Great white sighting: a case of heparin-induced thrombosis with thrombocytosis

With its high sensitivity, specificity, and rapid results, the latex immunoturbidimetric immunoassay is a valuable diagnostic tool, even among patients with a seemingly low pretest probability. This case underscores the guidance imparted by Dr Andreas Greinacher: "[HIT] must be considered if thrombosis occurs or progresses despite effective heparinization even in the absence of thrombocytopenia." Access to rapid and effective laboratory testing reduces the probability of diagnostic error.
