Vitamin D test in Delhi: cost and how to interpret (2026)
Why vitamin D deficiency is so common in Delhi, what the 25-OH test measures, and 2026 prices.
Vitamin D deficiency is one of the most common lab findings in Delhi — pollution, indoor lifestyles and dietary patterns all play a role. Here is what the test measures, what the numbers mean, and what it costs.
The test
The correct test is 25-hydroxy vitamin D (25-OH D). It measures your body's storage form of vitamin D and reflects the last 2–3 weeks. Do not order "1,25-dihydroxy vitamin D" for screening — it is a specialised test and can be normal even when you are severely deficient.
