In this study, a negative urinalysis for protein excluded microalbuminuria in 87% and proteinuria in 78% of cases. &lt;i&gt;Conclusion:&lt;\/i&gt; Qualitative testing for protein by urinalysis has a high sensitivity and specificity for diagnosing or ruling out microalbuminuria. Trace proteinuria usually means microalbuminuria; negative proteinuria tends to rule it out.<\/jats:p>","DOI":"10.1159\/000074535","type":"journal-article","created":{"date-parts":[[2003,10,31]],"date-time":"2003-10-31T15:06:34Z","timestamp":1067612794000},"page":"438-441","source":"Crossref","is-referenced-by-count":14,"title":["The Significance of Trace Proteinuria"],"prefix":"10.1159","volume":"23","author":[{"given":"R.","family":"Sam","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.S.","family":"Shaykh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.A.","family":"Pegoraro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V.","family":"Khalili","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Hristea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.K.","family":"Singh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.A.L.","family":"Arruda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Dunea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2003,11,21]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0272-6386(03)00648-6"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/S0272-6386(03)00742-X"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1159\/000065220"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-8981(00)00181-9"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1001\/jama.235.12.1259"}],"container-title":["American Journal of Nephrology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/74535","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/74535","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:53:39Z","timestamp":1745466819000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000074535"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003]]},"references-count":5,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2003,12,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000074535","archive":["Portico"],"relation":{},"ISSN":["0250-8095","1421-9670"],"issn-type":[{"value":"0250-8095","type":"print"},{"value":"1421-9670","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003]]}}}
