Objective: Normal pregnancy may be complicated by various hematological abnormalities. Thrombocytopenia is the most common platelet disorder in pregnancy. This study is an attempt to assess certain parameters during pregnancy like haemoglobin and packed cell volume, platelet count, mean platelet volume, plateletcrit, prothrombin time and activated partial throboplastin time. Methodology: Various analytical techniques like CELL-DYN-3200 and Blood coagulation analyzer were used in the routine examination of blood samples. Results: It is clearly revealed that both in normotensive and in hypertensive pregnant subjects, there were no significant variation of platelet count and other associated parameters. Even though, physiological anaemia of pregnancy were observed in the case of few study subjects.
