Factor Used for sample and control results.
Final result = (result * Factor) + Offset
The correlation factor is used to compensate for
differences in measuring methods of different
analyzers. By applying a factor, the final results
of the different analyzers can be directly com-
pared.
Offset The offset is used to compensate for differences
in measuring methods of different analyzers. By
adding the offset, the final results of the different
analyzers can be directly compared.
Valuation No Valuati on
Reference Range Use the limits defined as Low Limit and High
Limit.
Low Used On, Off Refers to Low Limit.
High Used On, Off Refers to High Limit.
Low Limit Results that are outside the limit are flagged.
High Limit Results that are outside the limit are flagged.
TRL Threshold value below which the results are no
longer displayed, instead it is indicated that the
value is smaller than the TRL value and the
<Test Rng flag is added.
Note that you can only change this value if TRL
Check is activated. (Utilities > Configuration >
System > TRL Check)
