T-Cell Clonality Assessment by Restriction Fragment-Southern Blot Hybridization, Fluid : 0055596

Mnemonic: TCRFSBHF

Methodology: Restriction Fragment Southern Blot Hybridization
Performed: DNA isolation: Sun-Sat; Assay: Varies
Reported: 7-14 days
Specimen Required: Collect: Lavender (EDTA) or bone marrow (EDTA).

Specimen Preparation: Transport 5 mL whole blood (Min: 1 mL) OR 3 mL bone marrow (Min: 1 mL).

Storage/Transport Temperature: Refrigerated.

Unacceptable Conditions: Specimens collected in anticoagulants other than EDTA. Frozen specimens. Clotted or grossly hemolyzed specimens.

Stability (collection to initiation of testing): Ambient: 24 hours; Refrigerated: 5 days; Frozen: Unacceptable
Interpretive Data: By report

Refer to Statement B under Testing Information at http://www.aruplab.com.
Note: A positive result indicates the presence of monoclonal T-cell population within the sample.  A negative result does not entirely exclude the presence of a T-cell receptor gene rearrangement (or monoclonal T-cell population) in the sample.
CPT Code(s): 83891 Isolation; 83892 x3 Digestion; 83894 Gel Electrophoresis; 83897 Southern transfer; 83896 Nucleic acid probe; 83912 Interpretation and report - Additional CPT code modifiers may be required for procedures performed to test for oncologic or inherited disorders.
