Test ID: REVE    
Erythrocytosis Evaluation

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

Definitive, comprehensive, and economical evaluation of an individual with JAK2-negative erythrocytosis associated with lifelong sustained increased hemoglobin or hematocrit

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 at Mayo Clinic Laboratories, the appropriate tests performed at an additional charge, and the results interpreted.

 

This profile evaluates for hereditary (congenital) causes of erythrocytosis. Symptoms should be long-standing or familial in nature. All cases will be tested for p50 (if shipping control is received) and hemoglobin variants (cation exchange HPLC, capillary electrophoresis and mass spectrometry) with an interpretative report. Additional testing is guided in a reflexive manner, and may include molecular testing of the HBA1/HBA2, HBB, EPOR, VHL, EGLN1(PHD2), EPAS1(HIF2a), and BPGM genes, among others, as appropriate. See Erythrocytosis Evaluation Testing Algorithm in Special Instructions. An information sheet relaying clinical history, EPO levels, and JAK2 results allows more complete interpretation, if known.

 

REVB / Erythrocytosis Summary Interpretation, an additional consultative interpretation that summarizes all testing, will be provided after test completion to incorporate subsequent results into an overall evaluation if any of the following molecular tests are reflexed on the REVE / Erythrocytosis Evaluation:

-ATHAL / Alpha-Globin Gene Analysis

-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

-BPGMM / 2,3-Bisphosphoglycerate Mutase, Full Gene Sequencing Analysis

-HEMP / Hereditary Erythrocytosis Mutations
