Thyroid function is the general term of T3, T4, FT3, and FT4, which is closely related to thyroid function and is an important basis for the diagnosis of hyperthyroidism and hypothyroidism. Detection of thyroid hormone has been widely used in the diagnosis of hyperthyroidism and hypothyroidism and has become an important means to judge efficacy and monitor recurrence. The LH content in urine can accurately measure the ovulation period of a woman. After pregnancy, the HCG value in a woman will rise sharply in a short period and remain until the level of non-pregnancy is restored after delivery. Detection of HCG concentration is a reliable indicator for determining pregnancy.
