F2 and preeclampsia: Hematological parameters (hemoglobin, RBC count, and platelets), coagulation markers (prothrombin time, INR, and fibrinogen levels), and renal function tests (serum creatinine and urinary protein levels) were analyzed.<h4>Results</h4>Women with severe preeclampsia showed significantly lower hemoglobin levels (< 35 years: 112.15 g/L, > 35 years: 123 g/L, <i>p</i> < 0.05) and platelet counts.
