PML/RARA t(15;17), Quantitative, Real Time‑PCR
Also known as: Translocation (15;17), PML/RARA, Quantitative RT-PCR, AML(M3), APL
Use
This assay detects the short form (bcr3), long form (bcr1) and the variant exon 6 (bcr2) PML‑RARA transcripts associated with the t(15;17) chromosomal translocation. PML‑RARA transcript levels are expressed as normalized copy number (NCN) of PML‑RARA using ABL1 as internal control. Optimal for diagnosis and monitoring of acute promyelocytic leukemia (APL).
Special Instructions

Include date and time of draw and sample type on tube. Insurance authorization is required prior to draw for outpatients; inpatients are acceptable to send without prior authorization.
