When looking at the HQMF file for measure CMS 52 v2 there is a section that corresponds to the logic:

Occurrence B of Laboratory Test, Result: CD4+ Count (result >= 500 per mm3)

In this section there is a "value" element that uses the unit "/mm3" when checking against the CD4+ Count result:

<value xsi:type="IVL_PQ">
<low value="500" unit="/mm3" inclusive="true"/>
</value>

However, when looking at the QRDA Cat 1 files produced by Cypress 2.4 for the patients HIV_Peds A and HIV_Peds B, it looks like they both have a CD4+ Count laboratory test result, but the unit used is "mm3" instead of "/mm3".

<value xsi:type="PQ" value="150" unit="mm3"/>

What unit is supposed to be used for CD4+ Count laboratory test results in the QRDA Cat 1 files?
