For Best Results: First morning urine usually contains the highest concentration of HCG and is therefore the best speciem when performing the urine test. Easy to Read: Two lines means pregnant and one line means not pregnant. The test line might be slight lighter than the control line. If the test line is weak, it is recommended to test another time days later. Test Early: Predict your pregnancy before your missed period. Test results are over 99% accurate. Fast and Sensitive: HCG level as low as 25 mIU/ml can be detected. Place the absorbent tip in the urine stream for 10 seconds, lay the strip flat and wait 3 minutes and check the results.
