HPT result accuracy

[sweetie246]

Here is some information I got from Babyzone.  Thought those of us with HPT questions could use this information.

"In women who were pregnant, HPTs were positive only 90 percent of the time on the first day of the missed menstrual period. Even a week after a missed period, only 97 percent of the tests were positive. The delay in the detection of hCG is thought to be due to later implantation. Therefore, if you suspect you are pregnant, retest!" 
 

HTH:)

I don't believe this information is completely accurate. I know that the dollar store tests are 25 not 50. This website has all of the sensitivity levels as guaranteed  by the manufacturer:
