T-cell Receptor Gamma Gene Rearrangement

Molecular

81342

This test provides detection of clonal T-cell receptor gamma (TCRG) gene rearrangements by PCR of variable and joining regions. T-Cell Receptor Beta Gene Rearrangement is offered separately and may be added to this gamma gene test.

• Bone marrow aspirate: 1-2 mL in EDTA tube (purple top) preferred; ACD (yellow top) acceptable
• Peripheral blood: 5-10 mL in EDTA tube (purple top) preferred; ACD (yellow top) acceptable
• Fresh Tissue: Minimum of 250 mg tissue in RPMI transport media
• Formalin-Fixed Paraffin-Embedded Tissue: 1 H&E slide cut to 4 microns and 6-8 slides cut at 8 microns of BM clot or tissue fixed with 10% NBF fixative on non-charged slides. Please circle tumor for microdissection. Alternatively, the FFPE clock of the BM clot can be sent for sectioning in our lab.

Ship specimen the same day whenever possible, with refrigerated (not frozen) cold pack.

Label all tubes with at least two unique patient identifiers. Slides require one patient identifier. Identifiers include name, DOB, specimen ID# or medical record#.
