Coombs Test - Direct near me in Lucknow










The Coombs Test - Direct is a blood test used to detect antibodies or complement proteins attached to the surface of red blood cells (RBCs). This test helps diagnose conditions where the immune system attacks RBCs, such as autoimmune hemolytic anemia (AIHA), and monitor potential blood compatibility issues during transfusions. It is crucial for identifying causes of hemolysis, especially in newborns and individuals with autoimmune diseases.
The Direct Coombs Test plays a critical role in managing hemolytic disease of the newborn (HDN) by detecting maternal antibodies that might have crossed the placenta leading to the destruction of the baby’s RBCs. This test also helps in investigating transfusion reactions by detecting antibodies attacking transfused RBCs if a patient receives a blood transfusion and the immune system reacts to the donor blood.
No special preparation is needed for this test. You may eat and drink as per your daily routine.








What does Coombs Test - Direct measure?
The Coombs Test - Direct measures the presence of antibodies or complement proteins already attached to the surface of red blood cells. These antibodies are produced by the immune system in response to what it perceives as foreign antigens. A positive result suggests the presence of autoantibodies, indicating that the body is attacking its own red blood cells.
This test is crucial for diagnosing conditions like autoimmune hemolytic anemia, where the immune system targets RBCs, causing their premature destruction. By identifying these antibodies early, doctors can formulate appropriate treatment plans, especially in cases where transfusion reactions or hemolytic disease of the newborn are of concern.
