What is the normal level of anti-GAD antibodies?

The GAD antibody test results confirm the level of GAD antibodies in the blood. A normal result is under 5 units/ml. High levels of GAD antibodies often occur in people with a lower body mass index (BMI) and predict a more rapid progression toward requiring insulin.

What does positive insulin antibodies mean?

How can you tell the difference between type 1 and 2 diabetes?

The main difference between the two types of diabetes is that type 1 diabetes is a genetic disorder that often shows up early in life, and type 2 is largely diet-related and develops over time.

A GAD antibody test may be favoured as a way of testing for which type of diabetes over a c-peptide test,…

What is anti-glutamic acid decarboxylase (GAD) autoantibody?

A rare kind of antibody, known as anti-glutamic acid decarboxylase (GAD) autoantibody, is found in some patients. The antibody works against the GAD enzyme, which is essential in the formation of gamma aminobutyric acid (GABA), an inhibitory neurotransmitter found in the brain.
