The key thing is early diagnosis so that it can be managed with a physician. A blood test can diagnose the severity of it by measuring uric acid level, platelets level in your blood, clotting level and liver function. If a patient's preeclampsia becomes very severe, she might develop HELLP (Hemolysis, Elevated Liver enzyme levels, and Low Platelet levels) syndrome. Once any of these symptoms appear, immediate treatment is required and in severe cases, patients may be admitted and given magnesium sulphate to stablise the condition and administer medication (steriods) to speed up the delivery of the baby's lungs to bring forward delivery. Treatment for preeclampsia is to deliver the baby as soon as possible, depending on the condition of the mother and baby. We also look out for very bad edema (swelling) of the body, which indicates greater severity of the preeclampsia condition.
