LOINC Code 80738-8: TPMT gene targeted mutation analysis Sequencing Nom (Bld/Tiss)

80738-8 is a LOINC code used to identify TPMT gene targeted mutation analysis Sequencing Nom (Bld/Tiss) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component TPMT gene targeted mutation analysis. It is commonly used with the system or sample type Bld/Tiss.
