LOINC Code
| LOINC code | 24475-6 | ||
|---|---|---|---|
| name | F2 gene c.20210G>A [Genotype] in Blood or Tissue by Molecular genetics method Nominal | ||
| description | Factor II (Prothrombin) 20210G>A assays allow for the detection and genotyping of a single point mutation (G to A at position 20210) of the Factor II (F2) gene from DNA isolated typically from whole blood. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | F2 gene.c.20210G>A | ||
| property | Geno = Genotype | ||
| 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 | Nom = 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. | ||
| 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 | F2 c.20210G>A Geno Bld/T | ||
Basic Attributes | |||
| class | MOLPATH.MUT | ||
| type | 1 Laboratory | ||

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. | |||

| last change type | MIN - change to field other than name | ||
| change reason | Release 2.67: SCALE_TYP: Updated Scale from Ord to Nom based on the current LOINC naming model for concepts used to report the patient's genotype for a specific variant; PROPERTY: Updated Property from PrThr to Geno based on the current LOINC naming model for concepts used to report the patient's genotype for a specific variant; Previous Releases: Changed 'p' to 'c' in Component since this variant is described at the coding level (vs. protein level). Edited to term to harmonize with current recommended HGVS nomenclature.; Converted the answers in the description to an answer list.; 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. Updated Answer list to reflect that this term should be used to report the presence or absence of a single point mutation. This change was approved by the Laboratory LOINC Committee in December 2018. | ||
