LOINC Code 95552-6: 4p16.3 chromosome del FISH Doc (Bld/Tiss)

95552-6 is a LOINC code used to identify 4p16.3 chromosome del FISH Doc (Bld/Tiss) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component 4p16.3 chromosome deletion. It is commonly used with the system or sample type Bld/Tiss.

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 4p16.3 chromosome deletion. 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

  • 4p16.3 chromosome deletion in Blood or Tissue by FISH
  • 4p16.3 chromosome deletion
  • FISH studies are performed to detect a deletion on the short arm of chromosome 4 (4p16.3) in patients, primarily newborns, suspected of having Wolf-Hirschhorn syndrome (WHS). FISH signal pattern indicating a loss of 4p16.3 is consistent with a diagnosis of WHS. LOINC codes with a Scale of "Doc" can be used for the order and to represent the overall report and collection of results (clinical indication, method, overall findings, ISCN result, interpretation, etc.).
