Haptoglobin with hemolysis
WebOne used a haptoglobin cutoff of less than 25 mg/dL and demonstrated 83% sensitivity and 96% specificity for intravascular hemolysis (JAMA 1980;243:1909-11). Another used a haptoglobin cutoff of less than 28 mg/dL and noted 91.8% sensitivity and 98.4% specificity for intravascular hemolysis (Eur J Clin Invest 2006;36:202-9).
