Passing–Bablok comparison plot of the immunoturbidometric assay vs the LC-MS/MS method using the LVNEVTEFAK y5 peptide transition (575.5–595.6) for all samples ranging from the normoalbuminuric range up to the macroalbuminuric range.

Linear regression analysis (not shown) provided the following relationship: y = 0.99x + 23.16, R2 = 0.97.
