Significance of Serum TSH
Serum TSH refers to the level of thyroid-stimulating hormone in the blood serum, which is essential for evaluating thyroid gland function and diagnosing conditions such as hypothyroidism.

Additionally, Serum TSH levels can indicate hormonal interactions in women experiencing infertility. Elevated levels of TSH, above 4.5 μIU/ml, signify hypothyroidism, underscoring its importance in medical assessments.
