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 Flow time. 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: Uroflowmetry

What it does not mean

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

Key facts

  • Flow time by Uroflowmetry
  • Flow time
  • The urine flow time is the duration of actual urination during the test. In contrast, the voiding time is the time from when the examiner tells the patient to start voiding until the patient is finished voiding, which may include an initial period of delay during which the patient is unable to urinate.
