Explore the often overlooked preanalytical factors that can impact urinalysis accuracy, from collection and transport to storage, preservation, and handling. This session reviews common causes of false-positive and false-negative results, current CLSI, EFLM, and ASM best practices, and practical strategies to preserve specimen integrity. Discover how optimizations in the preanalytical phase can help you and your team work toward improving diagnostic confidence, reducing recollections, and supporting better patient outcomes.
Learnings and resources inside include:
- Time-to-analysis and preservation rules drawn from current guidance
- A troubleshooting reference for false-positive and false-negative causes across routine dipstick testing
- Contaminants and storage artifacts that can be mistaken for cellular findings
- Where specimen-to-additive ratio and mixing affect results, including with flow cytometry
