| change reason | Clarified that the ordinal(pos/neg) test for urine and serum and are are not otherwise special (e.g multiple of the median) are usually used as pregnancy tests.; 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. | ||||
