RED BLOOD CELL SURVIVAL
This protocol is used to count samples taken as part of a procedure to measure Red Cell
Survival time. The protocol is set up so that samples are counted as they are withdrawn. The
CAPTUS
®
600 decay corrects the counts to the date and time the measurements are made.
The steps in using the RBC Survival protocol can be summarized as follows:
1. Inject patient with tagged RBC suspension.
2. At approximately 24 hours post injection, withdraw a blood sample, determine the
hematocrit, and count the sample in the Well. Save the results in the CAPTUS
®
600.
This value will be used as 100%.
3. Every two or three days repeat step 2. Do this for a minimum of 30 days or until the
50% remaining level is reached.
4. Print results.
From the Main Blood Tests Screen (
Figure 16-1), press 3 to select RBC SURVIVAL (Cr51).
