Why Is This Test Done?

Your healthcare provider may order this test if you have concerns about your pregnancy, such as signs of preterm labor, infection, or other complications. It can also be part of a routine evaluation in certain high-risk pregnancies.

What Does a High or Low Cell Count Mean?

A higher-than-expected cell count might suggest fetal distress, infection, or other issues that require further medical evaluation. A lower-than-expected count could indicate fewer cells, which may need additional investigation depending on clinical context.

How Is the Test Performed?

Amniotic fluid is typically collected through an amniocentesis procedure, where a small amount of fluid is extracted from around the fetus. The collected fluid is then sent to the lab for cell counting.

What Are the Possible Results?

Results are usually reported as a cell count per milliliter or microliter of fluid. Interpretation depends on clinical context, including your medical history and symptoms.
