The Biotime FSH Rapid Quantitative Test is designed for the detection of Follicle Stimulating Hormone (FSH) concentration in human serum. FSH is a glycoprotein hormone secreted by the anterior pituitary gland, consisting of α and β peptide chains linked by covalent bonds. In females, FSH promotes follicular growth, maturation, and estrogen secretion by activating aromatase in granulosa cells. In males, FSH supports the formation and maturation of seminiferous tubules and spermatogenesis.

FSH levels fluctuate during the menstrual cycle, with peaks coinciding with LH surges around ovulation. Measuring FSH assists in evaluating reproductive health, diagnosing endocrine disorders, and assessing fertility potential. The Biotime FSH test provides fast, quantitative results and can be used in conjunction with LH testing to evaluate ovarian and pituitary function.
