Agreement between light-transmission aggregrometry and the results of ADP and CRP-XL stimulation in flow cytometry.

“Abnormal” and “normal” LTA indicates the presence respectively absence of abnormal aggregation wave and/or ATP release, “abnormal” and “normal” flow cytometry indicates abnormal respectively normal response in flow cytometry using -2 SD as cut-off limit. A two-by-two analysis of the agreement using Cohen’s kappa analysis gives an 82% agreement with a kappa of 0.57.
