Evaluation of vascular endothelial growth factor in early diagnosis of non-typical ectopic pregnancy / 中国综合临床

ABSTRACT

Objective To investigate the best dignostic cut-off point of non-typical ectopic pregnancy(EP) through the determination of vascular endothelial growth factor(VEGF)in 154 cases of suspected ectopic pregnancy patients.Methods The serum level of VEGF in 154 cases with suspected EP was determined by means of immunossay technique,and the results were made into ROC-Curve.Results The acreage behind the curve was 0.95,illustrating that the VEGF can be as a better marker for early diagnosis of EP.The serum VEGF level of 200pg/ml was the cut-off point for early diagnosis of EP throash ROC-Curve.Condusion The serum VEGF can be considered as an early diagnostic marker of EP,which cut-off point is benifical to reducing misdiagnosis of EP.
