Passing–Bablok comparison plot for the macroalbuminuric range (>200 mg/L) of the LC-MS/MS method QTALVELVK y5 peptide transition (500.9–587.7) vs the LC-MS/MS method LVNEVTEFAK y5 peptide transition (575.5–595.6).

Linear regression analysis (not shown) provided the following relationship; y = 0.97x – 36.61, R2 = 0.99 (A) and the corresponding Bland–Altman plot over the macroalbuminuric region (B).
