Detailed explanation-1: -Karyotyping is a test used to identify chromosome abnormalities as the cause of malformation or disease. The test can be performed on a sample of blood, bone marrow, amniotic fluid, or placental tissue.
Detailed explanation-2: -A karyotype test checks the chromosomes in your cells to: See whether you have a full set of 46 chromosomes. Having too many or too few chromosomes can cause serious problems with health, growth, and normal development, such as Down syndrome (extra chromosome 21) and Turner syndrome (missing X chromosome).
Detailed explanation-3: -During division, the chromosomes in these new cells line up in pairs. A karyotype test examines these dividing cells. The pairs of chromosomes are arranged by their size and appearance. This helps your doctor easily determine if any chromosomes are missing or damaged.
Detailed explanation-4: -Examples of conditions that cannot be detected by karyotyping include: Cystic fibrosis. Tay-Sachs disease. Sickle cell disease.
