B-Cell Acute Lymphocytic Leukemia (B-ALL) Minimum Residual Disease Detection by Flow Cytometry (COG Protocol)
Detect minimal residual disease in patients of all ages previously diagnosed with B-ALL.
Bone marrow. Whole blood: Green (Sodium Heparin) or Lavender (EDTA).
Transport 2 mL heparinized bone marrow (Min: 1.0 mL*) OR 3 mL whole blood (Min: 1mL*)
Room temperature. Also acceptable: Refrigerated. Specimen should be received within 24 hours of collection for optimal cell viability.
Clotted or hemolyzed specimens.
Provide specimen source, CBC, Wright stained smear (if available), clinical history, differential diagnosis.
Follow up: If previous leukemia/lymphoma phenotyping was performed at another lab, the outside flow cytometry report and histograms (if possible) should accompany the specimen.
Ambient: 48 hours; Refrigerated: 48 hours; Frozen: Unacceptable
Refer to report.
Analyte Specific Reagent (ASR)
This assay is a minimal residual disease assessment of B-ALL by flow cytometry.
Available Markers*: CD3, CD9, CD10, CD13, CD19, CD20, CD33, CD34, CD38, CD45, CD58, CD71, Syto 16
*Not all markers will be reported in all cases.
DAY 8 Peripheral Blood sample will have CD10, CD19, CD20, CD34, CD45, and Syto 16 run and reported. (6 markers total).
Day 29 Bone Marrow sample will have CD3, CD9, CD10, CD13, CD19, CD20, CD33, CD34, CD38, CD45, CD58, CD71, Syto 16 run and reported. (13 markers total).
The report will include a pathologist interpretation and a marker interpretation range corresponding to CPT codes of 2-8 markers, 9-15 markers interpreted. Charges apply per marker.
88184; 88185; each additional marker 88187 or 88188.
