How accurate are ovulation predictor kits (OPKs)?

Ovulation predictor kits (OPKs) are generally accurate in detecting the luteinising hormone (LH) surge that precedes ovulation. However, the correctness of the results can vary based on the timing of testing, medication use, and individual variations in hormone levels. Using OPKs in conjunction with other tracking methods is recommended for increased accuracy.
