Fast and accurate results
The Clearblue Ovulation Test is a simple and easy-to-use home ovulation testing kit. In keeping with all Clearblue ovulation testing kits, the Clearblue Ovulation Test incorporates a rapid 'sandwich' assay which detects the pre-ovulatory luteinising hormone (LH) surge present in a woman's urine sample. It is the detection of this LH surge which acts as an accurate and reliable marker of impending ovulation.1-5
- LH levels typically rise 24-36 hours
before ovulation6
- This LH 'surge' is an accurate and
reliable marker of impending ovulation.1-5
Example of typical test result seen during LH surge.

- Accurate - over 99% accurate in detecting the LH surge in urine7
- Reliable - 7 sticks to increase the chances of detecting the LH surge in a cycle
- Fast - gives a result in 3 minutes
- Trustworthy - from Clearblue, the World's Leading Brand in home pregnancy and fertility testing
