Identification of severely IgA\u2010deficient (IgA SD) donors involved preliminary screening by the Ouchterlony double immunodiffusion assay followed by confirmatory testing at the required level of sensitivity for IgA and Ab at an external reference laboratory. Two in vitro particle gel immunoassays (ID\u2010PaGIA IgA deficiency test and anti\u2010IgA test) were also evaluated for their suitability in identifying IgA SD individuals and determining their Ab status.<\/jats:p><jats:p><jats:bold>STUDY DESIGN AND METHODS:<\/jats:bold> Samples from 198 donors and 36 patients, subjected to confirmatory testing for IgA SD and Ab over a 2\u2010year period, were also evaluated using the ID\u2010PaGIA kits.<\/jats:p><jats:p><jats:bold>RESULTS:<\/jats:bold> DiaMed test sensitivity and specificity for detection of IgA SD in donors was 98% whereas for Ab, test sensitivity was 91% at a specificity of 94%. In patients, sensitivity was 94% for IgA SD and 67% for Ab, both tests at a specificity of 100%.<\/jats:p><jats:p><jats:bold>CONCLUSIONS:<\/jats:bold> The ID\u2010PaGIA IgA deficiency test was a sensitive and specific tool for identifying IgA SD donors or patients. Sensitivity of the Ab test was high for donors but reduced for patients and of high specificity in both groups. Further studies with patients are needed to confirm this latter observation. Implementation of these tests would make it possible to supply appropriate products from IgA SD donors to prevent anaphylactic transfusion reactions in patients.<\/jats:p>","DOI":"10.1111\/j.1537-2995.2011.03513.x","type":"journal-article","created":{"date-parts":[[2012,1,9]],"date-time":"2012-01-09T19:15:00Z","timestamp":1326136500000},"page":"1792-1798","source":"Crossref","is-referenced-by-count":5,"title":["Evaluation of particle gel immunoassays for the detection of severe immunoglobulin A deficiency and anti\u2010human immunoglobulin\u2003A antibodies"],"prefix":"10.1111","volume":"52","author":[{"given":"Douglas S.","family":"Palmer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joan","family":"O'Toole","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Therese","family":"Montreuil","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vito","family":"Scalia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mindy","family":"Goldman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,1,9]]},"reference":[{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1423-0410.1984.tb01562.x"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1423-0410.1985.tb00151.x"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1537-2995.1991.31791368341.x"},{"key":"e_1_2_8_5_2","doi-asserted-by":"crossref","first-page":"226","DOI":"10.21307\/immunohematology-2019-454","article-title":"Review: IgA anaphylactic transfusion reactions.
