Test Name:

B-Cell IGK Gene Rearrangement

CPT Code:

81264

Turn Around Time:

24 – 72 hours

Clinical Application:

Detection of clonal IGK rearrangements.

Diagnosis and monitoring.

Methodology:

PCR, fragment length analysis. LoD: 1-10%.

Specimen Requirements:

DNA-based assays

Peripheral Blood: Minimum 2 mL in EDTA (purple top) preferred or 2 mL in sodium heparin (green top)

Bone Marrow: Minimum 1 mL in EDTA (purple top) preferred or 1 mL in sodium heparin (green top)

Paraffin Sections: Minimum of 5 sections at 3 microns each

Note: FFPE bone marrow biopsies can result in inadequate DNA due to decalcification (clots sections preferable).

FFPE for Dermatology-related specimens are not accepted.

Storage and Transportation:

Please store and ship specimens at ambient temperatures.
