At endoscopy, serum was collected from all of the patients, and 9 different coeliac antibody assays were performed, both as isolated assays and in combination. These included immunoglobulin A (IgA) anti\u2010tissue transglutaminase (TGA), and IgA plus IgG anti\u2010deamidated gliadin peptide (DGPAG). A diagnosis of CD was made if the biopsies showed Marsh grade 3 lesions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>Twenty\u2010four of 79 children had CD confirmed histologically. Only 39 of 79 were positive for Inova TGA, and 35 of 79 were positive for Inova DGPAG. Twenty\u2010four of 39 who were TGA positive and 24 of 35 who were DGPAG positive had confirmed CD on biopsy. There was good correlation between TGA and DGPAG\u2010positive predictive values. None of the modified gliadin tests produced false\u2010negative results, and neither did the TGA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>The Inova DGPAG and TGA assays have similar use in predicting CD in a selected paediatric population; however, in children who are positive for TGA when screened for CD, more than half have negative TGA serology when repeat testing is done at the time of biopsy. Those with persistent TGA positivity have only a 61.5% probability of having histologic CD, compared with 68.6% of those children positive for DGPAG.<\/jats:p><\/jats:sec>","DOI":"10.1097\/mpg.0b013e31828b382d","type":"journal-article","created":{"date-parts":[[2013,2,12]],"date-time":"2013-02-12T12:05:55Z","timestamp":1360670755000},"page":"43-48","source":"Crossref","is-referenced-by-count":7,"title":["Diagnostic Utility of Modified Gliadin Peptide Antibody Assays in New Zealand Children"],"prefix":"10.1002","volume":"57","author":[{"given":"Benjamin C.","family":"Hope","sequence":"first","affiliation":[{"name":"King's College Hospital Denmark Hill London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rohan","family":"Ameratunga","sequence":"additional","affiliation":[{"name":"Clinical Immunology Auckland Hospital and Labplus Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul M.","family":"Austin","sequence":"additional","affiliation":[{"name":"Labplus Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helen M.","family":"Evans","sequence":"additional","affiliation":[{"name":"Department of Paediatric Gastroenterology Starship Children's Hospital Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeannette","family":"MacFarlane","sequence":"additional","affiliation":[{"name":"Department of Pathology Auckland Hospital Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Mouat","sequence":"additional","affiliation":[{"name":"Department of Paediatric Gastroenterology Starship Children's Hospital Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon E.","family":"Chin","sequence":"additional","affiliation":[{"name":"Department of Paediatric Gastroenterology Starship Children's Hospital Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,7]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1067\/S0022-3476(03)00282-8"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2005.04.013"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2006.094045"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00431-008-0845-4"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2005.02.028"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/gut.35.6.776"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2007.01.003"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2005.02.012"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2006.02.010"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.2.5269.1727"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/00042737-200605000-00006"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/nm0698-713"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1093\/clinchem\/47.11.2023"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2006.05.004"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0b013e3181c992be"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0b013e318195dae3"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/0016-5085(92)91819-P"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.81.1.102"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2006.107946"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0b013e31817d80f4"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572-0241.2007.01360.x"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2010.09.006"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1097\/00042737-199803000-00013"},{"key":"e_1_2_8_25_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0b013e31821a23d0"},{"key":"e_1_2_8_26_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0b013e3182407c6b"},{"key":"e_1_2_8_27_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.molmed.2010.09.003"},{"key":"e_1_2_8_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2010.09.006"},{"key":"e_1_2_8_29_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0198-8859(03)00027-2"},{"key":"e_1_2_8_30_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.mpg.0000189337.08139.83"},{"key":"e_1_2_8_31_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1536-4801.2004.tb12143.x"},{"key":"e_1_2_8_32_1","doi-asserted-by":"crossref","unstructured":"ScottBB LosowskyMS.
