92844-0
LaboratoryFLT3 gene internal tandem duplication/Normal [Ratio] in Blood or Tissue by Molecular genetics method
Definition
This term represents a ratio (allelic ratio), following PCR amplification, of a patient's FLT3 gene DNA having internal tandem duplication to that same patient's wild type FLT3 gene DNA not having such duplication. The result is expressed as a signal ratio of peak band intensities and correlates to cells with and without mutated DNA. A ratio of 100.00 is the maximum and indicates a patient specimen has 100% FLT3-mutated tumor with no healthy cells. A ratio between 0.03 and 0.05 indicates low levels of disease.
