Evaluation of the Performance of a Rapid Pregnancy Diagnostic Test.

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to evaluate the effectiveness of a rapid pregnancy diagnostic test to improve the medical care of patients in emergency room.

Detailed Description
-----------------
The most current gynecological consultations in emergency unit first lead to a pregnancy diagnostic test. The gold standard used is the diagnostic test based on determination of the β-human chorionic gonadotropin concentration. But this assay need time and expect women to wait for hours. A 5-minutes pregnancy diagnostic test has been developed in France. A 62-patients study showed that results obtained with the rapid test were correlated with results obtained with the test based on determination of the β-human chorionic gonadotropin concentration. The purpose of this study is to evaluate the efficiency of the 5-minutes pregnancy diagnostic test realized in emergency room, in comparison with the blood determination of the β-human chorionic gonadotropin concentration which is only tested in medical laboratory. A little amount of total blood sample used for gold standard test will be used to assess sensibility, specificity, positive or negative predictive values of the rapid pregnancy diagnostic test.
