Type 1 diabetes is an inflammatory autoimmune disease of the pancreas, leading to destruction of the insulin-producing β-cells of pancreas, and resulting in a lack of insulin. [1] The lack of insulin leads to increased blood and urine glucose and produces classical symptoms of diabetes like polyuria, polydipsia and weight loss, etc. [2] Administration of insulin is essential for survival and it must be continued throughout the life, to lower the risk of long-term complications such as diabetic retinopathy, diabetic nephropathy, and cardiovascular disease.

Although of the total cases of diabetes, only 5% are of type 1 diabetes; it is the most common type of diabetes diagnosed in children and young adults. [3] Early treatment of type 1 diabetes is important in helping to prevent further deterioration of insulin-producing cells.

To help an early diagnosis of type 1 diabetes, United States Food and Drug Administration (USFDA) recently approved the first zinc transporter 8 autoantibody (ZnT8Ab) test that can help determine if a person has type 1 diabetes and not another type of diabetes. People with type 1 diabetes produce ZnT8Ab, while patients with type 2 and gestational diabetes do not. The ZnT8Ab enzyme-linked immunoassay easily detects the presence of the ZnT8Ab in the blood. [4]

Food and Drug Administration (FDA) approved the test based on data from a clinical study of 569 blood samples; 323 from patients with type 1 diabetes and 246 from patients diagnosed with other kinds of diabetes. The test was able to detect the ZnT8Ab in 65% of the samples from patients with diagnosed type 1 diabetes and gave a false positive result in less than 2% of the samples. FDA cautioned that a negative result from the test does not rule out a diagnosis of type 1 diabetes and that the test should not be used to monitor the stage of disease or a response to treatment. [5] When used meticulously with other tests and clinical information of the patient, the test may help some people with type 1 diabetes receive timely diagnosis and treatment.
