Why Might This Test Be Ordered?

Your healthcare provider may order this test to evaluate risks for complications like preeclampsia, gestational hypertension, or poor placental development. It’s often used in the first trimester or during high-risk pregnancies to monitor blood flow and vascular health.

What Does a Result Mean?

Results are not typically interpreted alone but alongside other tests. Elevated levels may indicate early pregnancy or vascular health concerns, while very low levels could raise questions about placental function. Always discuss results with your provider.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The sample is processed into serum or plasma within 2 hours of collection for accurate measurement.

Common Uses and Considerations

This test is primarily used in obstetrics to monitor pregnancy-related vascular risks. It’s not a routine screening test but may be part of a broader evaluation for high-risk pregnancies.

Frequently asked questions

What is placental growth factor (PGF)?
PGF is a protein produced by the placenta that helps regulate blood vessel formation. It’s important for ensuring proper blood flow to the fetus during pregnancy.
How is PGF tested?
The test uses a specialized blood sample (serum or plasma) analyzed via a mass concentration method to measure PGF levels.
Can PGF levels change during pregnancy?
Yes, PGF levels naturally fluctuate during pregnancy. They may rise early in gestation and vary based on placental health, so results should be interpreted with other clinical factors.
