Follicle Stimulating Hormone (FSH)

Methodology

The FSH assay utilizes a sequential two-step immunoenzymatic (“sandwich”) assay to determine hormone levels from human serum.

Test Utility

This test measures the amount of follicle stimulating hormone in the bloodstream. It can aid in determining reproductive issues in men (low sperm counts) and women (development of eggs), determine menopause status, investigation of menstrual irregularities, and diagnose pituitary or hypothalamus disorders.

  • Room temperature: 15°C to 30°C for no longer than 8 hours

  • Refrigerated: 2°C to 8°C for up to 48 hours

  • Frozen: -20°C or lower, samples should be thawed only once.
