Varies (submit only one)
Submit only 1 of the following specimens: whole blood or bone marrow.
Refrigerated specimen must arrive within 5 days of collection, and ambient specimens must arrive within 3 days (72 hours) of collection.
PML/RARA (promyelocytic leukemia/retinoic acid receptor alpha) levels can only be compared reliably if tested in the same laboratory using the same procedure each time.
This assay will only detect PML/RARA RNA and will not detect RNA from the less common RARA fusion genes.
