The GAD-65 Antibody, also known as Glutamic Acid Decarboxylase 65 Antibody, is a protein that your body may create in response to certain triggers. This antibody targets an enzyme found in nerve cells and in the cells of the pancreas that produce insulin. The GAD-65 enzyme has an important role in the nervous system by helping to change glutamate, a brain chemical, into a less stimulating substance called GABA. This transformation process is crucial for keeping the right balance of activity in your brain and nervous system. In the pancreas, GAD-65 is essential for the normal functioning of cells that make insulin, which plays a significant part in managing sugar levels in the body.
If Your Levels Are High
Elevated GAD-65 Antibody levels suggest that your body is reacting to the GAD-65 enzyme, which is important for both brain function and insulin production. This immune response might be triggered by various factors, such as certain medications, environmental influences, or health conditions. As a result, the normal functioning of nerve cells and insulin-producing cells in the pancreas could be affected, potentially leading to imbalances in brain activity and blood sugar regulation. Some possible causes for high GAD-65 Antibody levels include autoimmune disorders like type 1 diabetes or neurological conditions like Stiff Person Syndrome.
Symptoms of High Levels
Symptoms of high levels of GAD-65 Antibody could include fatigue, difficulty concentrating, mood changes, unexplained weight loss, frequent urination, and increased thirst.
If Your Levels are Low
If your GAD-65 Antibody levels are lower than normal, it might mean that your body isn't making enough of this particular antibody. This could happen for various reasons, such as your immune system not working as it should, or it might be related to certain medications that can affect antibody production. Low levels of GAD-65 Antibody could also be connected to problems with your nervous system or how your body handles sugar, since this antibody plays a role in both of these areas. Keep in mind that this is just one part of the bigger picture, and other factors might be involved as well.
Symptoms of Low Levels
Symptoms of low levels of GAD-65 Antibody may not be easily noticeable as they could be subtle or non-specific. However, potential signs could include issues with nervous system function or irregularities in glucose metabolism.
Autoimmune Reactivity - Array 5 by Cyrex Laboratories
Serum
Measures IgG and IgA antibodies against different tissue antigens that are found from head to toe. These tissues are involved in more than 90 different autoimmune diseases. Detection of antibodies against these antigens at the early stage helps in the prevention and management of many autoimmune disorders since these predictive antibodies can be detected 3-19 years before the development of the clinical stage of an autoimmune disease. Developed and published by Aristo Vojdani, PhD, MSc, CLS, known as the father of functional immunology, in 2008, 2020, 2021, 2023, and 2024.
