Haptoglobin, Serum is a test used to measure the levels of haptoglobin, a protein produced by the liver that binds to hemoglobin released from damaged red blood cells. This analysis is an important tool for diagnosing hemolytic anemia, as low haptoglobin levels may indicate excessive breakdown of red blood cells. It is also used to evaluate inflammatory conditions and liver diseases. A blood sample is collected and analyzed in the laboratory, providing valuable information about the patient’s health and helping doctors make appropriate treatment decisions.
