What is genetic testing?

A genetic test analyzes your DNA–the chemical building blocks of genes–to look for changes (mutations) that can cause certain diseases. Not only can genetic testing lead to a diagnosis of certain diseases, but it can also help detect certain risk factors that may tell you if you are likely to develop a disease.

  • There are many ways to conduct a genetic test; with the AvaGen test from Avellino, a simple swab of the inside of your cheek is all it takes
  • The swab collects a sample of cells that is then transferred to a vial containing a preservative solution. This sample is then sent to our lab where Avellino sequences the genes and identifies mutations that may indicate a disease or a risk for a disease

If your eyecare professional is able to diagnose, treat, or manage your disease earlier, it may make a big difference to your overall eye health and vision.

Talk to your physician or eyecare professional about testing.

Why should I get my eyes tested?

Genetic testing is an important step in diagnosing diseases, such as keratoconus or corneal dystrophies. When your doctor suspects that you may have a genetic disease or could develop one in the future, it’s important to get tested so you can confirm a diagnosis or risk factors and take appropriate steps.

These steps might include treatment or preventive measures, such as not rubbing your eyes or avoiding certain types of eye surgery, which could make your condition worse.

Remember, the earlier you identify a disease, the more opportunities you may have to treat the disease or slow the progression.

How do I get tested?

Ask your doctor to order the AvaGen genetic test. After your doctor sends your sample to the lab, you may get results back as quickly as 5 days.

If your test confirms a risk for developing keratoconus or the presence of corneal dystrophy, you and your doctor may consider creating a management or treatment plan. You might also want to speak with a genetic counselor.

Avellino provides a network of genetic counselors if your test results reveal a risk or positive results. These counselors work with you and your doctor to provide further details that could help you moving forward.
