Troubleshooting Imprecise or Inaccurate Data
1.
Obtain a normal fresh whole blood sample. Select an empty QC file
and run a minimum of 10 Open mode runs into the file. Obtain a
printout of the file.
2.
Run a minimum of nine Closed mode runs into the same file. (For
the CELL-DYN 3000SL, aliquot a sample into three tubes and run
each tube three times.) Use the [REJECT SPECIMEN] key to
reject the Open mode runs and obtain a printout. This information
can be used to determine if the problem is mode or measurement
related.
3.
Compare the CVs of the precision data from a normal fresh whole
blood sample to the CVs of
Precision of the Hemogram Parameters (N = 20)
4.
Obtain printouts of related data as indicated in the following steps.
