Diagnosing ectopic pregnancy in the early period provides to reducing mortality and morbidity and gives an opportunity for medical treatment to preserve fallopian tubes. Evaluation of cervical fluid for determining ectopic pregnancy with new promising markers provided different aspects for diagnosing ectopic pregnancy in the present study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this prospective clinical study, ectopic pregnant patients as ectopic pregnancy group (<jats:italic>n<\/jats:italic> = 46), intrauterine pregnant patients as intrauterine pregnancy group (<jats:italic>n<\/jats:italic> = 29) and not\u2010pregnant patients as nonpregnancy group (<jats:italic>n<\/jats:italic> = 10) participated to study. Cervical fluid samples were collected with using merocel sponge. In addition, serum samples were obtained from patients.
