So, probably NOT pregnant?

[Anonymous]

I had a negative HPT 5 days before my missed period, but it was positive one day later. Actually I thought it was negative because I looked at it immediately and it was negative and I threw it in the trash. The next morning I grabbed it out of the trash and it was, in fact, positive -- I just hadn't waited long enough to check. Test again in a few days; you may be in for a surprise!!

FRER are the most sensitive tests on the market, by far.

There was a scientific article published that examined all HPTs and FRER came out ahead of them all. It is called, "Sensitivity of Over-the-Counter Pregnancy Tests: Comparison of Utility and Marketing Messages," by Drs. Laurence A. Cole; Jaime M. Sutton-Riley; Sarah A. Khanlian; Marianna Borkovskaya; Brittany B. Rayburn; William F. Rayburn.

Here's what it says: "Results: First Response Early Result had an analytical sensitivity of 6.3 mIU/mL, which was estimated to detect greater than 95% of pregnancies on the day of missed period."

And: "Clearblue Easy Earliest Results was the second most sensitive test in this study, having an analytical sensitivity of 25 mIU/mL."

And lastly: "The bulk of products we evaluated (five of the seven) had analytical sensitivities of 100 mIU/mL or greater. These products would likely detect 16% of pregnancies or fewer on the first day of the missed period, and evaluators had only 22% to 57% confidence in positive results and 26% to 85% confidence in negative results. Furthermore, three of these five products—AccuClear, CVS One Step, and E.P.T.—had clear indications of technical or design problems in which devices failed to work or were faulty. Three of these five products, including two of the products (Eckerd One Step, CVS One Step, and AccuClear) that failed to work properly, were representative of the numerous similar branded products made by Inverness Medical Innovations Inc. These include the Inverness Medical Early, Rite Aid One Step, Savon Osco One Step, Target Brand, Walgreens One Step, Family Dollar One Step, and several others. The other two lower-sensitivity, lower-confidence products, Fact Plus Select and E.P.T., are made by Ross Products and Pfizer Consumer Healthcare, which also makes other similar products, Fact Plus Pro and Confirm."
