The listings include three main types: simple test strips, combo packs that pair ovulation and pregnancy tests, and digital ovulation tests with a screen.
All the tests use urine samples. Most report results quickly—typically within about 3 to 5 minutes, depending on the specific test.
A positive result typically shows two visible lines, with the test line equal to or darker than the control/reference line. That pattern indicates an LH surge and likely peak fertility.
Several listings report an LH detection sensitivity of around 25 mIU/ml.
Yes. Some digital tests detect both luteinizing hormone (LH) and estrogen (E3G), so they track more than LH alone.
Both formats appear: some tests are dipped into a urine sample, while others are designed for midstream testing in the urine stream. One listing notes the ideal testing window is in the afternoon—about 10 a.m. to early evening.
Results use a few formats: traditional color indicator lines or +/- style line results on strips, and digital displays that may show symbols (for example a smiling face) to indicate high or peak fertility.
