Yamamoto et al reported an equation for estimating the urine albumin to creatinine ratio (ACR) from the urine total protein to creatinine ratio.
Parameters:
(1) urine total protein to creatnine ratio (TPCR) in mg/g
LN(estimated urine albumin to creatinine ratio in mg/g) = X =
= (1.32 * (LN(TPCR))) - 2.64
estimated urine albumin to creatinine ratio in mg/g =
= EXP(X)
