Thyroid test in Delhi: TSH, T3, T4 cost explained (2026)
What TSH, T3 and T4 actually measure, when a full thyroid panel is needed, and 2026 prices at Delhi labs.
Thyroid problems — hypothyroidism especially — are common in Delhi, and thyroid testing is one of the most-ordered blood tests in the city. Here is what each parameter measures and what it costs in 2026.
What each test means
- TSH (Thyroid Stimulating Hormone) — the screening test. Rises when the thyroid is underactive.
- Free T4 (fT4) — the active thyroid hormone floating in blood; low in hypothyroidism.
- Free T3 (fT3) — usually normal unless the disease is advanced; rarely needed at screening.
For most people, TSH alone is enough to screen. Add fT4 (and sometimes anti-TPO antibodies) only if TSH is abnormal or your doctor suspects Hashimoto's.

FAQ
How much does a thyroid test cost in Delhi?
A single TSH runs ₹250–₹550. A full thyroid panel (T3, T4, TSH) is ₹450–₹900. Free T3 and Free T4 with TSH is ₹700–₹1,300.
Is fasting required for a thyroid test?
No. TSH, T3 and T4 are not affected by food. If your doctor has combined it with a lipid or sugar test, fast for those.
What time of day is best for a TSH test in Delhi?
Between 8 am and 11 am gives the most reliable reading — TSH is highest in the early morning and drops through the day. Always time repeat tests to the same hour.
Should I stop my thyroid medicine before the test?
No, take it as usual — but note the time of your last dose on the requisition. Some doctors ask you to test before the morning dose so the reading reflects your baseline.
TSH is high — do I need to repeat the test?
If TSH is mildly high (5–10) and Free T4 is normal, most doctors repeat the test after 6–8 weeks before starting treatment. A single high reading is not always disease.
