LP40011-6 Tissue transglutaminase Ab.IgA Tissue transglutaminase IgA detects tissue transglutaminase antibodies is an aid in the diagnosis of certain gluten sensitive enteropathies, such as celiac disease and dermatitis herpetiformis. Includes: Tissue Transglutaminase Ab (IgG), Tissue Transglutaminase Ab (IgA), Gliadin (Deamidated Peptide) Ab (IgG, IgA), Immunoglobulin A (IgA) ABN Requirement: No Specimen: Serum Volume: 5.0 mL Minimum Volume: 2.5 mL Container: Gel-barrier tube (SST, Tiger Top) Collection: Collect and label sample according to standard protocols. Aug 14, 2013 Clinical Significance: Tissue Transglutaminase Antibody IgG and IgA are useful in diagnosing gluten-sensitive enteropathies, such as Celiac gluten sensitive enteropathy in tTG-IgA negative patients with confirmed IgA deficiency. A negative Tissue Transglutaminase antibody test alone does not rule Tissue transglutaminase has been identified as the major autoantigen in celiac disease. IgA antibodies against tTG are highly disease specific serological Transglutaminase; Deamidated gliadin.

Transglutaminase Activity Assay Kit (ab204700) utilizes the deamidation reaction of the transglutaminase enzyme with a donor and acceptor substrate resulting in the formation of a hydroxamate product. The hydroxamate product reacts with the Stop Solution forming a purple complex that can be measured colorimetrically at 525 nm.

The most common and modern blood tests used to diagnose celiac disease are: Tissue transglutaminase IgA antibody level (commonly referred to as "tTG")

For individuals with moderately to strongly positive results, a diagnosis of celiac disease is likely and the patient should undergo biopsy to confirm the diagnosis.

TISSUE TRANSGLUTAMINASE AB, IGA Optimal Result: 0 - 4 U/mL. A tissue transglutaminase IgA (tTg-IgA) test is used to help doctors diagnose celiac disease. Celiac disease is an autoimmune disorder in which the immune system mistakenly thinks that gluten — a protein in wheat, barley, rye, and oats — is a foreign invader. The finding of tissue transglutaminase (tTG)-IgA antibodies is specific for celiac disease and possibly for dermatitis herpetiformis.

tTG for coeliac disease in prospective studies have been disappointing and false- positive All of them were on gluten containing diet. IgA anti-tTG antibody was the serological test used in our hospital; it was measured by a human recombinant enzyme- Antibody Tests · Tissue Transglutaminase (tTG) · Deamidated Gliadin Peptide ( DGP) · Endomysial Antibody (EMA) · Total Serum IgA. The numbers of patients with positive (+) and negative (−) serologies by the respective IgA and IgG antibody tests are shown. Serum IgA concentrations.Sera This assay is a porcine-based (ie, guinea pig), enzyme-linked immunosorbent assay (ELISA) that quantifies IgA antibodies to the tTG enzyme in human serum.

Presence of the tissue transglutaminase (tTG) IgA antibody is associated with glutensensitive enteropathies such as celiac disease and dermatitis herpetiformis. tTG IgA antibody concentrations greater than 40 U/mL usually correlate with results of duodenal biopsies consistent with a diagnosis of celiac disease.

The IgA blood test is used to determine how much immunoglobulin A is within the blood. IgA is one of the most common antibodies that is produced by the human body and consists of proteins that the immune system makes to help fight off invading viruses, bacteria, infections, or other toxins.
