If you test for it in pregnancy the test is called a CVS or an Amniocentesis. They test the amniotic fluid or a piece of the babys' placenta for the third 21st chromosome.
After birth, they take some blood from the baby and run what is called a Karyotype. That test will count the chromosomes in the cells of the blood and if there are 3 21st chromosomes that means Down syndrome
What else can I help you with?
What procedure can be preformed during fetal development to detect down syndrome?
amniocentesis
Will a laboratory test for Down syndrome pick up marijuana in your system?
If the test for this syndrome is a blood test then, maybe. A blood test will detect marijuana. A urine test will also detect marijuana.
What can karyotype analysis detect?
Karyotype analysis can be used to easily determine sex and a number of genetic disorders, such as Down's Syndrome (trisomy-21) or Klinefelter's Syndrome (XXY).
What can be diagnosed by examining a karyotype of an individuals white blood cells?
A karyotype of an individual's white blood cells can be used to diagnose chromosomal abnormalities such as Down syndrome, Turner syndrome, and Klinefelter syndrome. It can also detect genetic disorders caused by aneuploidy or large structural chromosomal changes.
Can a congenital disorder be diagnosed by amniocentesis?
Amniocentesis primarily is looking at the DNA. It can detect major genetic problems like Down's syndrome.
What information can be obtained about a fetus from a karyotype?
A karyotype can provide information about the number, size, and shape of an individual's chromosomes. This can help detect chromosomal abnormalities such as Down syndrome or Turner syndrome in a fetus.
What is the genetic disorder for having three 21 chromosomes?
down syndrome
What does the triple marker screen detect?
Triple-Marker tests for congenital defects such as Neural Tube defects (spina bifida, myelo/meningocelle), Edward's syndrome (Trisomy 18), and Down Syndrome (Trisomy 21).
What is a chromosomal disorder that could result from nondisjunction?
Disorders, such as Down's Syndrome, are caused by nondisjunction.
What is the correct spelling 'Down syndrome' or 'Down's syndrome'?
Down syndrome is generally the preferred spelling, although Down's syndrome is sometimes used in American sources.
Is down's syndrome inherited?
Most cases of down syndrome are not inherited. Translocation Down syndrome can be inherited.
Is there a test to detect angelman syndrome?
molecular genetic testing?
