A Coombs test for hemolytic anemia is a medical test used to measure the presence of antibodies in the blood. It is typically used to diagnose the cause of anemia, which is a condition where there is not enough red blood cells in the body. The test is also used to detect the presence of any autoantibodies that could be attacking the red blood cells.
What is hemolytic anemia?
Hemolytic anemia is a condition in which the body produces too few red blood cells, or the red blood cells that are produced are destroyed faster than they can be replaced. This can lead to a decrease in the oxygen-carrying capacity of the blood and can cause a variety of symptoms, such as fatigue, weakness, and pale skin.
What is a Coombs test?
A Coombs test is a type of blood test used to diagnose hemolytic anemia. It detects the presence of any autoantibodies that may be attacking red blood cells. The test involves taking a sample of the patient's blood and mixing it with a special antibody called anti-human globulin (AHG). If the patient has autoantibodies, they will bind to the AHG and show up as a positive result on the test.
Why is a Coombs test done?
A Coombs test is typically done to diagnose the cause of anemia. It can also be used to detect the presence of any autoantibodies that could be attacking the red blood cells. A positive test result can help guide treatment for the anemia.
What are the risks of a Coombs test?
The risks associated with a Coombs test are very small. The test involves taking a sample of the patient's blood, so there is a risk of infection or bleeding. There is also a small risk of an allergic reaction to the AHG used in the test.
