LOINC display name : Cells.chromosome 7 monosomy/Cells counted FISH (Bld/Tiss);
LOINC long common name : Cells.chromosome 7 monosomy/Cells counted in Blood or Tissue by FISH;
LOINC short name : Cells.Chr Mono 7/Cells NFr Bld/T FISH;
LOINC description : The percent of cells in blood or tissue containing a single copy of chromosome 7 (monosomy
7) can be detected by FISH based on the number of chromosome 7 probe signals and used
for the diagnosis of acute myeloid leukemia or myelodysplastic syndrome. This term
is used to report the number of cells that have a chromosome 7 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(7q31)/CEP
7(7p11.1-q11.1) probe kit. To report percentage results for the 7q31 (D7S486) probe
deletion, used [LOINC: 84921-6].;
