Fluid taken from sac: Amnio is a test done at 15-20 wks of pregnancy to check if a fetus has a genetic disorder like down's syndrome.It is usually done for women >35 y/o or with a previous abnormal screening test like an msafp test or NT test.An ultrasound is done 1st to check the fetus, the fluid and placenta.A very thin needle is used to remove the fluid with ultrasound guidance.Anesthesia usually not needed.
