After taking history regarding hypertension and obstetrical examination, patients were subjected to a relevant investigation that is, 5ml of blood sent to an institutional laboratory for the measurement of lactate dehydrogenase enzyme, if it is >400 U/L then it was labeled as raised. Results: The frequency of raised lactate dehydrogenase enzyme (400 U/L) was 13.48% (19/141) women with severe preeclampsia. Conclusion: About 14% of women having Pre-eclampsia had raised lactate dehydrogenase enzyme. Severe preeclampsia is associated with severe multisystemic involvement.
