change reasonThis test is commonly performed on cells found in saliva and buccal swabs as well as blood specimens. Changed specimen from 'Bld' to 'Bld/Tiss' to represent both specimen types.; 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.
