# Genetic Testing

## What is a genetic test?

 A genetic test examines a person’s DNA to identify changes or mutations that may indicate a genetic disorder. The test usually involves taking a sample of blood, saliva, hair, or skin cells and sending them to an authorised laboratory for analysis. Genetic testing can be used to detect a variety of conditions, including chromosome abnormalities, inherited diseases, and cancer. It can also be performed during pregnancy to screen for certain disorders and assess the risk of passing on a disease to future children. Genetic testing is generally considered safe, but it can have some risks depending on the type of test and results.

 

## How does a genetic test work?

 A genetic test examines your DNA, the chemical database that carries instructions for how your body functions. The test looks for changes or mutations in your genes that can cause disease or predispose you to certain illnesses.

 A sample of your blood, saliva, hair or skin is taken and sent to an authorised lab for testing. The lab analyses your DNA using methods such as polymerase chain reaction (PCR) and microarray.

It can also be used to screen unborn babies for genetic conditions before they are born. This is known as prenatal testing or newborn screening. The results of a genetic test are then reported to your doctor who can discuss them with you and recommend any further action, such as counselling.

 

## What are the benefits of a genetic test?

 Genetic tests can help you learn more about your health. They can also reveal important information about your family’s health. This can help you make decisions about your medical treatment and plan for the future. There are different types of genetic tests available, depending on your symptoms and goals. One type of genetic test is called diagnostic testing, which checks for specific diseases or conditions. Another is carrier testing, which checks for genes that may be linked to genetic disorders. This type of test can be done at any time, including before pregnancy with a blood test or mouth swab.
