LOINC Code


LOINC code74004-3
nameABCB1 gene mutations found [Identifier] in Blood or Tissue by Molecular genetics method Nominal
descriptionABCB1 (MDR1) gene mutation analysis is performed on patients who present with ineffectiveness or toxicity to certain drugs (protein MDR1 substrates). The patient's genotype is used to predict expression and activity of MDR1 enzymes (that regulate the transport of many drugs) and to determine appropriate treatment and drug dosage.
statusACTIVE

Fully-Specified Name

componentABCB1 gene targeted mutation analysis
propertyPrid  =  Presence or identity:  Prid stands for “Presence or identity”, is used for assays that detect whether or not an analyte of a particular kind is present, and if it is, to identify the specific analyte.
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemBld/Tiss
    Bld  =  Whole blood
    Tiss  =  Tissue, unspecified
scaleNom  =  Nominal:  Nominal or categorical responses that do not have a natural ordering. (e.g., names of bacteria, reported as answers, categories of appearance that do not have a natural ordering, such as, yellow, clear, bloody.
methodMolgen  =  Molecular Genetics:  General class of methods used to detect genetic attributes on a molecular basis including RFL, PCR and other methods.
