TEa % and Units
In the Cualia app, you have the ability to set TEa values, one in raw units and one in a percent. Additionally, you can specify the source of the TEa values, choosing from a list of common reputable sources such as RCPA and CLIA, or entering from your own sources.
To remove a TEa value from a test, select the X next to it.
When setting the value, you may check “Add TEa to Library” in order to make this TEa available in your standard library for all tests with the same analyte.
Test Systematic (SEa) and Random Error (REa) allowance %
The test’s SEa and REa percentages can be set from the slider. The two values will always add to 100%.
Total Allowable Error (TEa) is the maximum permissible error/difference between Actual (sample result) and Expected (true value). Actual and Expected results within TEa are said to be in Agreement.
TEas are established through a combination of clinical requirements, regulatory standards, biological variation and performance data from validation studies. The process involves several steps to ensure that the TEa is appropriate for the intended use of the test and meets necessary quality standards.
Generally, it is best to use TEas from authoritative bodies such as CLIA, RCPA and ISO who provide acceptable error rates for many analytes.
