Ovulation predictor kit
Abbreviation: OPK
An ovulation predictor kit (OPK) is a home urine test that detects the LH surge that occurs before ovulation, helping you identify your most fertile days. Most kits include multiple test strips to use daily, starting a few days before you expect to ovulate. A positive result, usually shown as a test line as dark as or darker than the control line, suggests ovulation is likely within 12 to 36 hours. Some advanced digital OPKs also track oestrogen levels to give a wider picture of your fertile window. OPKs are widely available at pharmacies across Singapore without a prescription.

A positive OPK confirms an LH surge has occurred but does not guarantee that ovulation followed, as the egg can sometimes fail to release. If you get consistently positive results across many days of the cycle, speak to your doctor as this may indicate a hormonal imbalance.
