Clearblue Ultra Early Pregnancy Test 2 PacknClearblue Digital Ultra Early Pregnancy Test kit combines ultra-sensitive early detection of the HCG pregnancy hormone with unmistakably clear results in words. Our most sensitive digital home pregnancy test can be used up to 6 days before your missed period. (1) 78% of pregnant results can be detected 6 days before your missed period (which is 5 days before you expect your period). Test sensitivity is 10mIU/ml. Testing is made easy by an extra wide tip and our unique stop light feature, which flashes to tell you when you have sampled enough urine. Plus our Floodguard(TM) Technology makes it easy to test correctly. Once the test is running, the Smart Countdown(TM) will appear on screen to reassure you the test is progressing, counting down to your clear digital result in words, which will appear on screen within 1-5 minutes. Like all Clearblue Pregnancy Tests, Digital Ultra Early is over 99% accurate from the day you expect your period
