When is the best time of day to take an ovulation predictor test?
Ovulation predictor tests test for a surge in LH (leutenizing hormone). This hormone rises during waking hours, making the best time to take the test *at least 2 hours* after you woke up. The first link below states: late afternoon urine is the best as it contains the highest concentration of LH. The second link below states: The best time to use these tests is between 2 and 8 p.m. First morning pee is not recommended. In any case, the WORST time to take the test is when you first wake up. This is a good time to take a PREGNANCY test, but not an ovulation test.
