Measuring TSH in a blood test is considered the best first-line screening test for most thyroid problems due to its sensitivity:
Early Warning System: Because of the log-linear relationship in the feedback loop, a very small change in the active thyroid hormones (T4/T3) causes a very large, reciprocal change in TSH. This means TSH levels become abnormal earlier than T4 or T3 levels, often acting as an early warning signal of impending thyroid dysfunction.
Diagnosing Disorders:
High TSH: Strongly suggests the thyroid gland is underactive (Hypothyroidism) and the pituitary is overcompensating.
Low TSH: Strongly suggests the thyroid gland is overactive (Hyperthyroidism) and the pituitary is attempting to shut it down.
Monitoring Treatment: The TSH test is essential for checking whether patients receiving medication for hypothyroidism (like levothyroxine) are on the correct dose. The goal of treatment is often to keep the TSH level within the normal or a specific target range
