Teo et al reported equations for estimating urine protein excretion from analysis of a spot urine. The authors are from the National University of Singapore.
Parameters:
(1) urine protein in mg/dL
(2) urine creatinine in mg/dL
(3) urine albumin in mg/dL
urine protein to urine creatinine ratio = UPCR =
= (urine protein) / (urine creatinine)
urine albumin to urine creatinine ratio = UACR =
= (urine albumin) / (urine creatinine)
LOG10(24-hour urine protein excretion in grams) =
= (0.7150918 * LOG10(UPCR)) - 0.617019
24-hour urine protein excretion in grams =
= 10^((0.7150918 * LOG10(UPCR)) - 0.617019)
LOG10(24-hour urine albumin excretion in grams) =
= (0.8257142 * LOG10(UACR)) - 0.800153
24-hour urine albumin excretion in grams =
= 10^((0.8257142 * LOG10(UACR)) - 0.800153)
