Corrective Action
Multiple occurrences of this flag, especially for consecutive samples, can indicate
a system problem. However, isolated instances of this flag are usually sample
related.
The following list of sample-related causes may not contain all conditions that
could cause this flag. There is no intention to associate the flag with specific
diagnoses.

1. Check delivery of the sheath reagent.
2. Check delivery of SHEATH/RINSE.
3. Check the RBC/Baso/Retic hydraulics.
4. Check the retic hydraulics.
5. Check retic gains.

Retic Slope Error (RTC-SE, SE)

Definition
The Retic Slope Error flag is triggered if the slope of the negative cell population
on the absorption axis is greater than 0.2 before the slope correction is applied.
The negative cell population should appear parallel to the y axis on the RETIC
Scatter Absorption cytogram. Signals will not gate properly if they exhibit a
backward or forward tilt.
