Haptoglobin (HP) Test

What is Haptoglobin (HP) Test?

The Haptoglobin (HP) Test is an important diagnostic tool for diagnosing a variety of diseases, mainly hemolytic anemia. It is a test that measures the amount of haptoglobin in the bloodstream, which is a protein produced by the liver. The haptoglobin is responsible for binding to hemoglobin released into the bloodstream from red blood cells.

Why Haptoglobin (HP) Test is Performed?

The Haptoglobin (HP) Test is primarily performed to assess the presence of hemolytic anemias, autoimmune hemolytic anemia, or other conditions that lead to an increased breakdown of red blood cells. It is also used to determine the cause of anemia.

Procedure for Haptoglobin (HP) Test

The procedure of the Haptoglobin (HP) Test generally involves drawing a small volume of blood, typically from the arm. The blood sample is collected in a special tube and sent to a laboratory for analysis. The laboratory technician will analyze the sample for the presence of haptoglobin. The results are typically sent back to the healthcare provider within a few days.

Types of Haptoglobin (HP) Test

There are two types of Haptoglobin (HP) Tests: the Quantitative and Qualitative Tests. The Quantitative Test measures the exact concentration of haptoglobin in the blood. The Qualitative Test just determines whether the haptoglobin is present in the blood or not.

Risks Associated with Haptoglobin (HP) Test

  • The only risk associated with the Haptoglobin (HP) Test is a small amount of pain and slight bleeding at the site of blood collection.
  • Incertain cases, if the test results are positive for anemia, further investigations may be necessary.

Preparation for Haptoglobin (HP) Test

In most cases, no special preparation is required for the Haptoglobin (HP) Test. However, it is advised to inform the healthcare provider about any medication being taken beforehand.

When Haptoglobin (HP) Test is Used?

The Haptoglobin (HP) Test is mainly used to diagnose hemolytic anemia caused by infection, autoimmune disorders, or other causes. In some cases, it is also used to monitor the effectiveness of treatment for hemolytic anemia.
