Lab Tests for Perimenopause
Perimenopause is the transition period before menopause when your ovaries gradually produce less estrogen and progesterone. This phase can last 4-10 years and cause symptoms like irregular periods, hot flashes, mood changes, and sleep disruption. Lab testing helps confirm perimenopause, rule out thyroid disorders that mimic its symptoms, and track hormonal changes over time. With JustLabs, you can order a perimenopause lab panel online at transparent prices — no doctor visit or insurance required.
