Plasma or serum measurement of protein concentration related to preeclampsia during pregnancy (e.g., proteinuria or specific protein markers)
This test helps monitor high blood pressure and protein in urine during pregnancy, which can signal preeclampsia—a serious condition requiring close medical attention.

Why This Test Is Done During Pregnancy
High blood pressure (hypertension) and protein in urine (proteinuria) during pregnancy can indicate preeclampsia, a condition that may lead to serious health risks if left untreated. This test measures protein levels in blood or urine to assess kidney function and blood vessel health in pregnancy.
What to Expect Before the Test
You may be asked to provide a urine sample (often a 24-hour collection) or a blood sample, depending on the specific protein marker being tested. Your healthcare provider will guide you on preparation, such as avoiding certain medications or dietary restrictions.
What the Results Mean
Elevated protein levels in urine or blood may signal early signs of preeclampsia. Your doctor will interpret results alongside other symptoms (e.g., swelling, headaches) and medical history to guide next steps, such as monitoring or treatment adjustments.
Common Causes or Risk Factors
Risk factors for preeclampsia include high blood pressure before pregnancy, chronic kidney disease, obesity, or a family history of the condition. Other contributing factors may include advanced maternal age or multiple pregnancies.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Early detection of preeclampsia through protein testing helps prevent complications like seizures, organ damage, or preterm labor. Regular monitoring ensures timely intervention, such as medication, bed rest, or delivery planning to protect both mother and baby.
