9. When it is done counting the plasma sample, the system will display the "Verified Test Complete"
window, asking if you want to permanently save the data. In the lower left corner of the screen you
can see the calculations and results for the volumes and radioactive hematocrit percent number. To
accept the numbers that were taken, click <Yes> to save the data. If you wish to recount any of the
items, click <No>.

Cr-51 Blood Volume
(See Figure 9-3.)
To perform a Cr-51 blood volume test, prepare all your samples and label them according to the
manufacturer's kit instructions. When you are ready to count, you must first enter a patient into the
patient database and choose the Cr-51 blood volume test for that patient. If the patient is already in the
system, add a new test of the Cr-51 blood volume as a new procedure for this patient.
A one-time set up for the Cr-51 test would be to go to the procedure window and enter the count time
that you will use for each of the items into the procedure definition. Once this time is set and you save it,
all Cr-51 blood volume tests will use this counting time, unless adjusted.
1. At the Cr-51 blood volume counting page, verify that the patient Name and patient's ID# at the top of
the screen are correct.
2.
Click
on
<Preferences>
and
enter
the
patient
hematocrit
number
as
a
percentage.
Also
enter
the
Red
Blood Cell (RBC) suspension hematocrit as a percentage. If needed, adjust the counting time in this
window and then press <OK> to proceed.
3. Place the vial that will be used for counting background into the well counter and click on
<Background>. The system will now count for background. When counting is completed, the counts
and counts per minute will be displayed.
4. Remove the background vial from the well and insert the vial with the blood standard into the well
counter. Click on <Blood Standard> count the standard. When counting is completed, the counts and
counts per minute will be displayed.
5. Remove the blood standard vial from the well counter and insert the plasma standard vial into the
well
counter.
Click
<Plasma
Standard>
to
count
the
plasma
standard.
When
counting
is
completed,
the counts and counts per minute for the plasma standard will be displayed.
6. Remove the plasma standard vial from the well counter and put the blood sample vial into the well
counter. Click on <Blood Sample> to count the blood sample. When counting is completed, the
counts and counts per minute for the blood sample will be displayed.
7. Remove the blood sample vial from the well counter and place the plasma sample vial into the well
