PATHOLOGY

Detailed explanation-1: -Genetic testing is a type of medical test that identifies changes in genes, chromosomes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder.

Detailed explanation-2: -Genetic testing involves examining your DNA, the chemical database that carries instructions for your body’s functions. Genetic testing can reveal changes (mutations) in your genes that may cause illness or disease.

Detailed explanation-3: -Chorionic villus sampling and amniocentesis are two methods of confirming the diagnosis of a chromosomal abnormality when the screening test is positive. Both of these tests carry a small risk of miscarriage. Many parents want to know this information so they can make informed decisions about their pregnancy.

Detailed explanation-4: -Chromosome analysis or karyotyping is a test that evaluates the number and structure of a person’s chromosomes in order to detect abnormalities. Chromosomes are thread-like structures within each cell nucleus and contain the body’s genetic blueprint.
