#### Values

Code | Description | Note
--- | --- | ---
< | low off scale | Below absolute low-off instrument scale. This is statement depending on the instrument, logically does not imply LL or L (e.g., if the instrument is inadequate). If an off-scale value is also low or critically low one must also report L and LL respectively.
> | high off scale | Above absolute high-off instrument scale. This is statement depending on the instrument, logically does not imply LL or L (e.g., if the instrument is inadequate). If an off-scale value is also high or critically high one must also report H and HH respectively.
A | Abnormal | Abnormal (for nominal observations, all service types).
AA | Abnormal alert | Abnormal alert (for nominal observations and all service types).
B | better | Better (of severity or nominal observations).
D | decreased | Significant change down (quantitative observations, does not imply B or W).
H | High | Above high normal (for quantitative observations).
HH | High alert | Above upper alert threshold (for quantitative observations).
I | intermediate | Intermediate.
L | Low | Below low normal (for quantitative observations).
LL | Low alert | Below lower alert threshold (for quantitative observations).
MS | moderately susceptible | Moderately susceptible.
N | Normal | Normal (for all service types).
R | resistant | Resistant.
S | susceptible | Susceptible.
U | increased | Significant change up (quantitative observations, does not imply B or W).
VS | very susceptible | Very susceptible.
W | worse | Worse (of severity or nominal observations).
