What is this test?

Preeclampsia, historically called toxemia of pregnancy, is a condition that can develop during pregnancy. A preeclampsia panel combines laboratory tests that evaluate the kidneys, liver, and blood platelets, which may be affected when blood pressure becomes dangerously high.

Why might I need this test?

Clinicians may order this panel when a pregnant patient has high blood pressure, swelling, headaches, visual changes, upper abdominal pain, or new-onset protein in the urine. The results help assess the severity of possible organ involvement and guide pregnancy management.

How is the test performed?

Blood and urine samples may be collected and tested for markers of kidney stress, liver injury, and platelet function. The exact tests included can vary by laboratory and are interpreted together with blood pressure readings, symptoms, and the other findings of pregnancy.

How do I prepare for the test?

Follow the instructions provided by your healthcare professional. A urine collection container or timed urine collection may be needed, and fasting is generally not required unless the laboratory specifically says otherwise.

Frequently asked questions

Is toxemia of pregnancy the same as preeclampsia?
Yes. Preeclampsia is the current clinical term; toxemia of pregnancy is an older name that can also refer to pregnancy-related high blood pressure disorders.
Does this panel diagnose preeclampsia?
No single laboratory result usually diagnoses preeclampsia by itself. The panel supports diagnosis and severity assessment when combined with blood pressure readings, symptoms, and other clinical findings.
Why are several laboratory tests included?
Preeclampsia can affect multiple organs. Testing kidney function, liver enzymes, platelets, and urine protein helps clinicians look for complications and monitor the mother's condition.
