Problem Description

for automatic case classification for COVID lab msgs, the NA code must result in Not a Case designation

Negative results are identified by using the code SARS-1 but providing the value NA.
For example, this means negative result:

                <observation moodCode="EVN" classCode="OBS">
                  <code code="SARS-1" codeSystem="1.3.182.5.21"/>
                  <value code="NA" xsi:type="CS"/>
                </observation>

No value is considered as NA
Only "CONF" and "PROB" values are considered as positive.

Proposed Change

Ensure that any lab msgs that come through with NA are automatically classified as not a case
