Lactate dehydrogenase (LDH), indirect (unconjugated) bilirubin, haptoglobin, and AST. Learn more here.
Hemolysis is associated with elevated serum levels of leakage products, LDH and AST; reduced levels of haptoglobin (Hp) owing to binding to free Hb and internalization in macrophages (without recycling); and elevation of unconjugated (indirect) bilirubin from breakdown of heme inside macrophages.
