New Urinalysis Platform: Sysmex UN-Series

Effective March 15, 2021, Clinical Pathology Laboratories (CPL) will be transitioning to a new urinalysis platform. The Sysmex UN-Series is an integrated urinalysis solution used for the in vitro analysis of human urine.  The series is designed to perform urine sediment testing by utilizing the Siemens CLINITEK Novus Automated Urine Chemistry Analyzer, UF-5000^TM Automated Urine Particle Analyzer, the UD-10TM Automated Urine Particle Digital Imaging Device, and Urinalysis Data Manager (UDM^TM). 

Operational improvements of this system include flow cytometry analysis of both formed and cellular elements to provide an additional screening tool for operators and a STAT/Manual Mode option that reduces the minimum required specimen volume from 7 mL to 4 mL.

Reflex criteria from urine chemistry to sediment analysis will include (additional charges will apply):

• Positive BLOOD
• APPEARANCE is anything except clear
• Positive LEUKOCYTE ESTERASE
• Positive NITRITE
• Positive PROTEIN

Patient final report changes going forward will include:

• NONE SEEN to be reported for hyaline casts and bacteria when no particles are present upon analysis
• Reporting units for crystals and casts to be removed from the report to streamline report interpretation for clinicians

Under most circumstances, clinically relevant crystal reporting in urines is performed through qualitative analysis and reported as such. This modification aligns testing at CPL with widely-accepted clinical industry standards. 

Unit code methodology statements will be updated accordingly in the test catalog to include relevant instrument descriptions.
