GAD Ab

GAD Ab refers to an antibody called glutamic acid decarboxylase antibody. Glutamic acid decarboxylase (GAD) is an enzyme that is involved in the production of the neurotransmitter gamma-aminobutyric acid (GABA), which is important for regulating neuronal excitability in the central nervous system. GAD antibodies are autoantibodies that are produced by the body's immune system and are directed against GAD. Elevated levels of GAD antibodies are often found in individuals with autoimmune disorders such as type 1 diabetes, stiff person syndrome, and some forms of epilepsy.
