LOINC Code 50554-5: Urinalysis microscopic panel Auto (U) [#/Vol]

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 Urinalysis microscopic panel. 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: Order
• Panel type: Panel
• Method: Automated count

What it does not mean

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

Key facts

• Urinalysis microscopic panel [#/volume] - Urine by Automated count
• Urinalysis microscopic panel
• Urinalysis microscopic panel [#/volume] in urine by automated count is the collection of automated terms that are per volume. These are created to ease the mapping of local codes for automated urinalysis machines to LOINC codes. The batteries include a set of tests reported one way- e.g. as concentrations of observed particles or cells, as number of particles or cell per microscopic field (we presume the units will say whether they are per HPF or per LPF- though crystals and cells are usually reported per HPF and casts per LPF), and one as categorical response, e.g. pos/neg or none, few many, loaded. Laboratories pick and choose how to report information that comes out of their automated instrument (which can provide numeric concentrations). So it is unlikely that any real UA panel will be of only one kind (e.g. NCNC, Naric , or Ord).
