Home pregnancy tests claim to be 99% accurate, but are they? Women who rely on home pregnancy tests to tell them they're expecting may not be getting the most reliable information.
A new medical study says home test kits do not detect a pregnancy shortly after a missed period, even though many of them claim to do just that. In fact only one detected pregnancy with 95 percent accuracy.
Wendy Griffin of Tyler is a mother of two who wants to be a mother of three.
"We've been trying [to have a baby] for about six months," she says.
This weekend she had a glimpse of hope she may be pregnant after taking a home test.
"It just almost seemed unbelievable to me. I thought maybe this is the one time I am getting a false positive, so I came in to see Dr. Spencer for another test," she explains.
After a blood test, Wendy found out she is definitely going to be a new mom. Her at-home pregnancy test was correct, but Dr. Charla Spencer at Mother Frances says home tests aren't always so accurate.
"At least 20-30% of the time, our results differ from what their’s are," Dr. Spencer said.
A new study found the 99%-accurate claims right after a missed period just aren't true. In fact, only one test in the study, the First Response, Early result was found to detect pregnancy with 95% accuracy. Clear Blue Easy came in second, and all the rest of the 18 tested were only about 16% accurate. Dr. Spencer says that it is important for women to know, and offers this advice if you use the tests.
"A lot of the packages say they are accurate after one to two days after a missed cycle, but I usually say wait a week."
The study did show, a week or more after a missed period, the tests were all accurate.
