| description | Predicted phenotype for drug efficacy. A single marker interpretation value known to allow (responsive) or prevent (resistant) the drug to perform. Prior to the LOINC release 2.56 (June 2016), the answer list was updated per the recommendations of the Clinical Pharmacogenetics Implementation Consortium (CPIC). The previous answer list number was LL609-9, and three of the answer strings and LA codes are the same in the new list (ultrarapid metabolizer, intermediate metabolizer, and poor metabolizer). In the new answer list, the extensive metabolizer answer (LA10316-0) from LL609-9 has been replaced with two new answers (rapid metabolizer, normal metabolizer). LA10316-0 is still a valid LA code for the "extensive metabolizer" answer string. | ||||||||
