The value of ratio of hCG, progesterone in local blood of pregnancy location versus venous blood in the diagnosis of ectopic pregnancy.

概要
OBJECTIVE
The aim of this study is to combine the ratios of venous serum/colporrhagia and hemoperitoneum/venous serum of human chorionic gonadotropin (hCG) and Progesterone (P) to generate and evaluate a new method to improve the prognosis of Ectopic pregnancy (EP).
METHODS
For patients with curettage procedure, curettage material and venous blood were obtained at the same time. For patients receiving culdocentesis and laparoscopic exploration, abdominal fluid and venous blood samples were obtained synchronously during surgery.
RESULTS
The sensitivity and specificity of Rp/v-hCG>1.0 and Rp/v-P>1.0 for diagnosis of EP was 88.2% and 80.71%, 93.8% and 87.53%, respectively. The sensitivity of parallel test (Rp/v-hCG>1.0 or Rp/v-P>1.0) was 92.23%. The specificity of serial test (Rp/v-hCG>1.0 and Rp/v-P>1.0) was 100%. For the area under the ROC curve of Rp/v-hCG and Rp/v-P, the parallel test and serial test were 0.91 and 0.82,0.90 and 0.87, respectively. At the determining threshold point of 1.0, the sensitivity of Rv/c-hCG and Rv/c-P for the diagnosis of EP was 56.73% and 60.01%. The specificity was 100% and 100%, respectively. The sensitivity of parallel test (Rv/c-hCG>1.0 or Rv/c-P>1.0) was 73.33%. For the area under the ROC curve of Rv/c-hCG, Rv/c-P and the parallel test was 0.78,0.80 and 0.87, respectively.
CONCLUSIONS
It is proposed that EP can more rapidly and accurately be diagnosed by multiple biomarkers' test of Rp/v-hCG>1.0 and/or Rp/v-P>1.0, as well as Rv/c-hCG>1.0 and/or Rv/c-P>1.0 via culdocentesis or curettage.
