What technique is used for obtaining foetal cells for chromosome analysis?
That sounds like either amniocentesis or chorionic villus sampling.
What is A process where a long thin tube is used to withdraw fetal cells from the fetal side of the placenta is?
It is called chorionic villi sampling.
What sampling CVS is performed between the eigth and tenth weeks of pregnancy to search for genetic abnormalities in the developing fetus?
Chorionic villus sampling, CVS, is performed between the eighth and tenth weeks of pregnancy to search for genetic abnormalities in the developing fetus.
How do core samples help geologists?
Geologic core sampling serves a number of important purposes, such as giving scientists information regarding variations of climate. It also provides information about sedimentary composition, and various species.
Can down's syndrome be detected through a pregnant mothers chromosomes via karyotyping rather than amniocentesis?
A normal human male has two 21st chromosomes and a Down Syndrome male has three 21st chromosomes. A human female would have the same karotype with regard to chromosome 21 as a male human.
What technique is used for obtaining foetal cells for chromosome analysis?
That sounds like either amniocentesis or chorionic villus sampling.
What advantage does chorionic villi sampling have over amniocentesis?
yes
What are the two methods of prenatal diagnosis?
Amniocentesis and chorionic villi sampling.
Do amniocentesis and chorionic villus sampling allow for karyotyping and biochemical testing of the fetus?
yes
A method used to determine the karyotype of a fetus is called what?
amniocentesis
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.
How is the decision to perform prenatal surgery made?
Ultrasound, amniocentesis or chorionic villi sampling checks for chromosomal abnormalities in the fetus.
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.
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 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.
What are the two procedures used to obtain the cells needed for preparing a fetal karyotype?
CVS (Chorionic Vili Sampling) and Amniocentesis. (High School Biology Student)
