Unit Code 84159:
Methemoglobinemia Evaluation
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Diagnosing methemoglobinemia and sulfhemoglobinemia
Differentiating methemoglobinemia and sulfhemoglobinemia from
other causes of cyanosis (e.g., congenital heart disease)
Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Unit Code. Profile information lists tests performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

| 586 | Methemoglobinemia Interpretation | No | Yes |
| 83341 | Hemoglobin A2 and F | Yes | Yes |
| 81428 | Hemoglobin Electrophoresis, B | No | Yes |
| 80200 | Methemoglobin, B | Yes (order #81032) | Yes |
| 8272 | Sulfhemoglobin, B | Yes (order #81032) | Yes |
| 9323 | Methemoglobin M Ratios | No | Yes |
| 9325 | Hemoglobin Spectral Absorbance | No | Yes |
| 9322 | Methemoglobin Reductase, B | 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)
| Unit Code | Reporting Name | Available Separately | Always Performed |
| 9180 | Hemoglobin S, Scrn, B | Yes | No |
| 81510 | Agar Elec. Confirms | No | No |
| 9095 | Hemoglobin, Unstable, B | Yes | No |
| 81644 | IEF Confirms | No | No |
| 81509 | Globin Elec. Confirms | No | No |
| 8270 | Hemoglobin F, Red Cell Distrib, B | Yes | No |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
This is a consultative evaluation in which the case will be evaluated
at Mayo Medical Laboratories, the appropriate tests performed at
an additional charge, and the results interpreted.
