Change Reason
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.; Updated System from "Ser" since this test can be run on serum or plasma; Updated Answer list type from NORMATIVE to EXAMPLE because the Answers in the list (Positive, Negative) are only examples of possible answers and not an exclusive list
Order vs. Observation
Observation
