The diagnosis of acute myeloid leukemia,  the most common leukemia in adult patients with only about 30% long term survivors, and evaluation of response to therapy are done using bone marrow aspirates and biopsies. These are invasive procedures with potential serious complications. The goal of this project is to test non-invasive, painless bioimpedance technology to serve as an adjunctive and convenient biomarker to standard bone marrow biopsies.
