Which urinary finding is associated with intravascular hemolysis?

Explanation:
Intravascular hemolysis releases free hemoglobin into the bloodstream, and once haptoglobin capacity is exceeded, this free hemoglobin is filtered by the kidneys and appears in the urine as hemoglobinuria. This distinguishes it from hematuria (intact red cells in urine), pyuria (pus/WBCs in urine), or proteinuria (protein in urine from kidney damage). So the urinary finding tied to intravascular hemolysis is hemoglobinuria.
