Whole Blood, Bone Marrow, formalin-fixed paraffin-embedded (FFPE) tissue block or Slides fresh or Frozen tissue

5 mL whole blood or 1 mL bone marrow, five unstained slides at 10 uM or formalin-fixed, paraffin-embedded tissue block, tissue in RPMI or frozen

Lavender-top (EDTA) tube, yellow-top (ACD) tube, green-top (heparin) tube, tan-top (K2-EDTA) tube and pink-top (K2-EDTA) tube, FFPE tissue block or slides, tissue in RPMI or frozen

No special preparation is required for this test. You may eat, drink, and take your medications as normal, unless instructed otherwise by your healthcare provider.

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.
