Detailed explanation-1: -Amniocentesis can be done for a number of reasons: Genetic testing. Genetic amniocentesis involves taking a sample of amniotic fluid and testing the DNA from the cells for diagnosis of certain conditions, such as Down syndrome. This might follow another screening test that showed a high risk of the condition.

Detailed explanation-2: -Amniocentesis, chorionic villus sampling (CVS) and ultrasound are the three primary procedures for diagnostic testing. Amniocentesis is the test we most commonly use to identify chromosomal problems, such as Down syndrome.

Detailed explanation-3: -Amniocentesis is usually carried out between the 15th and 20th weeks of pregnancy, but you can have it later if necessary. It can be performed earlier, but this may increase the risk of complications of amniocentesis and is usually avoided.

Detailed explanation-4: -Screening for Down syndrome can be performed as early as 11 to 14 weeks of pregnancy with a first trimester ultrasound and blood test. Screening can also be performed between 15 and 20 weeks by a blood test referred to as the multiple marker serum screening test.

Detailed explanation-5: -Amniocentesis is a prenatal procedure that your doctor may recommend you have during pregnancy. The test checks for fetal abnormalities (birth defects) such as Down syndrome, cystic fibrosis or spina bifida. In most cases, the results are normal. Amniocentesis is performed between 16 and 20 weeks into the pregnancy.
