First Response Early Result Pregnancy Test

1. Journal of the American Pharmacists AssociationDetails/Subscribe

This clinical study takes previous testing of home pregnancy tests (HPTs) a step further by using urine samples with a mixture of human chorionic gonadotropin (hCG) designed to mimic that seen in the early weeks of pregnancy. First Response Early Result is the most sensitive, detecting 6.3 mIU/ml of the hCG mixture. Test readers also have the highest confidence in reading positive and negative test results of the First Response Early Result.

This clinical study first evaluates the concentration of human chorionic gonadotropin (hCG) in the urine of 25 women achieving pregnancy at the time of their missed periods. The researchers then test 18 home pregnancy tests for sensitivity at various concentrations of hCG. First Response was consistently the most sensitive, able to detect 12.5 mIU/ml of hCG, and it would have caught 95 percent of pregnancies in this study on the first day of a woman's missed period.

3. Clinical Chemistry

This clinical study evaluates 592 urine samples from women at various stages in their pregnancies to determine what form of human chorionic gonadotropin (hCG) is prevalent at what time. Researchers also evaluate the sensitivity of 15 home pregnancy tests (HPTs) at various concentrations of both regular hCG and another form, hyperglycosylated hCG (H-hCG). They find that the hyperglycosylated form of hCG makes up more than half of the hCG in the urine of pregnant women in the first weeks of pregnancy. First Response is able to detect both forms of hCG at concentrations of 25 mIU/ml.
