Reference Intervals
Verify institutional intervals, no universal ranges in this reference.
Clinical and Laboratory Significance
Patterns suggest differential branches, morphology and persistence guide correlation.
Differential Considerations
Reactive vs concerning patterns, hedged language; confirmatory testing clinician-directed.
Comparison Tables
Classification Frameworks
Apply to confirmed neoplasms, not inferred from count alone.
Laboratory Notes
- Smear verification when automated flag present.
