Platelet indices during normal pregnancy and pre-eclampsia.
Platelet count and mean platelet volume (MPV) were estimated in 349 normal pregnancies at various gestational stages, and in 30 cases of pre-eclampsia. A probability plot was constructed from these data using discriminant analysis of MPV versus platelet count for the pre-eclamptic versus normal pregnancies. The sensitivity for pre-eclampsia was 90% (27/30) and the specificity was 83.3%. This plot may be of use in confirming risk of pre-eclampsia.
