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.
