Test Name

Test ID: REVE    
Erythrocytosis Evaluation

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

Definitive evaluation of an individual with JAK2-negative erythrocytosis associated with lifelong sustained increased red blood cell mass, elevated red blood cell count, 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 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.
