Accuracy of Whole-Blood Testing for Rapid Detection of Pregnancy
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
It is common practice in the emergency medicine department to rapidly assess pregnancy status through the use of either urine or serum in pregnancy tests. Using whole blood instead of urine would facilitate a much more rapid emergency department identification of pregnancy status. No study to date has utilized whole blood for rapid detection of pregnancy status. Set in the busy adult emergency room at Maimonides Medical Center, this study will recruit a sample of women of reproductive age (18-55), who fit the inclusion criteria of being healthy and in need of a pregnancy test for own purpose or diagnostic testing/treatment. Blood samples will be taken from the participants and used in the hCG kits and the remaining blood was sent to the chemistry laboratory to perform the reference gold standard. The reference gold standard for a positive test is an hCG level >25mlU/ml. The research investigators and lab will be blinded to each other's results. Kappa statistics will be done for the measurement agreement between urine pregnancy results and whole blood pregnancy results, and whole blood results with laboratory results.
