Ovulation Test

The Clearblue Digital Ovulation Test detects the LH surge that occurs 24�36 hours before ovulation, identifying your two most fertile days with a clear digital smiley face. It is over 99% accurate and displays a flashing symbol while the test is working.

Determine your cycle length and start testing on the recommended day, usually using the first urine after your longest sleep. Insert the test stick into the holder, align the arrows, and wait for the "test ready" symbol. Hold the absorbent tip in your urine stream for 3 seconds or in a collected sample for 15 seconds, and read the result on the screen within 3–5 minutes.
