Profile Information
A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| F_9 | Coag Factor IX Assay, P | Yes | Yes |
Reflex Tests
Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| IBETH | Bethesda Units | No | No |
| F9_IS | Factor IX Inhib Scrn | No | No |
| CCCR | Special Coagulation Interpretation | No | No |
Testing Algorithm
Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Testing begins with coagulation factor IX activity assay with dilutions to evaluate assay inhibition; if the factor IX activity assay is decreased, an inhibitor will be performed to look for specific factor IX inhibition. If specific inhibition is apparent, it will be titered.
