Model of Ubukata et al for Estimating 24-Hour Urine Proteinuria From the Estimated 24-Hour Urine Creatinine Excretion

Parameters:

(1) body weight in kilograms

(2) height in cm

(3) age in years

(4) urine protein in mg/dL in a spot urine

(5) urine creatinine in mg/dL in a spot urine

urine protein to urine creatinine ratio =

= (urine protein) / (urine creatinine)

estimated 24-hour urinary creatinine excretion in grams =

= ((14.89 * (body weight)) + (16.14 * (height)) - (2.043 * (age)) - 2244.45) /1000

estimated 24-hour protein in g/day =

= (urine protein to urine creatinine ratio) * (estimated 24-hour urinary creatinine
