Description
Karyotyping makes it possible to identify physiological features and pathological defects in human genes.
The study is widely used to diagnose genetic diseases. The sampling of amniotic fluid, followed by karyotypes, will help diagnose fetal chromosomal pathology.
If severe pathological changes are found in the fetus, the question may arise of terminating the pregnancy for medical reasons.
When and who needs the test?
Identification of congenital and hereditary diseases (study of the karyotype of the cells obtained, determination of the number of chromosomes and their structure), adverse results of the screening study (deviations on ultrasound, in the biochemical analysis of blood – a ‘triple’ or ‘double’ test), the woman’s age (at 35 and more years, the risk of having a child with chromosomal abnormalities increases), the birth of a child with a history of hereditary pathology, a burdened family history (the spouses have relatives with hereditary diseases or chromosomal abnormalities).
