Preeclampsia is difficult to diagnose. In the US, there are no diagnostic tests for preeclampsia approved by the FDA.⁸⁻⁹
The symptoms used to diagnose preeclampsia can be caused by other conditions. Doctors consider other symptoms to reach a diagnosis such as a low platelet count, poor liver or kidney function, fluid in the lungs and visual disturbances or severe headache.¹⁰
Delivery of the baby is the only cure for preeclampsia.
Doctors face a dilemma when a patient has symptoms. An early delivery impacts the health of the baby. Delaying delivery may be very risky for the mother and possibly the child. The doctor’s decision is even harder if they are unsure of the diagnosis.
A diagnostic test could help doctors rule out preeclampsia in many patients, and determine which patients need more care or an early delivery.
