Polymerase chain reaction-based (PCR-based) and enzyme-linked immunoabsorbent assay (ELISA) methods are now applied in the detection of major food-borne pathogens.

We measured the plasma PTX3 levels in 196 patients with heart failure and 60 control subjects without heart failure by sandwich enzyme-linked immunosorbent assay.
