What Is This Test Meant to Detect?

Amniotic fluid contains cells from both the fetus and the mother. This test examines these cells for signs of abnormalities, such as fetal distress, infection, or structural issues. The presence of certain cells (e.g., fetal cells, inflammatory cells) can indicate underlying conditions that may require further evaluation.

Why Might This Test Be Ordered?

Your healthcare provider may recommend this test if you have symptoms like decreased fetal movement, concerns about pregnancy complications, or if prenatal testing suggests potential risks. It can also be part of a routine evaluation in high-risk pregnancies.

How Is the Test Performed?

A small sample of amniotic fluid is collected via amniocentesis—a procedure where fluid is gently extracted from the amniotic sac. The sample is then examined under a microscope by a trained technician to count and identify different cell types.

What Are the Possible Results?

Results may show normal cell counts (indicating healthy fetal development) or abnormal findings (e.g., high levels of certain cells that could signal infection, bleeding, or other issues). Exact interpretations depend on clinical context and your healthcare team’s assessment.

Frequently asked questions

How often will I need this test?
This test is typically performed once during pregnancy, often between 15 and 28 weeks, but timing depends on your medical history and symptoms. Your provider will discuss the best schedule with you.
What do abnormal results mean?
Abnormal results may raise concerns about fetal health, such as signs of infection (e.g., elevated white blood cells), bleeding, or other complications. Your provider will review the results with you and recommend next steps, which could include additional tests or monitoring.
Is there any risk involved with this procedure?
The procedure carries very low risk, but possible risks include infection or injury to the uterus. Your healthcare provider will explain the benefits and risks before proceeding.
