LOINC Code


LOINC code84916-6
nameCells.chromosome region 17p13.1 deletion/Cells counted in Blood or Tissue by FISH
descriptionDeletions at 17p13.1 involving the TP53 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 p53 (17p13.1) probe, which targets the TP53 gene and flanking regions.

componentCells.chromosome region 17p13.1 deletion/Cells counted
propertyNFr  =  Number Fraction
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemBld/Tiss
    Bld  =  Whole blood
    Tiss  =  Tissue, unspecified
scaleQn  =  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
