Clearblue One Step Pregnancy Test Kit – 2 Tests provides quick, accurate results with over 99% reliability from the day of your expected period. Its easy-to-use design delivers clear results in just two minutes for peace of mind at home.
The Clearblue Early Pregnancy Test provides fast, digital confirmation of pregnancy by detecting the hormone hCG (human chorionic gonadotrophin) in urine.
Its advanced sensor can detect as little as 25 mIU/mL of hCG, allowing testing up to 6 days before your missed period.
Once hCG is detected, the integrated Weeks Indicator estimates how long ago conception occurred – giving an instant picture of your early pregnancy stage.
Over 99 % accurate from the day your period is due
Results in as little as 1 minute
Weeks Indicator 93 % accurate in estimating conception
Simple urine test – no lab needed
During early pregnancy, your body produces the hormone hCG, which doubles every 2-3 days.
The Clearblue test detects this hormone in urine, displaying either:
Pregnant (+ Weeks Indicator)
Not Pregnant
The test measures hCG levels to estimate how many weeks ago conception occurred (1-2, 2-3 or 3 + weeks).
Prepare: Remove the foil wrapper and cap. Use immediately.
Test:
Hold the absorbent tip in your urine stream for 5 seconds, or
Dip the tip into a collected urine sample for 20 seconds.
Wait: A flashing hourglass symbol confirms the test is running.
Read Result:
“Pregnant” / “Not Pregnant” will appear within 3 minutes.
The Weeks Indicator follows automatically.
Results remain visible for approximately 24 hours.
For the most accurate result, test from the day your period is due.
However, you can test up to 6 days earlier with the Clearblue Early Pregnancy Test.
Timing Tips
Testing too early may lead to a false negative if hCG levels are still low.
Use first-morning urine for the highest hormone concentration.
If you test early and get a negative result, repeat after 48 hours.

Clinically validated and widely recommended by healthcare professionals
How soon can I test for pregnancy?
You can test up to 6 days before your missed period, but accuracy improves the closer you are to the expected date.
What if my result line is very faint?
A faint positive line still means pregnant – hCG may just be low. Retest in 48 hours for confirmation.
Can medications affect my result?
Fertility treatments containing hCG may cause false positives. Always check your medication leaflet.
Can I get a false negative?
Yes, if you test too early or drink excess fluids before testing. Retest after a few days if unsure.
How long does the test take?
Results appear within 30 seconds to 3 minutes, depending on hCG levels.
False Positive (rare)
May occur if you:
Recently gave birth or had a miscarriage
Take fertility medicines containing hCG
Have rare medical conditions (e.g. ovarian cysts)
False Negative
Possible if testing too early, using expired tests, or diluting urine with fluids.
If suspected, test again after 48 hours with first-morning urine.
