Molecular

81479

Test is performed via bi-directional sequencing of exons 14 and 17 of the CSF3R gene. It also includes detection of the common mutation T618I (also known as T595I). CSF3R mutations are recently-identified genetic markers detected in 59% of chronic neutrophilic leukemia (CNL) or atypical chronic myeloid leukemia (aCML).

• Bone marrow aspirate: 1-2 mL in EDTA tube (purple top) preferred; ACD (yellow top) acceptable
• Peripheral blood: 5-10 mL in EDTA tube (purple top) preferred; ACD (yellow top) acceptable
• Fresh Tissue: Minimum of 250 mg tissue in RPMI transport media
• Formalin-Fixed Paraffin-Embedded Tissue: 1 H&E slide cut to 4 microns and 6-8 slides cut at 8 microns of BM clot or tissue fixed with 10% NBF fixative on non-charged slides. Please circle tumor for microdissection. Alternatively, the FFPE clock of the BM clot can be sent for sectioning in our lab.

Ship specimen the same day whenever possible, with refrigerated (not frozen) cold pack.

Label all tubes with at least two unique patient identifiers. Slides require one patient identifier. Identifiers include name, DOB, specimen ID# or medical record#.
