If tested regularly and monitored over time, an LH test can help with ovulation tracking.  If you are trying to conceive, becoming familiar with your ovulation patterns can be useful information for identifying your fertile window.

During a typical menstrual cycle, LH levels are highest just before ovulation. This surge triggers the release of an egg from the ovary, then levels decrease after ovulation and remain low during the luteal phase.⁴ Hormone levels may fluctuate widely throughout the menstrual cycle. Understanding these fluctuations can be helpful for tracking ovulation patterns.

If you have irregular cycles, your LH surge may be less predictable, making it more difficult to track ovulation.

However, if you have irregular cycles, your LH surge may be less predictable and difficult to identify.

An at-home urine test can detect the LH surge that normally occurs around the middle of the menstrual cycle just before ovulation. It is typically used to help predict the most fertile window for women hoping to become pregnant because the increase in LH triggers the release of an egg. If the at-home urine LH test result is positive, it suggests that ovulation will occur in the next 24 to 48 hours.

The Labcorp OnDemand Luteinizing Hormone (LH) Test measures the levels of LH in your blood to assess your hormone status. LH is often evaluated in the context of other hormones such as follicle-stimulating hormone (FSH). An LH blood test provides a snapshot of your hormone level at the time of testing; you will receive test results a few days after the sample is collected.

Your testing will be performed in a CLIA-certified clinical laboratory. Labcorp provides leading-edge medical laboratory tests and services through a national network of primary clinical laboratories and specialty testing laboratories. Our labs perform regular quality assurance testing to ensure our results are accurate.

Your results will be provided to you through our secure online portal to view or print. Results are also provided to PWNHealth, which provides professional healthcare provider services for OnDemand tests. If you are accessing your results through your Labcorp Patient account, all users linked to the account will have access to all OnDemand test results. Results may also be provided to a local, state, or federal health authority, but only when legally required. For example, many states require the testing laboratory and healthcare provider to report test results for certain communicable diseases, such as sexually transmitted diseases or COVID-19, to local or state health departments.
