What this test is

25-Hydroxy Vitamin D is the form your body stores and the best single indicator of your Vitamin D status. Deficiency is extremely common across urban India even in sunny cities — most adults working indoors test low. Levels under 20 ng/mL are deficient; 20–30 are insufficient; 30–60 are adequate. Symptoms of deficiency include bone pain, muscle weakness, frequent infections, and low mood. Supplementation is cheap and effective once levels are confirmed.

When you need this test

  • Bone or muscle pain
  • Frequent infections or low immunity
  • Persistent fatigue or low mood
  • Indoor-job adults — annual screening
  • Pregnancy
  • Pre-menopausal and post-menopausal women
  • Children with poor growth

How to prepare

  • No fasting needed.
  • If you take Vitamin D supplements, mention your dose and how long you've been on it.
  • Avoid biotin supplements for 48 hours — they can interfere.

FAQs

  • What level should I aim for?
    Most physicians target 40–60 ng/mL — comfortably in the adequate range with a buffer.
  • How long does treatment take?
    An 8-week high-dose course (60,000 IU once a week) usually restores levels, followed by a maintenance dose.
  • How often should I retest?
    3 months after starting supplements, then annually if stable.
  • Is sunlight enough?
    20 minutes of midday sun on arms and face, 3–4 times a week, helps — but most office-going Indians still come up deficient. Supplements are often needed.
  • Why is the test so expensive?
    It uses a specialised technique (chemiluminescence). We've priced it 33% below MRP at ₹1,200.
