Testing Algorithm
When multiple specimen types are required to perform a panel of tests, the laboratory will perform the tests for which the appropriate specimen type was received and the laboratory will cancel those for which the appropriate specimen was not received. Be advised that this may change the degree of interpretation received with the report.
