50554-5

LOINC code 50554-5 identifies "Urinalysis microscopic panel [#/volume] - Urine by Automated count". 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).

This code measures Urinalysis microscopic panel in Urine. It belongs to the PANEL.UA class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
