What Is a Thyroid Test?
The thyroid test measures the functioning of your thyroid gland — a small butterfly-shaped gland in your neck that regulates metabolism, energy, body temperature, heart rate, mood and much more. Medola's thyroid test at home in Nashik includes the complete three-marker panel: T3, T4 and TSH.
TSH
Thyroid Stimulating Hormone — produced by the pituitary gland. The most sensitive thyroid marker. High TSH = underactive thyroid. Low TSH = overactive thyroid.
Most ImportantT4 (Thyroxine)
Main hormone produced by the thyroid gland. Low T4 confirms hypothyroidism. High T4 confirms hyperthyroidism. Measured as both total T4 and free T4 (fT4).
Thyroid OutputT3 (Triiodothyronine)
Active form of thyroid hormone. Low T3 causes fatigue, cold intolerance. High T3 causes palpitations, weight loss and anxiety. Measured as total T3 and free T3.
Active HormoneIndia has over 42 million people with thyroid disorders — and more than 60% are undiagnosed. Thyroid disease is 8x more common in women than men. The thyroid test is one of the most important annual tests every Indian woman over 30 should take.
