Flags
The RBC Irregular Flow Rate flag is triggered if the cell counting rate is erratic
because of a hydraulic disturbance in the RBC/PLT channel.
RBC flow rate is evaluated in terms of the cell counting rate:
Flow Uniformity =
Sum of the Squared Differences
9 x Mean Cell Counting Rate
The flag is triggered if this value is greater than 3.2.The RBC Rate Histogram
displays the arrival rate of cells in the RBC channel.

Results Flagged
RBC, HCT, MCV, MCH, MCHC, CHCM, CH, CHDW, RDW, HDW, PLT,
MPV, PDW
Corrective Action
1.
Check RBC reagents.
2.
Check RBC hydraulics.
3.
Check sheath delivery.
4.
Check the pressure and vacuum readings.
A partially clogged RBC/baso/retic sheath filter can produce a distinctive “ski
slope” effect on the RBC, Baso, and Retic flow rate histograms. Replace the
sheath filter.

Retic – Plt Interference Error (RTCint, CT)
Definition
The RTCint flag is triggered if the platelet threshold is set below scatter channel
5. If the flag is triggered, platelets may be counted in the gated mature RBC
population.
