Our goal is to provide genetic testing for eyecare professionals as simply as possible. We also want to make
it easy to explain the AvaGen test to your patients.
That’s why Avellino offers materials and other resources to help support your practice. Review these
materials prior to testing and post-test.
If you are an eyecare patient, we invite you to visit our patient section.
