CYP3A4 gene c.-392A>G (*1B) [Presence] in Blood or Tissue by Molecular genetics method 74003-5
LOINC Code
| LOINC code | 74003-5 | ||
|---|---|---|---|
| name | CYP3A4 gene c.-392A>G (*1B) [Presence] in Blood or Tissue by Molecular genetics method | ||
| description | CYP3A4 gene mutation analysis for targeted variant CYP3A4*1B is performed to determine a patient's allellic genotype. The resulted genotype is used to predict overall drug metabolism phenotype (ultrarapid, extenisive, intermediate, or poor metabolizer). | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | CYP3A4 gene.c.-392A>G (*1B) | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Bld/Tiss Bld = Whole blood Tiss = Tissue, unspecified | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | Molgen = Molecular Genetics: General class of methods used to detect genetic attributes on a molecular basis including RFL, PCR and other methods. | ||
Additional Names | |||
| short name | CYP3A4 c.-392A>G (*1B) Bld/T Ql | ||
Basic Attributes | |||
| class | MOLPATH.PHARMG | ||
| type | 1 Laboratory | ||
| order vs. observation | Both | ||
Associated Observations | |||
LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations. | |||
History/Usage | |||
| first released | |||
| last updated | 2.67 | ||
| last change type | MIN - change to field other than name | ||
| change reason | Release 2.67: CLASS: Updated to MOLPATH.PHARMG, the more representative LOINC Class for this concept.; Previous Releases: 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. | ||
