| 0093199: T-Cell Clonality by Flow Cytometry Analysis of TCR V-Beta |
![[ image for: Time Sensitive]](icon_1.jpg){kind=icon} | Time Sensitive |
| Test Mnemonic: TCR V-BETA | |
|
Methodology: Flow Cytometry
Performed: Sun-Sat Reported: 2-4 days |
| Specimen Required: | |
|
Collect: One 6 mL green (sodium heparin).
Transport: 5 mL whole blood at 20-25°C. 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 (0093000) will be added, at an additional cost. Sample should be received within 24 hours of collection for optimal viability. In addition, please provide CBC, Wright's stained smear, clinical history, differential diagnosis, and any relevant pathology reports. Stability: Ambient: 48 hours; Refrigerated 48 hours; Frozen: Unacceptable |

Please refer to Statement A in the Compliance Statements section in the front of the Laboratory Test Directory. |
| 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). |
