My husband had a bad pneumonia and admitted to the hospital. He has been having neutropenia and low WBC at 1.7 for several months. The heme-onc physician was scheduled to see him in November but because of the bad fever and tremors, we went to the ER. They admitted him and loaded him with antibiotics the WBC went down to 0.8, the doctor decided to give him neupogen GCSF on the 23 October. The 24 October,WBC still low and the peripheral smear showed several blast cells. The 25 October, the bone marrow had been collected and send out for testing. The doctors apparently have no idea that GCSF was given to him prior to collect the bone marrow. The flowcytometry came back indicated Myelobast present. But the still waiting for more genetic testing. My question would be if the GCSF affected the results of his bone marrow? And how. I would rather them do another bone marrow biopsy to confirm that. Please help shred some light to the issue. Thank you so much.
