Static information/disclaimer

NPM1 gene mutation analysis performed for all patients diagnosed with AML based on immunophenotyping results via a reflex testing strategy.

Currently NPM1 MRD monitoring test is not performed.


This test is accredited to ISO 15189:2012

General additional information

Mutation in NPM1 gene is observed in approximately 30% of AML cases and is frequently associated with a normal karyotype. The presence of a NPM1 mutation in the absence of a FLT3 internal tandem duplication (or low level allele ratio) is associated with a more favourable prognosis in AML.

FLT3 (ITD and D835) mutation detection​ is also available for AML patients at diagnosis.
