When taken correctly, ovulation tests are approximately 99% accurate in detecting the LH surge that precedes ovulation. However, these tests cannot confirm whether ovulation actually occurs a day or two later. Some women may have a surge in the LH hormone without releasing an egg.

Will ovulation tests work if you're pregnant? Ovulation tests can (sort of) act as a pregnancy test because LH is molecularly very similar to hCG. If you are pregnant, your hCG levels will be much higher than normal and an OPK may inaccurately detect this and read it as a high LH value.

At 5 DPO, there is no reliably accurate way to check for pregnancy. Most tests check for a hormone called human chorionic gonadotropin (hCG), which the placenta makes. This hormone starts building up in the body after implantation.

Home pregnancy tests are pretty reliable -- in fact, most of them can detect a pregnancy with 97 percent accuracy as early as the day after you miss your menstrual period.

While pregnancy tests can tell the difference between LH and hCG, ovulation tests cannot. Therefore, an ovulation test may show a false positive result from a cross reaction f you have hCG levels that are at or above an LH test's detection sensitivity for LH at the very end of your cycle.

Accuracy and Special Concerns As mentioned above, there is no such thing as a perfectly “accurate” ovulation calendar or calculator. By definition, they are based on averages, and even if you've been charting your periods, your cycle length and ovulation date can change.

These positive results are false-positives—they don't mean you're ovulating. They can signal that your body is trying to ovulate, but they can't confirm that ovulation happened. It's possible for LH to surge and an egg to never release.

Ovulation tests detect LH, which is similar to the chemical that pregnancy tests look for, human Chorionic Gonadotropin (hGC). In fact, they bind to the same receptor. If you're pregnant, you might get a faintly positive ovulation test that's actually detecting hCG, not LH.

No. A home pregnancy test is in no way a valid or reliable route to diagnosing ovarian cancer. The incidences of a positive result being due to ovarian cancer, as opposed to an actual pregnancy, are minimal.
