I am a 76 year old female, always in good health,, with regular check ups, good labs, etc. Today I learned that my regular blood test showed a drop in Hemoglobin from 11.5 to7.5. I have been very tired and weak lately. My doctor has referred me to a GI specialist believing that there is internal bleeding. My mother died in 5 months from ALL. Is this a potential diagnosis? The lab tests did not indicate elevated WBCs.Thanks, (I am also an RN.
