Wbc 2.0, absolute neutrophil 0.6. Lymph are high. Negative for hiv, hep, autoimmune, lupus, vitamin b. Bone marrow biopsy yesterday. What could it be?

Wait for bone marrow. Bone marrow biopsy was done because the cause for the symptoms and other laboratory findings was not clear. Please wait for the bone marrow biopsy results and do not be surprised, if more tests are needed even after that.
