What else can I help you with?
Do amniocentesis and chorionic villus sampling allow for karyotyping and biochemical testing of the fetus?
yes
What advantage does chorionic villi sampling have over amniocentesis?
yes
What are the two methods of prenatal diagnosis?
Amniocentesis and chorionic villi sampling.
When is Chorionic villus sampling done?
Chorionic villus sampling can be done at the 8th week. Amniocentesis cannot be performed until the 14th week of pregnancy.
What technique is used for obtaining foetal cells for chromosome analysis?
That sounds like either amniocentesis or chorionic villus sampling.
How is the decision to perform prenatal surgery made?
Ultrasound, amniocentesis or chorionic villi sampling checks for chromosomal abnormalities in the fetus.
A method used to determine the karyotype of a fetus is called what?
The method used to determine the karyotype of a fetus is called chorionic villus sampling (CVS) or amniocentesis, in which fetal cells are obtained for genetic analysis. These tests can reveal the number and structure of chromosomes in the fetus, helping to diagnose genetic disorders and abnormalities.
What are the two procedures used to obtain the cells needed for preparing a fetal karyotype?
The two procedures used to obtain cells for preparing a fetal karyotype are chorionic villus sampling (CVS) and amniocentesis. CVS involves taking a sample of cells from the placenta, while amniocentesis involves collecting cells from the amniotic fluid surrounding the fetus.
How is a diagnosis of Niemann-Pick disease confirmed in a pregnant women?
Prenatal diagnosis of Types A and B of NPD can be done with amniocentesis or chorionic villus sampling.
What tests can confirm the presence of Tay-Sachs disease in a fetus?
Amniocentesis or chorionic villi sampling can be used to determine if the fetus has Tay-Sachs disease.
What care should a patient receive after an amniocentesis?
Chorionic villus sampling, amniocentesis and bone marrow procedures are done under a physician's supervision. The person is asked to rest after the procedure and is watched for weakness and signs of bleeding.
What out-patient procedures can be helped by using a pelvic ultrasound?
Doctors may use ultrasound to guide the biopsy needle during amniocentesis and chorionic villus sampling.
