5 - 7 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Whole blood, bone marrow, formalin-fixed, paraffin-embedded (FFPE) tissue block or slides, fresh or frozen tissue
3 to 5 mL whole blood, 1 mL bone marrow, five unstained slides at 10 μM or formalin-fixed, paraffin-embedded tissue block, tissue in RPMI or frozen
0.5 mL whole blood, 0.5 mL bone marrow, two unstained slides at 10 μM
Lavender-top (EDTA) tube, yellow-top (ACD) tube, green-top (heparin) tube, FFPE tissue block or slides, or tissue in RPMI or frozen
Fresh tissue should be placed in RPMI medium or shipped frozen on dry ice. Small samples (eg, punch biopsies, fine-needle aspirates) will also be accepted. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate specimens for each test requested.
Maintain blood, bone marrow or tissue in RPMI at 2°C to 8°C; FFPE specimens at room temperature; tissue at -80°C.
Frozen whole blood/bone marrow; quantity not sufficient for analysis; tumor tissue; broken or stained slides
This profile can be used to detect clonal B-cell immunoglobulin heavy chain (IgH) and immunoglobulin κ light chain (IgK) gene rearrangements in blood, bone marrow, and tissue specimens with combined B-cell clonality detection rate of 99%. The presence of a monoclonal gene rearrangement usually, but not always, reflects the presence of a B-lymphocytic neoplasm, while polyclonal gene rearrangement patterns are found in benign reactive condition. Thus, the results of these studies can assist in the diagnosis of lymphoproliferative disorders.
This PCR assay is able to detect a clonal DNA population at the sensitivity of 5% in a background of polyclonal DNA.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA).
