T-Cell Clonality by Flow Cytometry Analysis of TCR V-Beta : 0093199
[ image for: Time Sensitive]
Time Sensitive
  


Mnemonic: TCR V-BETA

Methodology: Flow Cytometry
Performed: Sun-Sat
Reported: 1-2 days
Specimen Required: Collect: Green (sodium heparin).

Specimen Preparation: Transport 5 mL whole blood.

Storage/Transport Temperature: Room temperature. Specimen should be received within 24 hours of collection for optimal viability.

Remarks: Previous leukemia/lymphoma phenotyping is required. If prior studies were not performed at ARUP, the outside flow cytometry report and histograms must accompany the specimen. If outside reports and histograms are not provided, a Neoplastic T-cell Evaluation test (ARUP test code 0093000) will be added, at an additional cost. In addition, please provide CBC, Wright's stained smear, clinical history, differential diagnosis, and any relevant pathology reports.

Stability (collection to initiation of testing): Ambient: 48 hours; Refrigerated 48 hours; Frozen: Unacceptable
Reference Interval:
By report
Interpretive Data:

See Compliance Statement A: www.aruplab.com/CS
Note: This assay is for further characterization of phenotypically abnormal T-cell populations identified by flow cytometry, and to determine whether there is evidence of monoclonality based on expression of T-cell antigen receptor beta chain variable regions (TCR V-Beta).
CPT Code(s): 88184 First marker; 88185 x23 Each additional marker; 88189 Interpretation for 16 or more markers.
