The health consequences of erroneous patient results are major, since in a worst case scenario, a patient s tacrolimus dosing could be altered, resulting in potential organ failure and rejection (due to too low or no tacrolimus being administered) or toxicity (due to too much tacrolimus being administered). Siemens internal investigation of the Dimension TAC assay showed the worst case imprecision with patient samples at the low end of the Analytical Measurement Range (AMR). A patient sample at 2.0 ng/mL (2.6 nmol/L) recovered as 0.0 ng/mL (0.0 nmol/L) (100% negative bias), another patient sample at 2.1 ng/mL (2.7 nmol/L) recovered at 4.3 ng/mL (5.6 nmol/L)  (103% positive bias).",
