Notes

Coding 41 defines 5 special values:

-5 represents "indicates derived value or ratio cannot be computed (missing code I)"

-4 represents "indicates value not available (missing code A)"

-3 represents "indicates value was rejected by automatic sample and measurement quality control"

-2 represents "indicates a measurement cannot be quantified due to detected irregularity in sample - see tags"

-1 represents "indicates a measurement not defined (i.e. derived value or ratio cannot be given due to low concentration in original measure)"
