Background: Mean platelet volume (MPV) is associated with platelet reactivity. Large platelets contain more thrombogenic factors than small ones. Previous studies have shown platelet reactivity in patients with pulmonary thromboembolism (PTE).The aim of this study was to investigate the mean platelet volume (MPV) and platelet count in patients with PTE and healthy control subjects. Methods ...
Introduction ELISPOT assays are primarily used to detect the number of T cells that respond to a given antigen. With that number being absolute for any given donor sample, ELISPOT counts should be similar between laboratories, if subjectivity in counting is avoided. Due to the differences in spot sizes ranging from microns to millimeters, setting cut offs for minimal and maximal spot sizes will...
present study shows once again that standardization and/or recalibration of immunoassays in general is difficult to achieve with a common calibrator alone but needs split-sample measurements with a reference measurement procedure. This stems from the well-known fact that immunoassays may suffer from differences in behavior related to differences between the matrices of calibrators and those of ...
