LOINC Code
| LOINC code | 93804-3 | ||
|---|---|---|---|
| name | Chromosome 12 copy number/nucleus in Tissue by FISH | ||
| description | Aneusomy (varying number) of chromosome 12 is evaluated by using a DNA probe that marks the centromeric region of chromosome 12. Such a probe is also called CEP12. The ratio of the number of signals of the MDM2 gene, also on chromosome 12, to the chromosome 12 signal [LOINC: 93809-2] can indicate whether or not there is amplification of the MDM2 gene. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Chromosome 12 copy number/nucleus | ||
| property | EntNum = Entitic Number | ||
| 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 | Tiss = Tissue, unspecified | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
