VITAMIN D 25 - HYDROXY
No special preparation required
Vitamin D is a nutrient required by the body to maintain healthy bones. It also supports the health of our immune system, muscle & brain. Vitamin D is not natrually found in foods unless fortified like fortified milk, cereal & salmon. Your body can only absorb calcium when vitamin D is present. Your body makes vitamin D when direct sunlight converts a chemical in your skin into active form of the vitamin. Risk factors for vitamin D deficiency are old age, lack of sun exposure, dark skin, malabsorption & obesity. Vitamin D deficiency increases the risk of osteoporosis, rickets, diabetes, heart disease & can lead to depression. This is the most widely used test that helps to diagnose whether you are deficient in vitamin D & require supplements.
A vitamin D test measures the amount of vitamin D in the blood and aids in assessing bone and parathyroid function. Elevated levels may indicate excessive supplementation or other underlying medical conditions, whereas decreased levels may indicate bone metabolism issues including osteoporosis or hyperparathyroidism. Monitoring vitamin D levels helps to keep overall health and bone health at optimal levels.
Adequate levels of Vitamin D are necessary for healthy teeth and bones.
There are two forms of vitamin D: vitamin D2 (found in cereals and dairy products) and vitamin D3 (found in sunlight, eggs, and fatty fish).
In order to assess if a person has a vitamin D deficit, a blood test measures the conversion of both forms into 25(OH)D.
Dr. LalPathlabs diagnostic facilities around the nation, including Bengaluru, offer accurate 25-hydroxy vitamin D testing with online cost-checking prior to appointment.
Physicians recommend the 25-hydroxy vitamin D test to assess vitamin D levels in patients exhibiting symptoms of deficiency, including abnormalities, fractures, and soft, brittle bone in youngsters. Additionally, in those who are particularly vulnerable to Vitamin D deficiency—such as those with osteoporosis, obesity, a history of gastric bypass surgery, restricted sun exposure, or illnesses like Crohn's disease that affect vitamin absorption—this blood test may be utilized for diagnosis and monitoring.

25-Hydroxy vitamin D represents the main body reservoir and transport form. Mild to moderate deficiency is associated with Osteoporosis / Secondary Hyperparathyroidism while severe deficiency causes Rickets in children and Osteomalacia in adults. Prevalence of Vitamin D deficiency is approximately >50% specially in the elderly. This assay is useful for diagnosis of vitamin D deficiency and Hypervitaminosis D. It is also used for differential diagnosis of causes of Rickets & Osteomalacia and for monitoring Vitamin D replacement therapy.
