Confirmation and Reflex Testing
Reflex tests are ordered when a particular test result indicates that additional testing should be performed. This is a list of Reflex Tests and their CPT4 codes. Our pathologists have reviewed these reflex tests and have confirmed that they follow accepted medical practice and are done in the best interest of the patient. The trigger which causes the additional test to be ordered is also indicated. Note: New Tests referred to a reference laboratory which include Reflex Testing will be added to this list when Applicable.
Confirmation tests are performed when a particular test result is positive. Additional testing is done to confirm the positive result or to report a titer following accepted medical practice. This is a list of tests and their billable CPT4 codes. Additional testing for cultures varies with the organisms identified.
