Prediagnostic hypoalbuminemia occurs before PLA2R-AB elevation in a minority of cases. Representative MN cases showing prediagnostic hypoalbuminemia before seropositive PLA2R-AB. The left y axis represents the scale of the PLA2R-AB levels and the values are plotted in blue. The blue, horizontal dotted line is the cut-off for determining PLA2R-AB seropositivity. The right y axis denotes the serum albumin levels, and the cut-off value for determining hypoalbuminemia is shown by the black dotted line. (A) In patient 1, prediagnostic hypoalbuminemia occurs before elevated PLA2R-AB. (B) In patient 2, hypoalbuminemia occurs before elevated PLA2R-AB. (C) In patient 3, hypoalbuminemia occurs before elevated PLA2R-AB. (D) In patient 4, hypoalbuminemia occurs before elevated PLA2R-AB.
