Evaluation of Serum Levels of C Reactive Protein (CRP) and Its Correlation With Fetal Ultrasound Parameters in the Prediction of Threatened Miscarriage in the First Trimester

This observational study will enroll 100 pregnant women, with 50 in the threatened miscarriage group and 50 healthy controls, to compare serum C reactive protein (CRP) levels and fetal ultrasound findings for predicting early pregnancy loss. Women presenting with first trimester bleeding and cramps concerning for threatened miscarriage will undergo blood testing to measure C reactive protein (CRP) levels and fetal ultrasound to assess parameters including crown-rump length, heartbeat, yolk sac size, and embryonic motion. The control group will consist of 50 low-risk pregnant women without threatened miscarriage matched for gestational age. Controls will undergo the same blood and ultrasound assessments. Researchers will compare serum C reactive protein (CRP) levels and ultrasound measurements between the threatened miscarriage and control groups. They will analyze which parameters differ significantly between groups and examine the predictive utility of C reactive protein (CRP) levels versus ultrasound for determining pregnancy viability. Key outcomes will include correlation of C reactive protein (CRP) with ultrasound parameters, and diagnostic accuracy of C reactive protein (CRP) levels versus ultrasound in predicting pregnancy loss in threatened first trimester miscarriages. This study aims to help optimize early pregnancy loss prediction and counseling for women with potential threatened miscarriage.
