The essential features of autoimmune diseases is that tissue injury is caused by immunologic reaction of the organism against its own tissues. These abnormal responses are usually triggered by bacterial or viral infections, smoking or endogenous abnormalities in the immune system. This autoimmune process can be antibody mediated or cell mediated and manifests in a large number of pathologic conditions.
Vitamins are essential constituents of human diet since they are synthesized inadequately or not at all in human body. Vitamin deficiencies affect all ages, the groups most susceptible to deficiencies are pregnant and lactating women, young children because of relatively high need, chronically ill patients and alcoholics. After gastric bypass surgery patients are at high risk of multiple vitamin deficiencies. Conversely, because of widespread use of nutrient supplements, nutrient toxicities are also gaining pathophysiological and clinical importance. Laboratory investigations play an important role in detecting subclinical deficiencies as well as probable toxicities in asymptomatic patients.
A complete vitamin profile test is a blood test that measures the levels of different vitamins in your body. It can help identify vitamin deficiencies or excesses, and assess your nutritional status.
What it measures
Why it’s important
This package measures blood glucose levels, including HbA1c levels. The HbA1c (hemoglobin A1c) test measures average blood sugar level over an extended period (8-12 weeks) and is a useful tool for both detecting and/or monitoring diabetes. Consistently elevated blood sugars can increase risk of heart disease, kidney damage and stroke thus monitoring and maintaining the right blood sugar levels is essential to prevent complications. It also includes a set of screenings commonly ordered at an annual health visit, including cholesterol and lipids, as well as kidney function tests to assess overall health.
Type 1 Diabetes mellitus (insulin-dependent diabetes mellitus, IDDM) is the result of a T-cell mediated destruction of the beta cells in genetically predisposed individuals. Autoantibodies to a variety of islet cell antigens appear during the course of autoimmune insulitis. Type 1 Diabetes is characterized by the presence of distinct circulating autoantibodies including autoantibodies to glutamic acid decarboxylase (GAD), protein tyrosine phosphatase (IA2), insulin, Zinc transport 8 (ZnT8) antibody and autoantibodies directed against cytoplasmic components of islet cells. Measurement of autoantibodies to GAD, IA2, insulin, ZnT8 and of cytoplasmic islet cell antigens (ICA) has been shown to be of significant value for the diagnosis and prediction of type 1 diabetes in first-degree relatives of diabetic patients. ZnT8 antibody complements GAD-65, IA-2, and insulin antibodies as it is positive in 3% to 4% of patients who are negative for GAD-65, IA-2, and insulin antibodies. Use of these 4 antibodies results in 93% to 98% sensitivity. One or several of these autoantibodies are found in most new onset type 1 diabetic patients. They can also be detected before the onset of the disease and characterize the so-called prediabetic period. These autoantibodies help to estimate the risk of an individual developing type 1 diabetes. Testing for all autoantibodies is highly recommended for risk assessment of type 1 diabetes.
