If a person has aml - acut emyeloid leukemia, what percent of blast would suggest acute myeloblastic leukemia?

Blasts in blood/marr: Blasts are made in the bone marrow. Normally they are under 5% of all the white cells. So a Blast count in the bone marrow over 6% raises the question of Acute leukemia. Anything >30% blast count confirms a diagnosis of acute leukemia. As the blast cell numbers increase in the marrow, Blasts start to appear in the peripheral blood. That is how Leukemia is first diagnosed.
