A platelet count below 50,000/µL is a common threshold for considering a pre-procedure platelet transfusion to temporarily correct the hemostatic defect.
Do not confuse this with anemia or anxiety. While important, a low hemoglobin level does not cause immediate procedural bleeding, and NPO status is not required for a standard bone marrow biopsy performed under local anesthesia.
