Description
Understanding leukemia diagnosis involves analyzing Complete Blood Count (CBC) results, which may reveal decreased White Blood Cell (WBC), Red Blood Cell (RBC), and platelet counts. Excessive bruising and petechiae can also indicate low platelet levels. Red Blood Cells (RBCs) typically survive for about 120 days.
