Notes
Docosahexaenoic acid (DHA) (mmol/l)
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)"
