Best Pregnancy Test

Research has proven that LH surge is among the best indicators of ovulation, and the kits that Consumer Reports tested are based on LH measurement.
Ten of the 11 kits tested worked like home pregnancy tests, using monoclonal antibody sensing technology. "Since ovulation detection will almost certainly require multiple tests," says CR, "the kits include five or more individual test sticks."
The costlier ClearPlan Easy Fertility Monitor (the electronic tester) was the second most sensitive model tested, detecting LH concentrations as low as 36 mIU/ml, meaning it may work for about 65 percent of women.
Only 20percent to 25percent of women have an LH peak that high. Answer Quick & Simple One-Step Ovulation Test got that dubious honor. "In laboratory tests using urine with an LH concentration of 91 mIU/ml, only one of six tested Answer kits registered positive. In the end, the ClearPlan Easy Ovulation Test Pack ($30.32/5 tests) won, with a borderline "Very Good/Excellent" overall rating (it received an "excellent" for LH sensitivity and was easier to read than most others, but again, it will not detect the LH surge of approximately 12percent of women).
First Response Early Result repeatedly tests as the most sensitive home pregnancy test on the market in scientific studies and consumer reviews. Both scientific studies and consumer testing also find the First Response Early Result to be one of the easiest nondigital pregnancy tests to interpret at low concentrations of hCG. Experts recommend you buy First Response Early Result in two-test kits, as testing again a week later will greatly increase the accuracy of the test. Digital tests like the Clearblue Easy Digital Pregnancy Test (*Est. $18 for three-test kit) are more expensive and less sensitive but do clearly say pregnant or not pregnant.
A major consumer reporting group also offers independent testing to verify the sensitivities and readability of various home pregnancy tests.
