Coombs test is a laboratory test used to detect the presence of antibodies that are attached to the surface of red blood cells. It is used to diagnose autoimmune hemolytic anemia, which is a condition where the body's immune system attacks and destroys red blood cells. The test involves mixing a sample of the patient's red blood cells with antiserum, or antibodies, and observing whether the cells agglutinate, or clump together. If the cells agglutinate, it is an indication that antibodies are present on the surface of the cells.
How is the Coombs Test Performed?
The Coombs test involves two parts: the direct and indirect Coombs tests. The direct Coombs test involves mixing a sample of the patient's red blood cells with antiserum, or antibodies, and observing whether the cells agglutinate, or clump together. If the cells agglutinate, it is an indication that antibodies are present on the surface of the cells. The indirect Coombs test involves mixing a sample of the patient's serum with a sample of normal red blood cells, and observing whether the cells agglutinate. If the cells agglutinate, it is an indication that antibodies from the serum are present in the patient's blood.
What Conditions Does the Coombs Test Diagnose?
The Coombs test is used to diagnose autoimmune hemolytic anemia, which is a condition where the body's immune system attacks and destroys red blood cells. It can also be used to diagnose other conditions, such as transfusion reactions and hemolytic diseases of the newborn.
What Are the Risks Associated With the Coombs Test?
The Coombs test is generally considered to be a safe test, with a low risk of complications. However, there is always a slight risk of a reaction to the antiserum used in the test. In rare cases, a patient may experience an allergic reaction or other side effects.
