Overview
Multiple laboratory abnormalities can be observed in patients with yellow fever, including leukopenia or leukocytosis, bleeding dyscrasias, thromobcytopenia, increased billirubin and hepatic enzymes.
Laboratory Findings
- these can vary depending on the severity and stage of illness. In the first week of the illness, leukopenia might occur; however, leukocytosis also can occur during the second week of the disease. Bleeding dyscrasias also can occur, together with elevated prothrombin and partial thromboplastin times, decreased platelet count, and presence of fibrin-split products. Hyperbilirubinemia might be present as early as the third day but usually peaks toward the end of the first week of illness. Elevations of serum transaminase levels occur in severe hepatorenal disease and might remain elevated for up to 2 months after onset.
