Table 1.
Icterus interference cut‐off from Roche7 observed values and TCL (see abbreviation in text). For each analyte (column A), the tested range (column C) with the corresponding units (column B) is done. Roche's icterus interference cut‐off at 10% (column D) is compared to the value observed when there is 10% variation (column E). At least, I ict observed at TCL level (column F) is done. The values differ when TCL is not close to 10% (column G). Therefore, the interpretation is adapted to the analytical performance goals of the laboratory
