Collection Instructions

Specimen:Blood or bone marrow. RNA.
Optimal Volume:10 mL blood; 3 mL bone marrow
Minimum\Peds Volume:5 mL blood; 1 mL bone marrow; 25 uL RNA at a concentration of 20 ng/uL.
Container:Yellow (ACD, Solution A) tube available from laboratory
Alternate Containers: Purple (EDTA)
Collection Instructions:
  • Blood: Collect in yellow ACD (Solution A) tube.
  • Bone marrow aspirate: Aspirate ACD (or EDTA) solution into syringe from open ACD (or EDTA) tube; collect 3 mL bone marrow into syringe.

Note: The use of an anticoagulant other than ACD (or EDTA) may interfere with the assay.  
Causes for Rejection:Blood or bone marrow specimen received more than 72 hours from the date of collection; incorrect volume or tube type; clotted or frozen specimens; RNA not received on dry ice. RNA extracted at non-CLIA certified (or equivalent) lab.
Shared samples will not be accepted unless sent to Molecular first. Contamination will occur on automated hematology analyzers.
