3. Remove statistical outliers from the data by eliminating values outside
of ±3 SD.
NOTE:
Ensure that you include a significant number of results at the
extremes of the concentration ranges. If you do not, it could compromise the
quality of the correlation.
4. Perform a regression analysis.
Perform the analysis using a computer that can calculate the regression by the
Deming algorithm. This algorithm provides debiased slope and offset and is
the recommended method. A less acceptable alternative is to perform the
linear regression on a calculator or computer that does not use the Deming
algorithm.
The correction equation must be in the following form:
y = mx + b
where m is the slope and b is the offset
Use the results from the Rapidlab 1200 systems as the independent variable
(x). Use the results from the reference analyzer as the dependent variable (y).
NOTE:
You must perform the calculations as described above. The
calculation of a correction equation is the mathematical inverse of the
traditional correlation equation. Failure to calculate the regression as
described above produces an inaccurate correlation with the reference
analyzer.
5. Enter the slope and offset values.

Combining Results for an a-v Study Report
Use this procedure to combine the results from an arterial and a mixed-venous
blood sample to create an a-v study report. You can combine results only for
Rapidlab 1245 or 1265 systems. Arterial blood sample results can only be
combined with mixed-venous blood sample results and not venous blood sample
results.
