Figure 1From: Paired measurement of urinary creatinine in neonates based on a Jaffe and an enzymatic IDMS-traceable assay Passing-Beblok (y = 0.28 + 0.95 ×, 95 % CI slope 0.93-0.98, 95% CI intercept 0.12-0.48) between enzymatic and Jaffe creatinine measurements (both mg/dL). (X-axis = creatinine in urine enzymatic, CreaU-enz, mg/dL; Y-axis = creatinine in urine Jaffe, Crea Jaffe U, mg/dL).Back to article page
