Correction factors for oximetry parameters and bilirubin
Allowed
corrections The following corrections can be user-defined for the oximetry parameters and
bilirubin:

No No
FHHb No No
FHbF Yes Yes
ctBil Yes Yes
NOTE: In order to define the corrections accurately, the measurements of the
oximetry parameters and bilirubin on the ABL800 FLEX analyzers should be made
without any entered corrections. To avoid truncation errors from an enabled “Out
of range suppression” function it is important to disable the function.
