NEW SENDOUT TEST
Hereditary Erythrocytosis Gene Panel, Next-Generation Sequencing
Order Code: NHEP
Fee Code: TBD (CPT 81404, 81405, 81479)
LOINC: 103735-7
Reference Lab: Mayo NHEP
Effective April 6, 2026, Michigan Medicine Laboratories Sendout Lab will go live with a new sendout test, Hereditary Erythrocytosis Gene Panel, Next-Generation Sequencing. Refer to Test Update 945 for collection instructions. This test is a reflex for Erythrocytosis Evaluation (TEST ID REVE2, also sent to Mayo Clinic Laboratories), but it can also be ordered independently. If the hemoglobin testing results from REVE2 do not explain the patient’s phenotype/hereditary erythrocytosis, the next-generation sequencing gene panel for hereditary erythrocytosis will be performed as a reflex at an additional charge. An individual interpretive report will be provided.
