amniocenteses, plural;
  1. The sampling of amniotic fluid using a hollow needle inserted into the uterus, to screen for developmental abnormalities in a fetus

  1. (pregnancy) extraction by centesis of amniotic fluid from a pregnant woman (after the 15th week of pregnancy) to aid in the diagnosis of fetal abnormalities
  2. Amniocentesis (also referred to as amniotic fluid test or AFT), is a medical procedure used in prenatal diagnosis of chromosomal abnormalities and fetal infections , in which a small amount of amniotic fluid, which contains fetal tissues, is extracted from the amnion or amniotic sac surrounding ...
  3. A procedure for obtaining amniotic fluid from a pregnant animal, by inserting a hollow needle through the abdominal wall and into the amniotic sac. Used in diagnosing possible genetic defects and/or obstetric complications
  4. A prenatal test to detect birth defects that is performed after the 15th week of pregnancy. It involves inserting a needle through the abdomen to retrieve fluid that contains placental cells.
  5. If necessary, this test is performed between 15 and 20 weeks of pregnancy and can indicate chromosomal abnormalities such as Down syndrome, or genetic disorders such as Tay Sachs disease, sickle cell disease, cystic fibrosis, and others. ...
  6. A prenatal test in which cells surrounding a fetus are removed in order to examine the chromosomes.
  7. A method of prenatal testing in which amniotic fluid is withdrawn from the uterus through a needle. The fluid and the fetal cells it contains are analyzed to detect biochemical or chromosomal disorders.
  8. Amniocentesis is a procedure performed on some pregnant women. It is used to screen for or diagnose different conditions of the fetus. A doctor will use a needle guided by ultrasound to take a sample of the fluid that surrounds the fetus within the uterus. ...
  9. A test where amniotic fluid is aspirated to test the fetus for genetic abnormalities.
  10. Transabdominal aspiration of fluid from the amnionic sac surrounding the developing fetus. Cells within the fluid are cultured in vitro and analyzed to detect genetic abnormalities in the fetus.
  11. A screening or diagnostic procedure during which a sample of amniotic fluid surrounding the developing fetus is withdrawn by means of an ultrasound-guided needle. The amniotic sac is a fluid-filled membrane that surrounds and protects the developing fetus within the uterus. ...
  12. A prenatal test in which a small amount of amniotic fluid is removed for analysis.
  13. A procedure in which a small amount of amniotic fluid is taken from the sac surrounding the fetus and tested.
  14. A medical procedure in which cells from the fetus are obtained from the fluid within the innermost fetal membrane.
  15. (am-nee-oh-sen-TEE-siss) — Also called amnio. A test that takes some amniotic fluid from around your baby in the uterus. The test checks for problems with the baby, like birth defects or genetic problems. You can get this test at 15 to 20 weeks of pregnancy.
  16. removal of amniotic fluid by syringe placed through uterus and amniotic membrane for the use of genetic testing or testing of fetal lung maturity.
  17. A diagnostic test for finding genetic fetal abnormalities such as Down Syndrome. It is usually done between 15 to 18 weeks of pregnancy. It is done by removing a small amount of amniotic fluid using a needle under ultrasound guidance.
  18. Amniocentesis is a diagnostic procedure that is performed during pregnancy based on the recommendation of the doctor or genetic counselor. ...
  19. a method for detecting genetic diseases in unborn babies. A needle is inserted through the mother's abdomen to remove fluid from the sac surrounding the fetus in the mother's womb; the fluid and the cells in the fluid can be examined to see if the baby will have a genetic disorder.
  20. A procedure for obtaining amniotic fluid from a pregnant mammal for the diagnosis of some diseases in the unborn foetus. Cells are cultured, and metaphase chromosomes are examined for irregularities (e.g., Down syndrome, spina bifida, etc., in humans).
  21. A process by which the amniotic (or fetal) sac is punctured by a needle and fluid removed. The amniotic fluid removed can then be studied for detection of neural tube defects and chromosomal abnormalities before the baby is born.
  22. withdrawal of a sample of fluid contained in the pregnancy sac
  23. a way of checking a pregnancy to see if the fetus has some birth problems, including chromosomal disorders, biochemical disorders and gene abnormalities. A needle is inserted into the mother's abdomen and a small amount of amniotic fluid (containing amniotic cells) is removed for testing. ...
