Beta-HCG Levels in Uterine Cavity Lavage for Pregnancies of Unknown Location

The intervention in this study centers on utilizing beta-hCG levels in uterine cavity lavage as a diagnostic tool to differentiate between ectopic pregnancy and early pregnancy loss.The procedure includes females aged 18-45 with positive serum beta-hCG, inconclusive clinical findings, and transvaginal ultrasound results, focusing on beta-hCG levels below 1500-2000 mIU/mL and abnormal progression.The intervention performed before probe curettage (P/C). Before the intervention beta-hCG is measured in venous blood. Patients undergo uterine cavity lavage with 5 ml of saline solution administered and 3 ml of aspirated liquid collected for beta-hCG measurement. Data collection involves beta-hCG levels from lavage fluid and venous blood, pathology results.After the samples were collected, each one was frozen at -80 ºC. All uterine lavage samples were then analyzed later on the same day.
