LOINC Code 74885-5: ERBB2 gene (HER2) duplication associated observations panel FISH (Tiss)

74885-5 is a LOINC code used to identify ERBB2 gene (HER2) duplication associated observations panel FISH (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 ERBB2 gene duplication associated observations panel. It is commonly used with the system or sample type 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 ERBB2 gene duplication associated observations panel. It is commonly used with the system or sample type 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: Order
  • Panel type: Panel
  • Method: FISH

What it does not mean

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

Key facts

ERBB2 gene (HER2) duplication associated observations panel - Tissue by FISH
ERBB2 gene duplication associated observations panel
This panel includes result codes commonly reported as part of a HER2 (ERBB2 gene) amplification in situ hybridization (e.g. FISH) study. The intention of this panel is to provide users with the associated LOINC codes. For LOINC mapping to the order and overall report of a HER2 amplification FISH study, use the ERBB2 gene duplication term [LOINC96893-3].
