AbstractAimThe present study aims to evaluate how components of complete blood count are altered in women with a history of recurrent pregnancy loss.Material and MethodsThis was a retrospective evaluation of 60 women who had a history of recurrent pregnancy loss, 60 healthy women who had a first trimester pregnancy and 60 healthy parous women.ResultsWhen compared with pregnant women and healthy controls, the women with a history of recurrent pregnancy loss had significantly higher red cell distribution width (RDW) and platelet distribution width (PDW) (P = 0.001 for both). Thrombophilia was detected in 31.7% of the women who had a history of recurrent pregnancy loss (19 out of 60). When compared to the women without thrombophilia, the women with thrombophilia had significantly lower body mass index (P = 0.034) but significantly higher RDW, PDW and plateletcrit (respectively, P = 0.043, P = 0.001 and P = 0.002). There were significant and positive correlations between RDW and PDW (r = 0.615, P = 0.001), RDW and plateletcrit (r = 0.343, P = 0.007) and PDW and plateletcrit (r = 0.340, P = 0.008) in women with a history of recurrent pregnancy loss.ConclusionAn elevation in PDW and RDW values was found to be associated with recurrent pregnancy loss.
