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?
I am learning about instrument correlation right now, and am wondering a couple of things.
1. what parameters of a CBC must be monitored? I have heard that CAP only requires the WBC, RBC, HGB, HCT, PLT, and MCV but not the differential.
2. When you have a parameter failing the allowable error, where do you start? What is the best way to see which anaylzer is the one at fault for the fail? And once you establish, how do you get to match if you have done all the checks for maintance and QC is looking good for the faulting one...do you adjust the cal factor so they are alined?
3. When dealing with different manufacturers for your analyzer comparison, they should match the total allowed error regardless of type and brand of hemo analyzer?
Thanks for the help!
Does anyone have policies, processes, procedures to share regarding how you deal with gram stain discrepencies between technologists and when you would perform a corrected report.
Also if you have any references regarding how and why you use this criteria that would be helpful also.
