Test Code LAB3355 NPM1 Insertion MRD Follow Up
Clinical System Name
NPM1 Insertion MRD Follow Up
Description
This quantitative test detects common insertion mutations in NPM1 gene and is intended for post-treatment minimal residual disease monitoring in NPM1-mutated AML. Purified genomic DNA is PCR amplified using double- indexed primers coupled with sequencing adaptors for subsequent next generation sequencing using an Illumina Miseq platform.
Reportable Range: 0.007 – 50.00%
Limit of Detection: 0.003%
Limit of Quantification: 0.007%
Precision near LOD (CV): 54%
