False positives are problems where the test results are positive, but the patient is not actually positive. False positives can be seen in many clinical tests, such as false positives on pregnancy tests, but the woman is not pregnant, which may be considered to be related to the quality of the test. It may also be due to the presence of luteinizing hormone during ovulation, which is cross-positive with human chorionic gonadotropin. A proportion of false-positive test results may also be related in some way to non-standardized practices, and there may also be human papillomavirus testing, novel coronavirus pathogenetic testing, and HIV testing, so it is often necessary to repeat the test. When false positives are detected in the clinic, it is recommended to consult the relevant department and be sure to repeat the test several times.
