NOTES:
a.
pH = 7.4 ± 0.1. FHbF is adjusted with the pH sensitivity to a nominal
pH=7.4. For further details please refer to the Interference Tests section for
oximetry parameters.
b. Specifications for imprecision are derived from worst-case values found
during internal laboratory tests. 40 % relative is then added as a safety
factor.
