<p><b>Bone Marrow Aspirate:</b> 1-2 mL in sodium heparin tube. EDTA tube is acceptable.<br>
<b>Peripheral Blood:</b> 2-5 mL in sodium heparin tube. EDTA tube is acceptable.<br>
<b>Fresh, Unfixed Tissue:</b> Tissue in RPMI.<br>
<b>Bone Marrow/Peripheral Blood Smear or Fresh Tissue Touch Preparation Slides:</b> Minimum 7 slides, labeled with specimen type.<br>
<b>Fluids:</b> Mix in equal parts with RPMI (specimen volume to RPMI ratio of 1:1).<br>
<b>Fixed Cell Suspension:</b> A client-prepared fixed cell suspension is acceptable if received in 3:1 Methanol:Glacial Acetic Acid.<br>
<b>Note for plasma cell enrichment:</b> Will be performed on bone marrow samples unless otherwise directed by the client. Plasma cell enrichment was not validated using peripheral blood; therefore, it is not recommended as a screening specimen unless increased plasma cells are seen on blood smear. Specimens should be received in our laboratory within 72 hours of collection.</p>

Clinical Significance
The panel is performed when IgH is rearranged. This panel is used to identify the IgH partner gene in myeloma, which has prognostic impact. IgH rearrangements are found in 55-70% of myelomas. Together t(4;14), t(11;14), t(14;16) and t(14;20) are found in approximately 35% of myelomas and in 90% of myelomas when there is an IgH gene rearrangement present.
Storage and transportation
Refrigerate specimen. Do not freeze. Use cold pack for transport, making sure cold pack is not in direct contact with specimen. Specimens should be received in our laboratory within 72 hours of collection. NYS clients please provide date and time of collection.
