EGFR Mutation Analysis

Molecular

81235

Test is performed via real time PCR of exons 18-21 of the EGFR gene, done to detect the EGFR-activating mutations and TKI resistance mutations (including T790M) in these exons.

• 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#.
