A blood sample has an elevated bilirubin, low haptoglobin, and low hemopexin.What is the most likely reason for this occurrence?

Question

Quizplus · Accepted Answer

Elevated bilirubin levels, low haptoglobin, and low hemopexin are all indicative of increased intravascular hemolysis. Bilirubin is a breakdown product of hemoglobin that is processed by the liver and excreted in the bile. Low haptoglobin is seen in hemolytic anemia when it binds to hemoglobin released from hemolyzed red blood cells. Hemopexin is a protein that binds heme and is important in preventing heme-mediated tissue damage. Its low levels suggest that it is being depleted due to increased heme release from ruptured red blood cells in the bloodstream. This constellation of findings points to increased intravascular hemolysis, which could be caused by a variety of conditions including autoimmune hemolytic anemia or mechanical damage to red blood cells.
