First Response Early Result

Reviews say that First Response Early Result is the most sensitive home pregnancy test and it delivers the earliest possible results. In tests, First Response consistently detects 12.5 mIU of, hCG, an early pregnancy hormone. In product testing, First Response Early Result detected pregnancy on the first day of a missed period 95% of the time. Experts recommend that you buy First Response Early Result in two-strip kits, since most women will want to test twice, waiting a week between tests. All home pregnancy tests, including this one, receive user complaints about false positives and false negatives, and some women find the colored lines hard to interpret. Digital tests like Clearblue Easy Digital Pregnancy Test (*est. $19 for two-test kit) are more expensive and less sensitive but do clearly say "pregnant" or "not pregnant."
