Haptoglobin Blood Test - More Information
The haptoglobin test, also known as a haptoglobin lab test, measures the haptoglobin blood level.
Haptoglobin (Hp) is a blood protein primarily made by the liver. In the blood, haptoglobin attaches to hemoglobin molecules that are freely floating around (typically after damage to a red blood cell). In this capacity, haptoglobin acts as an antioxidant as unbound hemoglobin can cause damage in the body.
Increased haptoglobin levels are seen in liver disease, infectious mononucleosis (mono) and inflammatory conditions. Sometimes, haptoglobin levels also increase in the setting of diffuse inflammation and conditions in which red blood cells are being destroyed. Low haptoglobin levels can help identify conditions in which red blood cells are being destroyed (e.g. hemolytic anemia) because haptoglobin is being used up to bind up the extra free hemoglobin. Because of its relationship with hemoglobin, this haptoglobin lab test is sometimes ordered with the hemoglobin test or the more detailed CBC test.
To get a haptoglobin test near you, order online and get your blood drawn at the Quest Diagnostics lab that you selected. Once the haptoglobin lab report is ready, it will be available for download. As can be seen on the sample haptoglobin lab report provided above, a numerical result will be reported in mg / dL which can be compared against the reference range provided by the lab.
