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 Bacteria. It is commonly used with the system or sample type Urine sed.

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: Automated count

What it does not mean

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

Key facts

  • Bacteria [#/area] in Urine sediment by Automated count
  • Bacteria
  • Automated counters measure the number concentration directly and calculate values for the per HPF (or per LPF) when the laboratory chooses them. These analyzers generate the # per HPF or per LPF (as the particle requires) assuming a spun urine based on relationships between the volume of spun and unspun urine.
