Menopause is the permanent cessation of menstruation but is usually not scientifically diagnosed until one full year after a woman’s menstrual periods have stopped. The period leading up to menopause, and the 12 months following, is known as perimenopause. The FSH Rapid Test Dipstick / Cassette (Urine) is a rapid chromatographic immunoassay for the qualitative detection of follicle stimulating hormone (FSH) in urine to aid in the detection of menopause.
