A well-known and elaborated test method is required for properly assessing a test result.
In each accredited laboratory the documentation of the test method shall include at least:
detailed description of the test steps
instruments used and their settings
chemicals
tools used
methodology for evaluating the results
At least the following parameters depend on the chosen test method:
selectivity
linearity
sensitivity
detection limit
robustness
rigidity
accuracy
precision
Most of the parameters are necessary only for the internal lab operation.
The test method and the uncertainty associated with the test are of great significance for the customer.
Functionalities of the application (Imperium LIMS) related to the testing method:
independent testing methods can be defined
multiple testing methods can be assigned for a single test
no new test has to be defined for if you want to measure with another testing method
testing method can be assigned to controls
testing method can be selected at manual result entry
testing method can be defined for instrument
testing method and uncertainty can be displayed on the report
reference ranges depends on the selected testing method
