Serum tryptase and whole blood tryptase levels in patients with AML at diagnosis and at the time of complete hematologic remission (CR).

The levels of serum and whole blood tryptase were analyzed in patients with AML at diagnosis and after the patients had entered CR. As visible, tryptase levels decreased in response to chemotherapy, and, in the majority of the cases, the levels were within the normal range (< 15 ng/mL, dotted line) after patients had achieved a CR.
