RBC Flags
RBC
HGB — displayed next to RBC and HGB results (RBC and HGB are
always displayed together)
Cause: The relationship of the RBC and the HGB data do not meet
expected criteria.
Action:
Repeat the sample. If the flag remains, verify the RBC and
HGB results.
PLT Flags
LRI (Lower Region Interference) — displayed next to the MPV result
Cause: Interference in the lower threshold region (1–3 fL) of the PLT
histogram is greater than a predetermined limit. This is
generally non-biologic interference. The flag may be caused
by:
Debris (dirty aperture)
Contaminated reagent
Electronic noise
Microbubbles
Action:
troubleshoot as directed in the
within limits, repeat the specimen. If the flag persists, review a
stained smear to determine the cause of the interference and
confirm the PLT count.
URI (Upper Region Interference) — displayed next to the MPV result
Cause: Interference in the upper threshold region (15–35 fL) is greater
than a predetermined limit. This is generally biologic
interference. The flag may be caused by:
Microcytic RBCs
Schistocytes
Giant Platelets
Sickle Cells
Platelet Clumps
NOTE: A "bumpy" platelet histogram may indicate the
presence of platelet clumps.
