What This Test Measures

The test evaluates a range of biomarkers that reflect physiological changes during pregnancy, such as hormone levels, protein markers, and metabolic indicators. These substances can help track conditions like gestational diabetes, preeclampsia, or other pregnancy-related complications.

Why It’s Done

Your healthcare provider may order this test if you have symptoms like unusual swelling, high blood pressure, or if you’re at higher risk for pregnancy complications. It can also be used as part of routine prenatal care to monitor overall health.

Common Uses in Pregnancy

This test may be used to screen for conditions like high-risk pregnancies, assess fetal development, or evaluate maternal health before or during delivery. It’s not a diagnostic test for a single condition but provides a broad overview of pregnancy-related biomarkers.

Sample Collection and Preparation

Blood is drawn from a vein in your arm. After collection, the sample is processed to separate serum or plasma, which is then analyzed in a laboratory using advanced techniques to measure the biomarkers.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
