Deamidated gliadinIgGnormal range The deamidated gliadin peptide IgA qualitative EIA test is a crucial diagnostic tool used to help identify celiac disease and other gluten-sensitive enteropathies. Understanding the normal range for this test is essential for accurate interpretation of results作者：S Rashtak·2008·被引用次数：174—The sensitivity, specificity, and accuracy were, respectively, 74%, 95%, and 86% for AGA II–IgA, 65%, 98%, and 84% for AGA II–IgG, and 75%, 94%, and 86% for AGA .... Gliadin, a protein found in wheat, barley, and rye, can trigger an autoimmune response in individuals with celiac disease, leading to the production of specific antibodies, including deamidated gliadin IgA.

What is Deamidated Gliadin Peptide IgA?

Gliadin is a component of gluten. When gliadin is "deamidated" (chemically altered), it becomes more immunogenic, meaning it's more likely to provoke an immune response in susceptible individuals. The deamidated gliadin peptide (DGP) test specifically looks for antibodies against these altered gliadin fragments.Deamidated Gliadin Peptide (DGP) Antibody, IgA - ARUP Lab The IgA designation refers to a specific type of antibody produced by the immune system. Elevated levels of deamidated gliadin IgA antibodies in the blood suggest an abnormal immune response to gluten.

Interpreting Deamidated Gliadin Peptide IgA Qualitative EIA Results

A qualitative EIA (Enzyme Immunoassay) test provides a result indicating whether the antibody is present or absent, or if it's below or above a certain threshold. The normal range for deamidated gliadin peptide IgA qualitative EIA can vary slightly between laboratories, but generally, a negative result indicates the absence or a very low level of these antibodies.

Several sources provide specific ranges:

* One common reference point is Negative: <20.0 U. In this scenario, a value of less than 20.0 Units (U) is considered normalIf theIgAresult is greater or equal to 1.0 mg/dL but lower than the age-specifiednormal range, then tTGIgA, tTG IgG,deamidated gliadin IgA, and deamidated .... A weak positive result might fall between 20.0-30.0 U, and a positive result would be greater than 30.0 U.

* Another frequently cited range is Negative: <15 U/mL. In this case, results below 15 U/mL are considered normal, while values of 15 U/mL or greater are positiveGliadin (Deamidated) Antibody (IgG, IgA) | Test Detail. This range is often associated with tests that also reflex to IgG if the total IgA is low.Deamidated Gliadin Antibody (Coeliac Disease Test)

* Some studies indicate a normal Gliadin (Deamidated) AB IGA is 4.These antibodies help detect an abnormal immune response to gluten and are particularly useful in situations where standard celiac tests may be less reliable.1.

* Additionally, a normal level of 25RU/mL has been reported for this specific antibody test.

It's important to note that these values are general guidelines.Deamidated gliadin peptide(DGP)IgAshould not be used for initial screening due to its low specificity and limited role in identifying undetected CD. The laboratory report itself will provide the specific normal range for interpretation.

The Role of Deamidated Gliadin Peptide IgA in Celiac Disease Diagnosis

The deamidated gliadin peptide IgA test is a valuable component of celiac disease screening. While tissue transglutaminase IgA (tTG-IgA) is often the primary screening test, deamidated gliadin antibodies can be particularly useful in certain situations. For instance, some individuals may have lower levels of total IgA, which can affect the reliability of tTG-IgA tests. In such cases, deamidated gliadin IgG may be considered alongside or instead of the IgA test.

Studies have evaluated the diagnostic performance of these antibodies.Reference Range: Gliadin (Deamidated) IgA:Negative: <15 U/mL Positive: 15 U/mL or greaterThe deamidated gliadin (DPG) IgA reflexes automatically to DPG IgG ... For example, one study reported a sensitivity of 74% and specificity of 95% for deamidated gliadin-IgA, and a sensitivity of 65% and specificity of 98% for deamidated gliadin-IgGReference Values.Negative: <20.0 U. Weak positive: 20.0-30.0 U. Positive: >30.0 U. Reference values apply to all ages.. Another research paper noted that anti-DGP-IgA and IgG assays were considered positive if ≥25 units, while TTG-IgA values >20 units were considered positive, highlighting the need to understand the specific assay and its associated values.2024年9月14日—The newest version of this test is called DGP (deamidated gliadin peptides) and is highly specific for coeliac disease.

It is important to remember that a negative IgA result in an untreated patient does not definitively rule out gluten-sensitive enteropathies, especially if IgG gliadin antibodies are present.Are You Confused About Your Celiac Disease Lab Results? - Furthermore, the deamidated gliadin peptide (DGP) IgA assay should not be used for initial screening alone due to its lower specificity compared to other markers.

In summary, interpreting deamidated gliadin peptide IgA qualitative EIA results requires careful consideration of the specific laboratory's provided ranges.
