The GAD 65 antibody blood test is a simple blood test that doesn’t require much preparation. Unlike some other tests, the GAD 65 antibody total doesn’t require fasting. Your blood sample will be collected by a healthcare provider from the vein in your arm.
The parameters of a GAD 65 antibody total examination are glutamic acid decarboxylase or GAD-65 antibodies. They belong to a group of diabetes-associated antibodies that instruct the immune system to demolish the insulin-producing pancreatic cells. When insulin production stops, diabetes tends to develop.
The GAD 65 antibody is also a biomarker of other autoimmune disorders like pernicious anaemia and thyroid disease.
A random GAD 65 antibody total helps with the diagnosis of latent autoimmune diabetes. It belongs to the type 1 diabetes family that develops in individuals after a certain age. Additionally, the GAD 65 antibody total also serves as a marker of the proneness to other autoimmune diseases like thyroid disease, pernicious anaemia or Addison disease.
If the GAD 65 antibody total results confirm the diagnosis of diabetes, your doctor will prescribe appropriate medication to you. The test can be repeated after 5-6 months to check the level of GAD antibodies in the blood.
