CPT® Code 83010

Haptoglobin (Hp) is a crucial protein produced by the liver, encoded by the HP gene. Its primary function is to bind free plasma hemoglobin that is released into the bloodstream, particularly during the breakdown of red blood cells. This binding process is essential as it facilitates the removal of free hemoglobin from circulation, which is then filtered out by the spleen. By preventing the accumulation of free hemoglobin, haptoglobin plays a significant role in protecting the kidneys from potential damage and minimizing iron loss from the body. The quantitative measurement of haptoglobin levels, as indicated by CPT® Code 83010, is primarily utilized in clinical settings to screen for or monitor conditions such as intravascular hemolytic anemia. This includes scenarios like transfusion reactions, autoimmune hemolytic anemia, and acute inflammatory responses. The test involves obtaining a blood sample through venipuncture, which is a separately reportable procedure. The serum or plasma obtained from the blood sample is then analyzed using a quantitative immunoturbidimetric method to determine the haptoglobin concentration. Understanding haptoglobin levels can provide valuable insights into a patient's health status, particularly in relation to hemolytic disorders.
