We identified alternative indices most correlated with 24-hour uric acid clearance (Cua 24\u2009h) and 24-hour Eua (Eua 24\u2009h) using data from the reference interval of urinary clearance and excretion of urate study.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>The subjects were indoor workers aged 20\u201365\u2009years who met the Clinical and Laboratory Standards Institute Guidelines C28-A3c. Alternative indices using spot urine were urine uric acid creatinine ratio, Cua\u2014creatinine clearance ratio (Cua\/Ccr), Eua\u2014CCr ratio (Eua\/Ccr), estimated Cua (eCua), and estimated Eua (eEua). eCua and eEua are the values obtained by multiplying Cua\/Ccr and Eua\/Ccr with the estimated glomerular filtration rate.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The final number of subjects analysed was 739.

Compared with Cua 60\u2009min and Eua 60\u2009min obtained from 60-min urine collection, eCua and eEua showed lower root means squared error, lower bias, and significantly higher accuracy of within
