Placental growth factor (PLGF) concentration in serum/plasma

What Is Placental Growth Factor (PLGF)?

Placental growth factor (PLGF) is a protein produced by the placenta that plays a key role in regulating blood vessel formation. It helps support the development of the placenta and fetal blood supply. In pregnancy, PLGF is often monitored to detect early signs of complications like preeclampsia or poor placental growth.

Why Might You Need This Test?

Your healthcare provider may order a PLGF test if you’re pregnant and experiencing symptoms such as high blood pressure, protein in urine, or other signs of pregnancy-related conditions. It may also be used in early pregnancy screening or to evaluate placental function in certain cases.

How Is the Test Performed?

A blood sample is drawn from a vein, usually in your arm. The blood is then processed to separate the serum or plasma, where PLGF levels are measured using a specialized immunoassay technique. The test typically takes a few hours to complete, and results are compared to reference ranges for the condition being assessed.

What Do the Results Mean?

Results are interpreted based on clinical context, such as your pregnancy timeline or symptoms. Abnormal levels may signal potential risks, but they are not standalone diagnoses. Your doctor will discuss findings with you and may recommend further testing or monitoring.
