What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Cells.chromosome region 11q22.3 deletion/Cells counted. It is commonly used with the system or sample type Bld/Tiss.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both
  • Method: FISH

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

Cells.chromosome region 11q22.3 deletion/Cells counted in Blood or Tissue by FISH
Cells.chromosome region 11q22.3 deletion/Cells counted
Deletions at 11q22.3 involving the ATM 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 [LOINC62356-1]. This term is based, but not limited in use to, the Vysis LSI ATM (11q22.3) probe, which targets the ATM gene and flanking regions.
