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

An immunoturbidimetric method using a Modular P Analyzer will be used to carry out HSCRP assay, with a quantitation limit of 0.5 mg/L.

All examinations will be carried out by an experience operator with a transvaginal probe on high-resolution ultrasound machines. Pregnancies will be dated from the LMP. Other measurements will be obtained during the scan as the mean gestation sac diameter, volume of the gestation sac and the embryonic heart rate (FHR).
