How is an amniocentesis DNA test performed?

During an amniocentesis DNA test, the doctor inserts a thin needle in the uterus to obtain a small amount of amniotic fluid from the sac surrounding the fetus. The amniotic fluid collected is used as a sample to conduct the test in the laboratory to look for genetic conditions and other kinds of potential issues that might cause harm to your child’s health.


  • Firstly the doctor will use an antiseptic to clean a small area of your abdomen.
  • Then they will apply a specific gel to your stomach.
  • The doctor then uses an instrument over the gel to collect ultrasound images of the fetus, and observe the images displayed on a nearby monitor.
  • Then the slender, hollow needle is inserted into the abdomen and uterus which is used to remove a small amount of amniotic fluid.
  • After the needle is removed the ultrasound monitors your baby’s heartbeat and activity to confirm that they were not impacted by the process.
  • Following the procedure, your healthcare professional sends the amniotic fluid sample to a laboratory for analysis.
