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 Crystals. 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

Crystals [#/area] in Urine sediment by Automated count
Crystals
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.
