Please note that the reference ranges were established using the Jaffe method and we do not have the appropriate reference ranges for the enzymatic method. For checking renal function we recommend using cystatin C. < 3 years: no reference range available 3 years: 10.9 - 21.4 mg/kg BW x 24h [0.096 - 0.189 mmol/kg BWx24h] 4 - 5 years: 12.0 - 24.2 mg/kg BW x 24h [0.106 - 0.214 mmol/kg BWx24h] 6 - 8 years: 15.2 - 25.6 mg/kg BW x 24h [0.134 - 0.226 mmol/kg BWx24h] 9 - 13 years: 11.3 - 27.7 mg/kg BW x 24h [0.100 - 0.245 mmol/kg BWx24h] 14 - 18 years: 13.2 - 33.2 mg/kg BW x 24h [0.117 - 0.294 mmol/kg BWx24h] BW = body weight
