Understanding the Dual-Hormone Advantage
What makes the Clearblue Advanced test unique is its ability to track two key fertility hormones instead of just one:
- Estrogen: Rises in the days leading up to ovulation, signaling the opening of your high-fertility window.
- Luteinizing Hormone (LH): Surges sharply 24 to 48 hours before ovulation, pinpointing your peak fertility days.
By monitoring both estrogen and LH, the test identifies your “High Fertility” days in addition to your “Peak Fertility” days. This gives you and your partner extra advance notice to plan intercourse, significantly increasing your overall chances of conception each cycle.

Clear Digital Results (No More Guessing Lines)
One of the most common frustrations with standard line-based ovulation strips is the ambiguity of interpreting faint lines or wondering if the test line is as dark as the control line. Clearblue eliminates this guesswork entirely with a smart digital display screen.
- Blank Circle (Low Fertility): Indicates hormone levels are at baseline.
- Flashing Smiley Face (High Fertility): Alerts you that your estrogen is rising and your fertile window has begun.
- Constant Smiley Face (Peak Fertility): Confirms your LH surge has been detected, marking your absolute peak days for conception.
Practicality and Ease of Use
The kit includes a digital holder and multiple absorbent test sticks. Testing is straightforward: remove the cap, place the absorbent tip directly in your urine stream for 3 seconds (or in a collected sample), and replace the cap. Lay the stick flat, and within minutes, the smart algorithm reads the hormone levels and displays the corresponding smiley face on the screen.
