Getting the right hormone tests is the first step toward understanding what's happening in your body. But many women receive incomplete testing or aren't sure how to interpret their results. Here's what you need to know.
Essential Hormone Tests
Estradiol (E2): The primary form of estrogen. Levels fluctuate significantly during perimenopause and drop after menopause.
Progesterone: Important to test during the luteal phase (days 19-22 of your cycle) if you're still cycling. Low progesterone can cause many symptoms even when estrogen is normal.
FSH (Follicle Stimulating Hormone): Elevated FSH indicates the ovaries are producing less estrogen. High levels (typically >25-30) suggest perimenopause or menopause.
LH (Luteinizing Hormone): Works with FSH to regulate the menstrual cycle.
Testosterone (Free and Total): Important for libido, energy, and muscle mass. Declines with age and after menopause.
DHEA-S: A precursor hormone that converts to estrogen and testosterone. Declines with age.
Beyond Sex Hormones
A complete evaluation should also include:
- **Thyroid panel:** TSH, Free T4, Free T3, thyroid antibodies
- **Metabolic markers:** Fasting glucose, fasting insulin, HbA1c, lipid panel
- **Inflammatory markers:** High-sensitivity CRP
- **Vitamin D:** Important for bone health, mood, and immune function
- **Iron studies:** Ferritin, iron, TIBC
- **B12 and folate:** Important for energy and brain function
Understanding Your Results
'Normal' isn't always optimal: Lab reference ranges are based on population averages, not what's optimal for you. A 'normal' result can still be associated with symptoms.
Timing matters: Hormone levels fluctuate throughout your cycle (if still cycling) and throughout the day. Consistent timing is important for accurate comparison.
Trends matter more than single results: Looking at how your levels change over time provides more information than any single test.
Working With Your Provider
Bring your symptoms to the conversation, not just your labs. Numbers don't tell the whole story. A knowledgeable provider will consider your symptoms alongside your test results when making treatment decisions.
