I've been trying to figure out how to correlate the technologists differential with each other. There should be some sort of agreement but I cannot find anywhere on the net what is acceptable and what isn't. the recent diff that we all did the techs neutrophil counts agree right at 15% but the lymphocyte count the difference is something like 32%. I'm not concerned with monos on down as much but this patient had a high eos count which may be throwing things off somewhat. . Is there a better way of doing this? is this a requirement for JCAHO even? What is everyone else doing?
