Test Name: FLT3 Mutation Analysis 


Methodology: Molecular Genetics


Test Description

Detection of internal tandem duplication and exon 20 tyrosine kinase domain (TKD) mutations using bi-directional sequencing. Positive results identify specific TKD mutations or report ITD results quantitatively as percent abnormal ITD peak. Testing may be performed on plasma to increase sensitivity.
