Thyroid tests measure how well the thyroid gland is working. The most common test is TSH (Thyroid Stimulating Hormone), which screens for hypothyroidism and hyperthyroidism. A full thyroid profile includes T3, T4, and TSH.
Thyroid disorders are extremely common in India, especially among women. Regular thyroid testing is recommended for those with symptoms like unexplained weight changes, fatigue, hair loss, or menstrual irregularities.
