Universal Test
About Universal Test
Universal Test is a genetic test that can detect five genetic mutations related to corneal dystrophy and has 100% sensitivity and specificity as clinically shown via a large clinical trial in Korea related to corneal dystrophy. (Yonsei University Health System, Severance Hospital, Institutional Review Board.)
Avellino Lab protected 1,845 people with
corneal dystrophy mutations from vision loss.1
What is Corneal Dystrophy?
Corneal dystrophy is a common ophthalmic genetic disease caused by genetic mutations. With certain types of corneal dystrophy, various forms of grayish-white proteins accumulate as the cornea heals after damage. This leads to reduced eyesight and the loss of vision in extreme cases.
Corneal dystrophy usually manifests between childhood and young adulthood: however, symptoms can appear late in one’s thirties due to genetic and environmental differences. In addition, the correlation between the disease and the age of onset is hard to predict as the age of onset varies widely even within families with the same genetic mutation.
Avellino Lab Universal Test detects the five types of corneal dystrophies.
Granular Corneal Dystrophy Type 1
Granular Corneal Dystrophy Type 2 / Avellino Corneal Dystrophy
Lattice Corneal Dystrophy Type 1
Reis-Bücklers’ Corneal Dystrophy
Thiel-Behnke Corneal Dystrophy
