Home urine LH testing
A large amount of luteinizing hormone (LH), also referred to as the
“LH surge,” occurs prior to ovulation. This is the most
useful of all laboratory tests available for ovulation prediction. This
surge may be detected in blood testing in our office or urine testing
at home. Although a number of home ovulation prediction kits are commercially
available, we recommend Clear Plan Easy. This particular kit is simple,
accurate, and takes less than five minutes to perform the test. Testing
should begin prior to the expected time of ovulation, generally beginning
on day 10 of the menstrual cycle. It is important to test your urine
between 11:00 am and 2:00 pm to detect the onset of the LH surge. Although
this may seem inconvenient, it is the most accurate in detecting the
beginning of the LH surge. Remember, too, that testing takes less than
5 minutes. When the color of your test is the same as or darker than
the reference test, you are having an LH surge. Ovulation will occur
the following day. Therefore, unless other tests or procedures are scheduled,
you should have intercourse that day and the following day. You may
stop testing after you test positive for your LH surge.
