biodex ATOMLAB 950 - Wipe Test Procedures

6. WIPE TEST
6-1 WIPE TEST
The Wipe Test is used to determine the DPM of swipes taken in the designated areas of a department
using the optional well counter Model #187-246. A total of 10 swipes may be identified and counted for
each area. When wipe counting is completed, a report of the Wipe Test results can be printed out with
each test identified by the area and wipe with results shown. The screen displays all wipes and stores the
results for each wipe until that wipe is recounted.
NOTE: In Wipe Test and Bioassay mode, the activity shown is NET activity. This means that the background count
is subtracted from the count before the activity is calculated. For all other modes, counts shown are the actual counts
detected and are not netted for background.
Define Wipe Areas
The Define Wipe Areas feature is used to define new areas or change information about existing areas. At
this screen, you can define individual wipe areas in the same manner as used for selecting, adding,
editing or deleting patients and isotopes.
NOTE: You must use the Isotope Editing screen to make isotopes available for use in Wipe Testing, and the Isotope
Efficiencies screen to enter the Detector Efficiency for each isotope. Refer to chapter 3 for details.
