Thyroid Test Normal Range — TSH, T3, T4 Values
Understand your Thyroid Test (TSH, T3, T4) report — normal values, what abnormal results mean, and when to get tested.
What is Thyroid Test (TSH, T3, T4)?
Thyroid tests measure how well your thyroid gland is functioning. The thyroid gland produces hormones that control metabolism, energy, heart rate, and body temperature. The most important screening test is TSH (Thyroid Stimulating Hormone). A full thyroid profile includes T3, T4, and TSH. Thyroid disorders are extremely common in India, especially among women — about 1 in 10 Indian adults has a thyroid problem.

What is the normal TSH level?
Normal TSH is 0.4–4.0 mIU/L. TSH above 4.0 suggests hypothyroidism (underactive thyroid). TSH below 0.4 suggests hyperthyroidism (overactive thyroid). During pregnancy, TSH targets are different — your gynaecologist will guide you.
What is the difference between TSH and thyroid profile?
TSH is a single screening test. A thyroid profile (T3, T4, TSH) gives a complete picture. If TSH is abnormal, your doctor will order the full profile. Anti-TPO antibodies may also be added to check for autoimmune thyroid disease.
Should I take thyroid medicine before the test?
No, take your thyroid medication after the blood test, not before. Taking levothyroxine before the test can temporarily increase T4 levels and give inaccurate results.
How often should thyroid be checked?
If on thyroid medication: every 6-8 weeks initially, then every 6-12 months once stable. For screening: once a year for women over 35, those with family history, or anyone with symptoms.
