2. Figure 1
Scatter plots of urinary albumin, creatinine, and albumin-creatinine ratio (ACR) fresh and after storage. Axes are log-scale; the solid line indicates the line of perfect concordance (line of unity; n = 746). Limit of sensitivity for albumin was <1 mg/L for the Beckmann Array (fresh samples) and <2 mg/L for the Dade Behring Prospect Analyser (after storage).
