Luteinizing hormone in urine. Most home urine tests to predict ovulation determine only
the presence of LH (called qualitative testing) and not the specific level or
quantity. Home urine test results are either "positive" (LH is present) or
"negative" (LH is not present).
Many conditions can change LH levels. Your doctor will
discuss any significant abnormal results with you in relation to your symptoms
and past health.

What Affects the Test
Results of the luteinizing
hormone test may be affected by:
- The use of certain hormones, including those
containing estrogen or progesterone (such as birth control pills).
- The use of medicines, such as clomiphene, spironolactone,
naloxone, phenothiazine, and those given for seizures
- Diagnostic imaging procedures, such as a thyroid scan or
bone scan, that use a radioactive substance (tracer) and were performed within
7 days prior to LH testing.
What To Think About
- If you are taking a medicine that contains
testosterone, estrogen, or progesterone (such as birth control pills), ask your
doctor whether you should stop taking it for several days before having a
luteinizing hormone (LH) test.
- You can buy home ovulation kits at
a drugstore to help identify the most fertile days of a woman's menstrual
cycle. The kits test for LH in urine with a dipstick or test strip. Other home
ovulation tests that measure the amount of LH in urine and display the results
on a small computerized monitor also are available.
- Other tests for
ovulation include measuring basal body temperature, testing the progesterone
level after ovulation in the menstrual cycle, and noting changes in cervical
mucus. For more information, see the topic
