The Nadir or low point of absolute neutrophil count is usually seen after about 7-10 days of the chemo cycle. Usually this returns to normal or near normal and the next chem. Cycle is started. But a nadir ANC of 500 is a grade 3 or 4 risk (high risk) for infection and should be ideally supported with Neulasta, unless there is a contraindication such as sickle cell disease, possibility of splenic rupture, tumor having granulocyte-colony stimulating factor (G-CSF) receptors which get activated by Neulasta, or other such conditions. In these cases usually packed cell transfusion is given.
Hope this helps. Take care!

Thanks for the information. This is what my nurse colleagues & I thought. We just wonder why a physician would not do whatever possible to hopefully prevent complications of neutropenia especially since this was cycle one. There are no known contraindications for Neulasta support.
