Platelet Indices and Recurrent Pregnancy Loss

One sample of 20 mL venous blood was drawn by standard phlebotomy from all of the participants. This sample was kept for the evaluation of hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), erythrocyte count, leukocyte count, platelet count, platelet distribution width (PDW), MPV and plateletcrit by means of an automated commercial counter (Coulter counter, Max Instruments Laboratory). After this venous blood sample was conveyed into a sodium citrate tube, it was transported in a temperature-controlled container and collected in plastic provettes (Falcon blue cap) containing 3 mL of 3.8% sodium citrate dihydrate and 136 mM glucosium. Then the samples were sent to the laboratory.
