Genetic testing is examining a person’s DNA for changes, variants or mutations that can lead to severe medical conditions or diseases. DNA is defined as a self-replicating chemical database that carries genetic information and is also considered to contain all information that is necessary to develop and maintain an organism.
The process of analyzing DNA from a sample of blood is known as genome sequencing, and this process is usually offered by specialized facilities whenever genetic testing does not lead to a clear diagnosis.
It is a widely used medical diagnostic tool for detecting any genetic risks towards certain medical conditions. It also helps physicians in determining the best course of treatment and medication. Medical practitioners across the globe widely use genetic testing, and it’s increased usage has led to the early detection of several medical conditions like cystic fibrosis, sickle cell anemia and thalassemia.
Depending on the type of illness or condition that needs to be diagnosed, there are different types of genetic testing used by doctors and physicians:
Preparation for genetic or DNA testing primarily requires an open discussion with the patient’s family about the possibilities of the test results impacting them. It’s also important to know that certain types of DNA testing may not be eligible for health insurance policies, so it’s important to discuss your plans for getting a genetic test with a physician.
Most types of DNA or genetic testing carries minimal risks, as DNA samples are collected through mouth swabs. But certain types, like amniocentesis, can carry a slight risk of miscarriage.
More than physical risks, the emotional impact of a genetic test on an individual cannot be understated. Hence, it is always recommended to discuss such tests with a physician before going through with them.
The time for getting the results from a DNA test varies on the type of test administered and the facility from which it was performed. We can classify these results into two categories – positive and negative.
If you have a family history of genetic conditions, or suspect the presence of a genetic condition, or even have an interest in understanding your genes or if you’re predisposed to certain medical conditions, genetic testing is an option to try out. To understand this testing program in more detail, you can consult your physician at the nearest Apollo Hospitals.
