MEVP - Overview: Methemoglobinemia Evaluation

Test Catalog

Test Name

Test ID: MEVP    
Methemoglobinemia Evaluation

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis of methemoglobinemia and sulfhemoglobinemia


Differentiation of methemoglobinemia and sulfhemoglobinemia from other causes of cyanosis (eg, congenital heart disease)

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 IDReporting NameAvailable SeparatelyAlways Performed
MEVMethemoglobinemia InterpretationNoYes
A2FHemoglobin A2 and FNoYes
HBELHemoglobin Electrophoresis, BNoYes
METHMethemoglobin, BYes, (order MET)Yes
SULFSulfhemoglobin, BYes, (order MET)Yes
METRMethemoglobin Reductase, BYesYes

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests

Test IDReporting NameAvailable SeparatelyAlways Performed
HPFHHemoglobin F, Red Cell Distrib, BYesNo
SDEXHemoglobin S, Scrn, BYesNo
IEFIEF ConfirmsNoNo
HGBMOHGB Electrophoresis, MolecularNoNo
MASSHb Variant by Mass Spec, BNoNo
UNHBUnstable Hemoglobin, BNoNo

Testing Algorithm Delineates situations 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.
