Results may show:
A positive result indicates an LH surge, suggesting ovulation is likely to occur within the next 24 to 36 hours. A negative result means ovulation has not yet been detected.
Additional notes:
LH levels rise rapidly before ovulation. This test is often used over several days to accurately identify the fertile window.
Before your appointment:
For best accuracy, avoid excessive fluid intake before testing and follow guidance on the timing of the sample.
Why it matters:
Identifying ovulation helps with family planning, fertility tracking, and understanding menstrual cycle patterns.
How often:
As advised, or daily during the expected fertile window.
