The Apollo Pharmacy LH Ovulation 5 Day Test Kit helps you find your most fertile days by detecting the LH surge in urine. Collect a urine sample, apply it to the test strip or device as directed in the leaflet, wait a few minutes, and then read the result. A positive result means your LH has surged, and ovulation is likely within the next 24–36 hours. For best accuracy, follow the instructions in the kit carefully.
