Suresign Ovulation help identify your most fertile days to increase your chances of conception. Easy to use and over 99% accurate, they detect the surge in luteinising hormone (LH) that precedes ovulation.
Suresign Ovulation Tests are rapid, easy-to-use fertility predictor kits designed to help you identify your most fertile days by detecting the luteinising hormone (LH) surge that triggers ovulation.
During each menstrual cycle, one of your ovaries releases a mature egg – known as ovulation. The egg travels through the fallopian tube and must be fertilised within 24 hours for conception to occur.
Just before ovulation, your body releases a surge in LH levels. The Suresign Ovulation Test detects this rise in LH, signalling that ovulation is likely to occur within the next 24-36 hours – the optimal window to try for pregnancy.
The test uses a lateral flow immunoassay, combining antibodies that specifically detect elevated levels of luteinising hormone in urine.
A positive result indicates that your LH levels have risen sharply – confirming your fertile window and helping you time intercourse for the best chance of conception.
Over 99% accurate in detecting LH surges
Predicts ovulation 24-36 hours in advance
Simple, hygienic midstream urine testing
Clinically tested and CE-marked for reliability
Helps optimise timing for conception naturally
Collect your urine sample – or test midstream by holding the absorbent tip in your urine stream for 5 seconds.
Lay the test flat and wait 5 minutes for the result.
Read the coloured lines:
Two lines (Test & Control visible) – LH surge detected, ovulation likely within 24–36 hours.
One line (Control only) – No LH surge detected; continue testing daily at the same time.
For best results, test at the same time each day and reduce fluid intake for 2 hours beforehand.
Each Suresign Ovulation Test Kit includes:
5 individually foil-wrapped midstream test sticks
1 detailed instruction leaflet
You’ll also need:
Timer or watch
Urine collection container (optional)
Disposable gloves (optional)
If you have a regular 28-day cycle, begin testing on day 11 of your cycle (counting the first day of your period as day 1).
For shorter or longer cycles, adjust accordingly based on your typical cycle length.
Continue testing daily until your LH surge is detected.
| Test Line | Control Line | Result | Meaning |
|---|---|---|---|
| Test line is as dark or darker than control | Visible | Positive | LH surge detected – ovulation likely in next 24-36 hours |
| Test line lighter than control | Visible | Negative | No LH surge yet – continue daily testing |
| No control line visible | – | Invalid | Repeat test with a new stick |
Test between 10 a.m. and 8 p.m. for best LH detection.
Avoid testing with first-morning urine (LH builds up later in the day).
Reduce liquid intake 2 hours before testing.
Ovulation may not occur every cycle – consult your GP if LH surges are consistently absent.
