcium and phosphorus, and maintain strong bones and teeth. Vitamin D (25-OH) test measures the level of Vitamin D (25-OH) in the blood which is a useful indicator of many bone related problems.
The prevalence of Vitamin D deficiency is quite common across all age groups. If your Vitamin D levels are low you may experience bone pain, muscle weakness, fatigue, and mood changes.
This test helps in diagnosis of osteoporosis (bone weakness), rickets (bone malformation), and osteomalacia (bone softening).
Eating foods containing Vitamin D in addition to taking supplements and proper exposure to sun can help keep your Vitamin D levels within the normal range.
