Thought this might be helpful. I'm sure most people here might know this stuff already but I didn't. I contacted my oncologist and he gave me these guidelines for counts cince my hep specialist seemed to disagree and wanted to cut my dose of interferon. Makes ya go hummm??
If the ANC goes under 500 the infection risk increases - however, if there are a lot of monocytes, that lessens the risk. If the hemoglobin goes under 8 or if you are getting more symptomatic with headaches, fatigue, etc, then treatment would be necessary. Weekly shots of procrit (or Epogen) should be considered to help keep the red blood cell level up, and if the ANC falls too low, Neulasta shot every two weeks can keep the white cells out of the danger range.
If the platelet count goes below 25,000, then you will bruise more - not really dangerous until under 10,000.
