Identification of ACE inhibitor as a confounder in patient samples. Citrated plasma samples from 100 pulmonary clinic patients were analyzed for the presence of ACE inhibitor (ACEI) using the ZPHL/HHL ratio (A) and mAbs 1G12/9B9 binding ratio (B). Data are expressed as % of these parameters compared to those of control pooled plasma samples from healthy controls (green bars). Bar color scheme is as described in Fig. 1. Shown are mean values from 2 to 5 experiments (each made in triplicates); SD (not shown for clarity) was less than 10%. Concordance of these two parameters confirms the presence of ACEI in the samples
