LH levels: what's normal, high and low
A pituitary hormone that triggers ovulation in women and testosterone production in men. Cycle-dependent in women.
Medically reviewed by Youmna DiStefano, MD · Last reviewed September 2026
The short answer
LH is measured with a standard blood draw; no fasting is needed. A typical reference range is 1.70 – 8.60 mIU/mL (male, age 18+; more bands below). At TestWell it's $36.99 all-in as LH (Luteinizing Hormone), results in 1–3 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

LH Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| Male, age 18+ | 1.70 – 8.60 mIU/mL |
| Female, age 18+, varies by cycle phase | 1.90 – 12.5 mIU/mL |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
What your LH result may mean
In women, often reflects menopause or PCOS. In men, can reflect testicular issues.
