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 |
|---|---|---|---|
| A2F | Hemoglobin A2 and F | Yes | Yes |
| HBEL | Hemoglobin Electrophoresis, B | No | 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 |
|---|---|---|---|
| HPFH | Hemoglobin F, Red Cell Distrib, B | Yes | No |
| UNHB | Hemoglobin, Unstable, B | Yes | No |
| SDEX | Hemoglobin S, Scrn, B | Yes | No |
| IEF | IEF Confirms | No | No |
| MASS | Hb Variant by Mass Spec, B | No | No |
| HGBMO | HGB Electrophoresis, Molecular | No | No |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Hemoglobin electrophoresis cascade will always include hemoglobin A(2) and F and hemoglobin electrophoresis.
Reflex testing-Hemoglobin electrophoresis reflex testing performed at additional charge, may include any or all of the following as indicated to identify rare hemoglobin variants present: hemoglobin S screen, unstable hemoglobin, IEF confirms, hemoglobin variant by mass spec, hemoglobin F red cell distribution, beta-globin gene, large del/dup, alpha-globin gene sequencing, and beta-globin gene sequencing.
Special Instructions and Forms Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test
