How to Diagnose Pre-eclampsia
The doctor will ask about your symptoms and medical history, and perform a physical exam.
Tests may include:
Blood Pressure Measurement
A blood pressure reading of 140/90 or higher is considered high whether or not a woman is pregnant. During pregnancy, blood pressure in the third trimester is compared with blood pressure before pregnancy or during the beginning of the second trimester. Blood pressure is elevated during pregnancy if:
- The first number in your blood pressure reading has risen 30 mmHg or more, or
- The second number has risen 15 mmHg or more
Fluid Retention Assessment
Sometimes fluid retention is obvious during the physical exam. Fluid retention may cause weight gain of more than five pounds in one week. Sudden weight gain over one or two days is almost certainly due to fluid retention.
Urine Test
Under normal circumstances there is no or minimal measurable protein in urine. In pre-eclampsia, significant amounts of protein usually appears in the urine.
Blood Tests
Blood test include checking:
- Complete blood count
- Clotting factors
- Electrolytes
- Kidney and liver function
