| name | Cells.chromosome region 5q31 deletion/Cells counted in Bone marrow by FISH | ||
| description | The percent of cells in bone marrow containing the 5q31 deletion involving the EGR1 gene can be detected by FISH and used for the diagnosis of chronic lymphocytic leukemia (CLL), multiple myeloma as well as other forms of cancer. This term is used to report the number of cells that have the 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 EGR1 (5q31) probe, which targets the EGR1 gene and flanking regions. | ||

| component | Cells.chromosome region 5q31 deletion/Cells counted | ||
| 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 | Bone mar = Marrow (bone) | ||
| 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 | ||
