How to Understand the Results of an Amniocentesis

Your obstetrician will explain the results of the amniocentesis to you. But here are a few guidelines.

Instructions

1. Understand that normal amniotic fluid is clear. It may contain a few white flecks later on in the pregnancy. Blood in amniotic fluid usually belongs to the mother and is not generally something to worry about.

2. Understand that the presence of feces in the amniotic fluid in the third trimester may mean fetal distress.

3. Understand that chromosomes from the amniotic fluid will be analyzed for Down's syndrome and that levels of alpha-fetoprotein will be measured to check for spina bifida - amniocentesis is 100 percent effective in detecting them.

4. Understand that chromosomal analysis will reveal the sex of the baby and help pinpoint any sex-related diseases such as hemophilia.

5. Understand that other genes will be analyzed to detect substances that relate to developmental and metabolic disorders.

6. Be patient. The results from amniocentesis may take up to two weeks. Your obstetrician will want to meet with you in person to discuss the results.

7. Understand that amniocentesis will not always be able to determine if your baby will be healthy. A normal amniocentesis does not guarantee a normal baby.

Tips & Warnings

• Consider Chorionic Villi Sampling if you are concerned about a possible genetic disorder or birth defect. Similar to amniocentesis, it can be performed earlier in the pregnancy, and results are available sooner.

• If you have any questions or concerns, contact a physician or other health care professional before engaging in any activity related to health and diet. This information is not intended as a substitute for professional medical advice or treatment.
