A doctor can often make an initial diagnosis of Down syndrome at birth based on how the baby looks. The doctor may hear a heart murmur when listening to the baby's chest with a stethoscope.
|
 |
Diagnosis is usually suspected at birth, when the characteristic physical signs of Down syndrome are noted. Once this suspicion has been raised, genetic testing (chromosome analysis) can be undertaken in order to verify the presence of the disorde...

Karyotyping is a test to examine chromosomes in a sample of cells, which can help identify genetic problems as the cause of a disorder or disease. This test can: Count the number of chromosomes; Look for structural changes in chromosomes.
|
|
Karyotype refers to the arrangement of chromosomes in their matched (homologous) pairs. For the purposes of this definition, we will be referring to human chromosomes, although there is a karyotype characteristic for each species. The human chromo...

Chorionic villus sampling (CVS) is the removal of a small piece of placenta tissue (chorionic villi) from the uterus during early pregnancy to screen the baby for genetic defects.
|
|
Chorionic villus sampling (CVS) is a prenatal procedure for the removal by needle of chorionic villi and culture and examination of the fetal cells obtained. The cells are used in tests for genetic and chromosomal abnormalities of a fetus as early...

 |
Chorionic villus sampling (CVS), also known as chorionic villus biopsy, is a prenatal test that can detect genetic and chromosomal abnormalities of an unborn baby.

The triple marker screen test (also called the maternal serum screening test or multiple marker test), is a blood test that is performed usually between the 14th and 18th week of pregnancy . This screening test measures the levels of three substan...

A quantitative human chorionic gonadotropin (HCG) test measures the specific level of HCG in the blood. HCG is a hormone produced during pregnancy. See also: HCG urine test; HCG blood test - qualitative.

Alpha fetoprotein (AFP) is a protein normally produced by the liver and yolk sac of a fetus. AFP levels decrease soon after birth. AFP probably has no normal function in adults. A test can be done to measure the amount of AFP in your blood. See al...

The alpha-fetoprotein (AFP) test is a blood test that is performed during pregnancy to screen the fetus for certain conditions; it is also used to screen for certain diseases in infants and children. The screening test measures the level of AFP in...

Prenatal test that tests for birth defects. The Alpha Fetoprotein (AFP) Test is a commonly used prenatal test to monitor the level of AFP—a possible indicator of developmental abnormalities—in the liver of a fetus during high-risk pregnancies. The...

Amniocentesis is a test during pregnancy that removes a small amount of fluid from the sac around the baby to look for birth defects and chromosome problems.
|
 |
Amniocentesis is a procedure used to diagnose fetal defects in the early second trimester of pregnancy . A sample of the amniotic fluid, which surrounds a fetus in the womb, is collected through a pregnant woman's abdomen using a needle and syring...

Amniocentesis is an optional procedure offered to women during pregnancy in order to obtain more information about a developing fetus. A doctor uses a thin, hollow needle to remove a small sample of amniotic fluid from around the developing baby. ...
