Chromosome 3 copy number/nucleus in Blood or Tissue by FISH 78238-3
LOINC Code
| LOINC code | 78238-3 | ||
|---|---|---|---|
| name | Chromosome 3 copy number/nucleus in Blood or Tissue by FISH | ||
| description | This term was created for, but is not limited in use to, the CEP 3 SpectrumOrange DNA Probe Kit, which detects sequences in the centromere region of chromosome 3 in order to identify chromosome 3 trisomy. This test is used as an adjunct to routine diagnostic cytogenetic testing involving chromosome 3. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Chromosome 3 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 | Bld/Tiss Bld = Whole blood 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 | ||
