Test ID: HAEV1    
Hemolytic Anemia Evaluation, Blood

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

Evaluation of lifelong or inherited hemolytic anemias, including red cell membrane disorders, unstable or abnormal hemoglobin variants, and red cell enzyme disorders

 

This evaluation is not suitable for acquired causes of hemolysis.

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.

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 and appropriate tests performed, at an additional charge, and the results interpreted. If a peripheral blood smear is provided, the morphologic features will be incorporated into the interpretation.

 

RBC enzymes will always be performed. Capillary electrophoresis, cation exchange high-performance liquid chromatography (HPLC) and hemoglobin stability studies will always be performed. Reflex testing required to positively identify a hemoglobin abnormality may be added as the case requires. Osmotic fragility (OF) and eosin-5-maleimide (EMA) binding band 3 flow cytometry will be performed on all cases. A normal shipping control for OF is necessary to exclude false-positive results due to preanalytic artifact.

 

The protein and molecular test results will be released separately which may result in incomplete data until all testing has been finalized.

 

One or more of the following molecular tests may be reflexed on this test:

-ATHAL / Alpha-Globin Gene Analysis, Varies

-WASQR / Alpha-Globin Gene Sequencing, Blood

-WBSQR / Beta-Globin Gene Sequencing, Blood

-WBDDR / Beta-Globin Cluster Locus Deletion/Duplication, Blood

-WGSQR / Gamma-Globin Full Gene Sequencing, Varies

 

An additional comprehensive consultative interpretation that summarizes all results will be provided after all tests are completed to incorporate results into an overall evaluation.
