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 Ethanol cutoff. It is commonly used with the system or sample type Urine.

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: Observation
  • Method: Confirm

What it does not mean

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

Key facts

  • Ethanol cutoff [Mass/volume] in Urine for Confirmatory method
  • Ethanol cutoff
  • Detection of ethanol levels greater than 10 ng/ml may indicate recent usage of an ethanol-containing product. Typical detection time in urine is up to 12 hours. Ethanol may also be produced in samples containing glucose and yeast due to fermentation occurring in samples after collection.
