Insulin is a hormone discharged by the pancreatic cells. The anti-insulin antibody test detects if your body has produced ample antibodies against insulin. It regulates the carbohydrate and fat metabolism in the body.
Insulin is essential for the cells of our body to metabolize glucose properly and function normally. The presence of GAD autoantibodies has been shown to be strong predictive marker for eventual onset of IDDM.
Glutamic acid decarboxylase is an enzyme that is found in high concentrations in the pancreas, it catalyzes the conversion of L-glutamic acid into g aminobutyrate and carbon dioxide via an irreversible reaction. Without sufficient insulin, cells starve and it would result in high blood sugar.
Auto- antibodies may develop in the body against the pancreatic cells, that produce it or against insulin itself. These autoantibodies reflect the destruction of the cells, the loss of the cell function and hence lack of insulin production, thus resulting in Type 1 diabetes. In contrast, type 2 diabetes primarily results from insulin resistance and does not involve autoimmune processes.

This anti insulin bodies test diagnosis the presence of IgG and IgM antibodies in the human body. It detects the risk for developing type 1 diabetes mellitus;and asseses between type 1, type 2 diabetes and gestational diabetes.
It observes prognosis of the clinical progression of type 1 diabetes and analyzes any allergic response to insulinTo check if insulin no longer seems to control the diabetesTo confirm insulin resistance when there is a difficulty in controlling their glucose levels with the standard treatment to determine if hypoglycemia is caused by insulin overuse.
Common symptoms associated are sudden weight loss, frequent urination, increased thirst and dehydration, slow healing of wounds and difficulty in maintaining glucose levels.
Preparatory instructions during specimen collection*:
Specimen type: Serum (Blood Sample)
Specimen collection procedure: Venipuncture - Collection of blood from a vein, usually from the arm.
|> 18 U/ml||Positive|
|12 - 18 U/ml||Equivocal|
|< 12 U/ml||Negative|
Inference: Normally, there are no antibodies against insulin in the blood. However if the body does have IgG and IgM antibodies against insulin, the body will treat the insulin as foreign. This may make insulin less effective, or not effective at all. If the test shows high levels of IgE antibody against insulin, then the body has developed an allergic response to the medication.
‘*A Reference range is a set of values which helps the healthcare professional to interpret a medical test. It may vary with age, gender, and other factors. Reference ranges may also vary between labs, in value & units depending on instruments used and method of establishment of reference ranges’
