Retic RBC Count Low (RTC-L, CL)

Definition
The Retic RBC Count Low flag is triggered if the number of cells analyzed is
less than 10,000.

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.
System Related
1. Insufficient sample
2. Incorrect open-tube sampler probe length
3. Replace the clot filter
4. Check the retic hydraulics.

Retic Saturation (RTCSAT, CS)

Definition
The Retic Saturation flag is triggered if the events counted in the Saturation Cell
area of the Retic Scatter Absorption cytogram are more than 10% of the gated
cell signals.
The Saturated Cells area of the Retic Scatter Absorption cytogram is located in
absorption channels 94 through 100.
