Pregnancy as we know is the state of carrying a developing embryo or fetus within the female body. This condition can be indicated by positive results on an over-the-counter urine test, and confirmed through a blood test, ultrasound, detection of fetal heartbeat, or an X-ray. Pregnancy lasts for about nine months, measured from the 1st day of the woman's last menstrual period (LMP). It is conventionally divided into three trimesters, each roughly three months long. Normal pregnancy implies final positive outcome for both pregnant mother and her newborn child. Any deviation from this final result is categorized as abnormal pregnancy/Complicated pregnancy. Preeclamptic pregnancy is one of such type of complicated pregnancy with threat to both fetus and pregnant women. There are so many reasons for preeclampsia/eclampsia syndrome related to various factors associated with pregnancy. In this prospective study we study the effect/consequences of abnormal platelet profile on pregnant and their fetus along with proper control subjects. For this study we randomly selected total 100 pregnant ladies admitted in OBG department of JNKTMCH out of which 50 were preeclamptic, considering all compounding factors into account. Emphasis is mainly to ascertain that whether platelet profile derangement is a cause or effect of preeclampsia syndrome. In this study we emphasize on clinic-pathological aspects of the effect of platelet profile derangement and development of preeclampsia, as well as its implication in future clinical management of such patients on the basis of observations of our study, if any.
