the
<Preferences>
button
and
then
enter
a
total
urine
volume
for
the
patient
that
you
are
testing. Once you have entered the total volume, click <OK>. You can now proceed with counting.
NOTE: You can change the sample volume, correction factor and count time for this study in the parameters
window.
NOTE: If you use a different standard volume or concentration, you must change the correction factor.
4. Click on the background button and the system will proceed to count lab background. When it is
done counting, the number of counts and the counts per minute will both be displayed.
5. Remove the background vial and insert the Co-57 standard into the well.
6. Click on the highlighted <Co-57> standard button. The system will now count the Co-57 standard.
When counting is finished, the total counts and the counts per minute will be displayed. The
<Sample> button should now be displayed.
7. Remove the Co-57 standard from the well and place the urine sample into the well.
8. Click on <Sample> to begin counting the urine sample. When counting is finished, the total counts
and counts per minute will be displayed.
9. When the system has completed the count, a window will be displayed asking to verify that the test
is complete. To save the results, click <Yes>. If you do not wish to Save, click <No> and you can
then proceed to recount any one of the three items counted.
NOTE: If an error was made in the total urine volume, do not click <Save>. You can go back and click on
<Preferences> to correct the error as long as you have not saved.
10. Once you have finished with any recounts for this patient, select <Save> to display the "Verify Test
Complete" screen. If the numbers are satisfactory, click <Yes> to save the results.

NOTE: The Bracco and Mallinckrodt kits use the same procedure. You can modify the sample volumes, but
then you must correct and enter the appropriate sample volume in milliliters in the Preferences window.
Schilling Test for the Simplified Mallinckrodt Procedure
(See Figure 8-3.)
This is the same as the Mallinckrodt and Bracco procedures except that you cannot enter a sample
volume in the Preferences window. For this test, you must use a 4ml volume in order for the system to
calculate correctly.
Schilling Dicopac
(See Figures 8-4 and 8-5.)
The Dicopac Schillings procedure is programmed to use the Mediphysics/Amersham Dicopac Schilling
Test Kit. The counting procedures and formulas for calculations are all from the manufacturer's Dicopac
Kit instructions.
