I den perifere blodreduktion på ≥3 logaritmer i antallet af Bcr - ABL- transkriptioner (målt ved real- time kvantitativ reverse transkriptase PCR assay) over for en standardiserede baseline.
Major molecular response criteria: in the peripheral blood reduction of ≥ 3 logarithms in the amount of Bcr-Abl transcripts (measured by real-time quantitative reverse transcriptase PCR assay) over a standardised baseline.
