Indirect Coombs

The Indirect Coombs test is a laboratory test used to determine the presence of antibodies circulating in a person's blood. This test is typically conducted for the diagnosis and monitoring of conditions such as blood type incompatibilities and autoimmune hemolytic anemia. The Indirect Coombs test is utilized to detect the existence of antibodies within the body. Particularly in cases of blood group incompatibility between a mother and her baby during pregnancy or after childbirth, or in autoimmune diseases, the body generates antibodies against its own red blood cells. This test involves examining a blood sample in a laboratory to determine the presence or absence of antibodies. While the Indirect Coombs test is crucial in identifying the presence of antibodies, it is just one component in establishing a definite diagnosis regarding the disease or condition caused by these antibodies. Doctors evaluate other clinical findings and test results in order to diagnose the disease and create a treatment plan, based on the results of this test.

What Is the Indirect Coombs Test?

The Indirect Coombs test is a laboratory test used to detect antibodies formed against red blood cells in the body. It plays a significant role in the diagnosis of blood type incompatibility, autoimmune diseases, and certain pregnancy-related conditions. In short, it is a blood test conducted to identify the presence of antibodies.

When Is the Indirect Coombs Test Ordered?

1. For monitoring blood type incompatibility:

Especially in cases of blood type incompatibility between a mother and her baby, antibodies in the mother's blood can harm the baby's red blood cells. This test is conducted to monitor the baby's health in such situations.

2. For diagnosing autoimmune diseases:

It can be used in the diagnosis and monitoring of autoimmune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis.

3. For evaluating the condition of a newborn:

It may be performed to assess the risk of hemolytic disease in newborns, particularly when there is blood group incompatibility between the mother and baby.

4. During pregnancy:

When there is an incompatible blood group between the mother and baby during pregnancy, this test may be requested to determine if there are abnormal antibodies present in the baby's blood.
