Principles of Operation
Operational Messages and Data Flagging
Section 3
Patient, QC, Resistant RBC Mode Flagging (when WOC and NOC are equivalent)
Descriptor/Flag
Cause
Suggested Action
LRI
1) Interference in the lower threshold
region (2fL–3fL) > 25% of PLT count.
2) Too much interference between noise
and PLT population
3) Too much noise in the 0-low threshold
region
NOTE: LRI may be caused by:
Debris
Contaminated reagent
Microbubbles
Dirty Diluent/Sheath filter
Repeat the specimen. If the flag persists,
review a smear and verify the platelet count.
If the flag persists on subsequent samples,
check the platelet background count. If the
background count exceeds the specification,
troubleshoot accordingly.
URI
1) Interference in the upper threshold
region (15–35fL) > 25% of PLT peak
2) PLT aggregate count (PLT clumps)
> 15% of PLT count
URI may be cause by:
Microcytic RBCs
Schistocytes
Giant Platelets
Sickle Cells
Platelet Clumps
Review MCV, platelet histogram and
scatterplot.
If the scatterplot shows overlap in the RBC or
platelet populations or a population is present
above the platelet scatters, review a smear to
determine the cause and confirm the platelet
count.
LURI
Interference is present in both the upper
and lower regions of the PLT histogram.
Same actions as for LRI and URI
NO MPV
1) MPV < 3.5
2) PLT has an abnormal distribution
Repeat the specimen. If the MPV data is
suppressed, review the smear for abnormal
platelet morphology and platelet aggregates
and follow your laboratory’s review criteria.
Verify the platelet count.
