Material and Methods: The study was retrospective and comprised 198 patients with preeclampsia, 158 with severe preeclampsia and 40 with non -severe preeclampsia, as well as 126 pregnant women who had a healthy pregnancy as the control group. From the hemogram parameters, platelet count (PLT), neutrophil count, mean platelet volume (MPV), mean erythrocyte volume (MCV), leukocyte count and neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (TLR) and platelet/neutrophil ratio (TNR) were calculated. The pregnant women included in the study were compared in terms of these parameters. Results: While there was no statistically significant difference between the groups in the statistical analysis of MCV, MPV, NLR, and TNO, which are the parameters studied in PE groups with and without severe features, a statistically significant difference was found in these parameters between the control group and the preeclampsia group. At the TNO 35,1250 cut-off value, the sensitivity was 83.8 %, the specificity was 41.3 %, the positive predictive value was 69.17 %, and the negative predictive value was 61.90 %, and it was found that this value predicted the presence of PE as 69%. Discussion: In this study, we discovered that MPV, MCV, TNO, and NLO levels differed significantly between the PE and control groups. However, the sensitivity and specificity rates of these parametria in the detection of preeclampsia are far below significant values.eninfo:eu-repo/semantics/openAccessHemogramMCVMPVNLRPLRPNRPreeclampsiaArticle155369372WOS:00122291000000710.4328/ACAM.22173N/A
