Optimization of 25% Sulfosalicylic Acid Protein-to-Creatinine Ratio for Screening of Low-Grade Proteinuria

Table 5

Patient data for the calculation of performance characteristics of the 25% sulfosalicylic acid protein-to-creatinine ratio (SSA PCR) versus albumin-to-creatinine ratio (ACR).

	Diseased (ACR ≥30 mg/g)	Nondiseased (ACR <30 mg/g)
25% SSA PCR ≥150 mg/g	25	4
25% SSA PCR <150 mg/g	2	9

25% SSA PCR: 25% sulfosalicylic acid protein-to-creatinine ratio; ACR: albumin-to-creatinine ratio.
