Why This Test Is Done

Doctors may order this test if there are concerns about fetal metabolic health, such as gestational diabetes, obesity, or other conditions that could affect lipid levels. It may also be part of routine prenatal screening in certain cases.

What to Expect During the Test

A small blood sample is taken from your arm. The sample is then processed to measure cholesterol and triglycerides in fetal serum. Results are typically reported as part of a broader prenatal assessment.

How Results Are Interpreted

While specific reference ranges vary by lab, elevated or low levels of fetal cholesterol or triglycerides may signal potential metabolic concerns. Your healthcare provider will discuss findings in the context of your overall health and pregnancy.

Common Causes for Testing

Testing may be prompted by maternal conditions like high blood pressure, diabetes, or obesity, or if there are signs of fetal growth issues. It can also be part of genetic or metabolic screening programs.

Reference range

Adult males: 7-56 U/L; Adult females: 7-43 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.
