Specimen(s):

Blood, Bone Marrow and Tissue

Collection Medium:

	or
Pink top tube 6 mL (K2-EDTA)	or	Yellow top tube 8.5 mL (ACD solution A)

Minimum:

5 mL blood in a pink top or yellow top, 1 mL bone marrow aspirate in a pink top or yellow top, 3 cu mm of fresh frozen tissue or Formalin-fixed, paraffin embedded tissue, body fluids in a pink top or yellow top or lymph node aspirates in RPMI.

Delivery Instructions:

Submit specimen to laboratory as soon as possible after collection.

None

Comments:

DNA extracted from blood, bone marrow mononuclear cells or tissue is examined for rearrangement of immunoglobin heavy chain genes.

NOTE: For patients with chronic lymphocytic leukemia, if analysis for IGH gene somatic hypermutation (or IGH variable region mutation) is desired, please order LAB7503 or LAB7504.
