Ovulation prediction kit

Ovulation prediction kit (OPK) measures the Luteinizing Hormone (LH) in your urine. Small amount of LH is present in the urine every day and its level gradually increases as ovulation approaches. The LH surges within 24 hours before ovulation and OPK is positive the day before you ovulate.


But some conditions could give you false positive result. These include

Polycystic ovarian syndrome(PCOS) where there is a raised blood level of the LH

Premature menopause where the ovary ages prematurely  in women below the age of 35

Perimenopause or menopausal transition where the level of LH is high
