^aAn empty cell indicates 'No'. ELISA, enzyme-linked immunosorbent assay; HIT⁺, heparin-induced thrombocytopenia-positive; MOSF, multiple organ system failure; OD cutoff, optical density results above this value are positive (measurement specific for that day of testing); OD titer, optical density of patient result; SICU, surgical intensive care unit.
