Discriminatory performance of positive urine hemoglobin for detection of significant hemolysis in patients with continuous-flow left ventricular assist devices

Serum LDH is significantly associated with U-Hb levels. Absence of U-Hb appears to efficiently exclude significant hemolysis in patients with CF-LVADs. Because it can be performed by patients at home, hemoglobinuria monitoring may enable more intense surveillance and earlier diagnosis of device thrombosis.
