A TSH blood test is used to evaluate thyroid function by measuring the level of thyroid-stimulating hormone in the blood. It helps diagnose conditions like hypothyroidism and hyperthyroidism, which can affect metabolism, energy levels, and overall health. Doctors often recommend this test when symptoms such as fatigue, weight changes, or irregular heart rate appear. The TSH blood test is simple, quick, and widely available at diagnostic labs. Regular screening can help detect thyroid imbalances early and guide appropriate treatment, ensuring better long-term health and hormonal balance.
