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.
Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.
