Luteinizing Hormone (LH) triggers ovulation in women and stimulates testosterone production in men. In women, the LH surge mid-cycle signals the release of an egg. Testing LH levels helps evaluate fertility, irregular periods, and menopause. In men, LH testing can help identify causes of low testosterone. The LH:FSH ratio is also used to evaluate conditions like PCOS.
Luteinizing Hormone — pituitary hormone that triggers ovulation in women and stimulates testosterone production in men. Used in fertility workup, menopause assessment, and hypogonadism evaluation.
Women with irregular cycles, infertility, suspected PCOS or menopause; men with low testosterone, infertility, or hypogonadism workup; anyone evaluating pituitary function.

Your LH (Luteinizing Hormone) results will include values for each of the 1 biomarker tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 1–3 business days.

What can throw off this result
Physician-reviewed “Before your test” pages — what each factor does, for how long, and what to do about it.
An LH (Luteinizing Hormone) test costs $36.99 at TestWell — $42.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $49.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $140.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible. Full cost breakdown →

Both are pituitary hormones acting on the gonads. FSH stimulates egg/sperm development. LH triggers ovulation (women) and testosterone production (men). They're almost always ordered together because the ratio matters: elevated LH:FSH ratio (>2:1) is a classic PCOS sign.
Reproductive-age women, day 3: 1-12 mIU/mL. Mid-cycle surge: up to 100 mIU/mL. Menopausal: 16-66 mIU/mL. Men: 1.7-8.6 mIU/mL. Children before puberty: under 5 mIU/mL.
Day-3 LH:FSH ratio >2:1 is a classic finding in PCOS. Equal or higher FSH than LH in a woman of reproductive age suggests diminished ovarian reserve or perimenopause. In men, both being low suggests pituitary dysfunction; both being high suggests primary testicular failure.
On TestWell, LH is $36.99. Quest Direct lists the same test at $49, walk-in hospital labs typically bill $100-140 without insurance.
The CPT code for Luteinizing Hormone is 83002. FSH (almost always ordered alongside) is 83001.
Ordered directly, an LH (Luteinizing Hormone) test lists at $49.00 at Labcorp OnDemand (prices checked September 2026). TestWell orders the same test at the same Quest or Labcorp patient service centers for $36.99 — $42.99 all-in with the $6 per-order lab processing fee — paid out of pocket at checkout with no insurance, doctor's visit or draw fee; HSA and FSA cards are accepted.
LH (Luteinizing Hormone) test results are typically ready in 1–3 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
No, fasting is not required for an LH (Luteinizing Hormone) test — you can eat normally and book any time of day. Women: note your cycle day when tested.
Cycle day, oral contraceptives and estrogen and antidepressants and antipsychotics can change an LH (Luteinizing Hormone) test result without anything being wrong. Cycle day can shift LH — draw on cycle days 2–5 for baseline. Oral contraceptives and estrogen can lower LH — Cycle-day hormone testing is not meaningful on the pill or with a hormonal IUD/implant. Antidepressants and antipsychotics can lower LH — irregular cycles, low libido or low testosterone on these medications: check prolactin alongside the sex hormones. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
