What we often check instead
Depending on history: CBC/ferritin with heavy bleeding, TSH, lipids, glucose/A1c, and pregnancy test when indicated. Endometrial assessment may be required before hormones if bleeding is abnormal.

Do I need blood tests before starting HRT?
Medically reviewed by Dr. Nathan Roth, MDCM, FRCSC, FACOG · Updated 2026-11-01
Do I need menopause blood tests before starting HRT?
Not always. In women over 45 with typical menopause symptoms, diagnosis is often clinical and FSH testing is optional. Hormone levels fluctuate in perimenopause and a single estradiol/FSH pair rarely decides treatment. Testing is more useful for atypical presentations, premature menopause concerns, or to exclude other conditions (thyroid, anemia, pregnancy when relevant). HormoneFit orders labs when they change decisions — not by default for every patient.
- Classic symptoms after 45 often need no diagnostic FSH
- Perimenopause labs can mislead if over-interpreted
- Baseline lipids/glucose may still matter for midlife health
- Unexplained bleeding needs evaluation before HRT
