Chromosome Analysis -- See Karyotyping.
Chorionic Villae Sampling (CVS) -- An alternative to amniocentesis that can be done earlier in the pregnancy. It is a biopsy of the placenta that is used to check for genetic abnormalities in the fetus.
Chromosome analysis can be performed from a small blood sample to rule out the presence of a chromosome abnormality in a child with a congenital heart defect.
Single gene defects: ...
Chromosome Analysis (Karyotyping)
A chromosome analysis in which cells are studied to look for certain congenital diseases such as Down's syndrome or spina bifida.
A chromosome analysis in which cells are studied to look for abnormalities. Testing a fetus may show if there is a chromosomal reason for the pregnancy loss, which causes about 50% of miscarriages.
Karyotype (chromosome analysis) or genetic test
Karyotyping is a blood test that looks for problems in the genetic material (chromosomes Opens New Window) in your cells. Some genetic problems make it hard to become pregnant or cause miscarriages.

Fetal cells from the skin, bladder, and gastrointestinal tract are in the fluid and can be grown for chromosome analysis. Results of the testing are usually available within two weeks.
If the amnio is taken for chromosome analysis or molecular DNA analysis, it is typically performed between 16 and 18 weeks of pregnancy. In some cases, however, the test may be done up to a month earlier.
Blood tests from both partners for chromosome analysis;
A hysterosalpingogram to evaluate the uterus;
Blood tests from the female for Prolactin, TSH, lupus anticoagulant and anticardiolipin antibodies; and ...
When PUBS is used for chromosome analysis, the results are usually ready much faster than with amniocentesis. With PUBS, the results may be ready within 48 hours. With amniocentesis, results can take about two weeks.
What Are The Risks?
Extended banding or "high resolution" chromosome studies means that the chromosomes are studied at a higher resolution than the standard chromosome analysis mentioned above.
Complete moles often have a diploid (double) karyotype (chromosome analysis) 46,XX due to fertilisation of an empty egg by a single sperm followed by reduplication of the haploid (single) chromosome. ...
Pericentric inversion of the y chromosome is usually a familial variant of no known clinical significance occurring in 1 in 1000 males. A chromosome analysis of the father's blood may be performed to determine if this Y chromosome is inherited ( 5 mL ...
If behavior problems related to FASD are suspected in an older child, the parents and/or teachers (or day care providers) may be asked to complete a behavior checklist questionnaire. A chromosome analysis, genetic testing, ...
Samples and donors are screened continually for sexually transmitted diseases and genetic issues. Additionally, all donors are screened for cystic fibrosis and undergo chromosome analysis (karyotyping).
Percutaneous umbilical cord sampling (PUBS) - A procedure in which a blood sample is withdrawn from the umbilical cord while the fetus is still in the uterus; used mainly for rapid chromosome analysis or to evaluate fetuses at risk for certain ...
Percutaneous Umbilical Blood Sampling - A procedure in which blood is drawn from the cord while the baby is still in the womb to test for blood disorders or for rapid chromosome analysis.
pregnancy can also give information about the possibility of Turner syndrome, but ultrasound is not 100 percent accurate, and many babies with Turner syndrome may look the same on ultrasound as those without Turner syndrome. A chromosome analysis, ...
Serum chromosome analysis revealed a normal 46, XY male. Unfortunately, the patient was lost to follow-up and did not return for evaluation until he was 27 months of age despite numerous attempts to contact the family.
X-ray and ultrasound studies of the uterus may be ordered to look for tumors or foreign objects which might distort the internal cavity of the uterus. Hormone levels, pregnancy tests, and even chromosome analysis may be necessary for a complete ...
