CPT code:	81315

Specimen(s):

Bone Marrow Aspirate, Peripheral Blood

Collection Medium:

Pink top tube 6 mL (K2-EDTA)

Minimum:

5.0 mL Bone Marrow Aspirate or Peripheral Blood in EDTA anti-coagulated pink top tube

Rejection Criteria:

Specimens must be received within 72 hours of collection. Optimal results are achieved if specimen is received within 48 hours of collection.

Turn Around Time:

7–10 days upon receipt in laboratory

Test Limitations:

Samples must be refrigerated within one hour and must be received within 72 hours of collection. Optimal results are achieved if specimen is received within 48 hours of collection.

Methodology:

The PML-RAR (t(15:17)) RNA Quantitation assay uses multiplex reverse transcription in combination with droplet digital PCR technology. The assay can reliably detect 1 tumor cell in a background of 20,000 normal cells. The limit of quantitation is 0.01% NPM1/ABL1 ratio.

Instructions:

Testing requires dedicated collection tube.

Sample Processing:

Do Not Centrifuge.

Sample Storage:

Refrigerate.

Transport Instructions:

Place specimen into zip-lock type bag, seal bag.
Place packing list into outside pocket of bag.
