Fetal Total Cholesterol from Gestational Age (Serum/Plasma)

Why Is This Test Done?

Your healthcare provider may order this test if you have concerns about fetal growth, genetic conditions, or if you’re at higher risk for complications like preterm birth or fetal distress. It may also be part of routine prenatal screening in certain cases.

What Does the Test Involve?

A small blood sample is collected from your baby during a procedure called a **cordocentesis** (performed under ultrasound guidance) or, less commonly, from a fetal blood sample obtained during a procedure like amniocentesis. The sample is sent to a lab for analysis.

What Are Common Uses?

Fetal cholesterol testing can help evaluate fetal cardiovascular development, identify metabolic disorders, or monitor high-risk pregnancies. It may also be used to assess fetal response to medications or genetic conditions affecting lipid metabolism.

What Might Abnormal Results Indicate?

Elevated or low fetal cholesterol levels may signal underlying conditions such as genetic disorders (e.g., Smith-Lemli-Opitz syndrome), metabolic diseases, or fetal exposure to certain medications. Your provider will discuss findings in the context of your pregnancy and medical history.
