What is amniocentesis?
Amniocentesis is a diagnostic procedure where a small amount of amniotic fluid is taken from around the baby in the womb to test for chromosomal conditions, genetic disorders, or infections.
When is it performed?
Usually done between 15 and 20 weeks of pregnancy. It may also be performed later for specific concerns.
How is it done?
Using real-time ultrasound, a thin needle is carefully inserted through the abdomen into the amniotic sac to collect fluid.
What conditions can it detect?
It can detect genetic conditions - aneuploidies like down syndrome, spinal muscular atrophy, thalassemia and intrauterine infections.
Is it safe?
Yes. The risk of miscarriage is very less at 0.2 - 0.3 percent
How soon are results available?
The time it takes to receive your results will depend on what tests the lab needs to conduct on the amniotic fluid.
You may hear some information from your doctor as soon as 1 week after your test. Some test results may take 2 weeks or longer.
