Recently, I went for routine labs. My doc phoned to say that I had MAC in the bloodstream (disseminated I guess). He did follow-up labs which show anemia and poor retic counts, leading him to suspect MAC in the marrow. What does this mean in real life?
"Disseminated" means all over the body, which INCLUDES the bone marrow. Sometimes you can find MAC in the marrow before blood cultures turn positive. So MAC in the marrow is no worse than "disseminated MAC".
