BONE NARROW ASPIRATION / BIOPSY

* Rule out malignant metastasis to the bone marrow. The biopsy usually is obtained if an aspirate sample is inadequate to diagnose the disorder. Contraindications * Diagnosis can be made by blood tests alone. Special precautions must be taken when a bone marrow aspirate or biopsy must be done on a child with a disorder of platelet function. ................
