Baso Irregular Flow Rate (BIFR, BR)
Definition
The Baso Irregular Flow Rate flag is triggered when the cell counting rate is
erratic because of a hydraulic disturbance in the baso channel.
Baso 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 2.5.
The BASO Rate Histogram displays the arrival rate of cells in the baso channel.

Corrective Action
1.
Check baso reagents.
2.
Check baso hydraulics.
3.
Check sheath delivery.
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.
