EPIDERMAL GROWTH FACTOR RECEPTOR (EGFR) MUTATION ANALYSIS

Specimen Required
One Formalin fixed paraffin embedded tissue

Alternate Specimen
Slide: Cut one 3-5 um tissue section for H & E stain. Cut 3-5 10 µm sections on non-charged regular glass slides for microdissection. The slide should not be baked or melted. A new blade must be used for each paraffin block, for cutting to prevent cross contamination.
