Hi David, I am struggling with a method to method comparison for apheresis platelet counts. Please see below. I wrote this for my data eval and determination of acceptance. ● An acceptable bias or allowable total error of ±7.0% for platelet count was set for this method to method comparison. The mean of the Abbott Cell-Dyn method is 1.5408 with a standard deviation of 0.2248. It is 95% confident that the sample mean falls between 1.47199 and 1.60961 or ±4.5%. The mean of the Coulter DxH 800/600 is 1.5397 with a standard deviation of 0.2376. It is 95% confident that the sample mean falls between 1.467 and 1.612 or ±4.7%. The difference between the two methods are within allowable error for 41 of 41 samples tested. I did a method to method on EP evaluator. Does this sound correct to you?

Hello, Does anyone have a method to method SOP/form they would like to share for transfusion services? Michele
