IFCC model applied to 26 manufacturer/instrument means in CAP 2017 GH-5a survey (Sample GH5-01; HbA1c 46 mmol/mol, 6.4%) in the United States. The mean between-laboratory CV is on the horizontal axis; the mean manufacturer absolute bias (IFCC in mmol/mol; NGSP in %) is on the vertical axis. The black star represents the overall mean of all laboratories. The circles (laboratory instruments) and squares (POCT/ dry chemistry instruments) represent specific manufacturers with colors for analytical principles: green (immunoassays), red (ion exchange HPLC), yellow (boronate affinity), blue (capillary electrophoresis), pink (enzymatic assays).
