RBC SURVIVAL TEST
Note: The CAPTUS
®
4000e software follows the testing protocol outlined in the Mallinckrodt
RBC Survival kit that utilizes Sodium Chromate Cr51 injections.
This test is most frequently used in diagnosis of hemolytic anemia. The software
standardizes the 24-hour sample to 100% survival, and automatically decay-corrects each
subsequent sample. This permits the user to measure each sample as soon as it is collected.
For this reason, all sample volumes must be the same. Each sample must also have a
hematocrit (HCT) measurement. The subsequent samples are corrected for any differences
in hematocrit.
Select the Red Blood Cell Survival button or press Alt+R on Figure 10-1 Lab Tests Main
Screen. Figure 10-64 RBC Survival Test Main Screen will appear. The Patient Directory
box will be empty if there are currently no existing patients in the database. Each added
patient will appear in this box with their name and ID number along with the time and date of
the injection given to the patient. The Patient Status box will show the data status of the
patient if test has not yet been performed, or the latest test results.
