About This Test
TSH is secreted by the pituitary gland and controls thyroid hormone production. A single TSH is the best initial test for thyroid disorders. High TSH suggests hypothyroidism; low TSH suggests hyperthyroidism.
📋 Preparation Instructions
No fasting required. Take the test at the same time of day for monitoring purposes, as TSH levels vary slightly throughout the day.
