FcγRIIa amplifies platelet activation and higher platelet FcγRIIa identifies patients at greater risk of subsequent cardiovascular events. We report the accuracy and precision of a modified test to quantify FcγRIIa on previously fixed platelets (pFCG test). An antibody clone (5G1) was developed after exposure of mice to formaldehyde treated FcγRIIa.

Consequently, there is a need for new biomarkers that can identify PCA at any stage of progression while limiting the number of false positives. The use of autoantibody signature-developed biomarkers has proven to be an effective method to solve this problem.

Predicting which patients will develop a recurrence is a significantly growing, unmet medical need.
Methods: Archival formalin-fixed, paraffin-embedded (FFPE) primary adenocarcinoma tissues obtained at surgery were retrieved from 74 patients with CRC (15 with stage I disease and 59 with stage II disease) for Training/Test Sets.
