Consumer Reports rates OPKs about 2 yrs ago.
The top-rated product, the ClearPlan Easy Ovulation Test Pack, was the only one able to detect LH concentrations as low as 22mIU/ml. It was also easier to read than most other models. But even this product will not detect ovulation in the 12 percent of women whose LH peaks at below that concentration.' 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.
'At the other end of the spectrum,' CR says, 'we had to spike the test urine with the highest LH concentration we tested - 91 mIU/ml - before we obtained a positive reading from the First Response Pregnancy Planning Kit. Only 20 - 25% of women have an LH peak that high. Those results cast doubt on the product's label, which claims it contains enough test sticks 'for 90% of ovulating women to detect hormone surge.''
Amazingly, though, that wasn't even the worst-performing test Consumer Reports found. 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. When we tested another six samples at a concentration of 96 mIU/ml, we got only two positive readings,' CR reports.
In the end, the ClearPlan Easy Ovulation Test Pack 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).
