Comment
This term suggested the presence or absence of the rpoB gene indicates resistance to rifampin. However, the rpoB gene is present in all Mycobacterium species; it is the presence of certain variants in the rpoB gene that are associated with resistance to rifampin. Additionally, the term should have stated "Mycobacterium tuberculosis complex". The newer LOINC is modeled correctly.

Change Reason
Property changed from Acnc to fit the current LOINC model.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
