NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.


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.
