LOINC Code
| LOINC code | 84921-6 | ||
|---|---|---|---|
| name | Cells.chromosome region 7q31 deletion/Cells counted in Blood or Tissue by FISH | ||
| description | The percent of cells in blood or tissue containing the 7q31 deletion can be detected by FISH and used for the diagnosis of acute myeloid leukemia or myelodysplastic syndrome. This term is used to report the number of cells that have the 7q31 deletion out of total number of cells examined (e.g. 80 out of 100 cells, or 80%). Results are also typically reported in ISCN (International System for Human Cytogenetic Nomenclature) format [LOINC: 62356-1]. This term is based, but not limited in use to, the Vysis LSI D7S486/CEP 7 probe kit. To report percentage results for the CEP7 probe, used [LOINC: 84922-4]. | ||

| property | NFr = Number Fraction | ||
| 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 | ||
