Amniocentesis: The risks

Amniocentesis is not without risk for the fetus. The risk of miscarriage is estimated to be between 0.5% and 0.9%.

The puncture may be white, that is to say do not bring liquid. It can also contain blood, which makes it uninterpretable. It must be avoided, of course, that the needle does not touch the placenta, the cord or the fetus.

In some cases, amniocentesis is difficult to practice when the placenta is placed in front of the uterus, for example. Fetal red blood cells can pass into the maternal bloodstream.

This is an intrusive gesture, which can, in very rare cases, cause infections.

In women with AIDS or hepatitis B, amniocentesis may be at risk of transmitting the disease to the fetus.

However, amniocentesis is nowadays a frequent and well-controlled examination by practitioners.

Amniocentesis is performed as an outpatient (without requiring hospitalization). However, expectant mothers are advised to rest for a few hours after the examination, which may cause contractions.

The results are reliable but not 100%. There is always a (small) margin of error.
