Best Genetics in Chennai

A DNA test (genetic testing) is a medical test that can identify mutations in your genes, chromosomes or proteins. These mutations can indicate if you have or don’t have a genetic condition. DNA tests can also identify your risk for developing a certain condition or passing on a genetic disorder.

What is genetic testing?
Genetic testing may also be called DNA testing. It’s a type of test that can identify changes in the genes, chromosomes or proteins in your body. Genetic testing takes a sample of your blood, skin, hair, tissue or amniotic fluid. The test may be able to confirm or rule out if you have a genetic condition. It may also help determine your chances of developing or passing on a genetic disorder.

What does genetic testing look for?
Genetic testing looks for changes in your genes, chromosomes and proteins. DNA tests can give you lots of information about the genes that make up who you are. They can confirm if you have or don’t have a specific disease. They can determine if you have a higher risk of developing certain conditions. And they can find out if you carry a specific mutated gene that you can pass to your child.

What are the different types of DNA tests?
The various types of genetic tests include tests that look at:

Genes: Gene tests analyze your DNA to find changes (mutations) in your genes that can cause or increase your risk of developing a genetic disorder. Gene tests may study one gene, a few genes or all your DNA. Looking at all your DNA is called genomic testing.

Chromosomes: Chromosomal tests study your chromosomes or long strings of your DNA. They look for changes in the order of genes that could be the cause of a genetic condition. One example of the changes looked for is an extra copy of a chromosome.

Proteins: Protein tests analyze the enzyme activity in cells, looking for the products of chemical reactions in our cells. Problems with your proteins can mean you have changes in your DNA that can cause a genetic condition.
