What is Indirect Coomb's Test ?
The Indirect Coombs Test, also known as the Indirect Antiglobulin Test (IAT), is used to detect antibodies against red blood cells in the blood serum. This test is especially important in prenatal care and blood transfusions to identify potential incompatibility issues. Unlike the Direct Coombs Test, which checks for antibodies attached to red blood cells, the Indirect Coombs Test identifies free-floating antibodies in the blood that may attack transfused red blood cells or a fetus’s red blood cells. Clinicians may order an Indirect Coombs Test to: Screen for blood compatibility in transfusions: Before a blood transfusion, the Indirect Coombs Test ensures compatibility by detecting antibodies in the recipient's blood that may react with donor blood, helping to prevent adverse transfusion reactions. Assess Rh compatibility in pregnancy: In Rh-negative mothers, this test detects antibodies against Rh-positive blood, which can be crucial for fetal health. If antibodies are found, the fetus is at risk of hemolytic disease, making this screening vital for early intervention. Diagnose hemolytic disease of the newborn (HDN): When an Rh-negative mother has antibodies against her Rh-positive baby’s red blood cells, the Indirect Coombs Test helps monitor and assess the risk of HDN, enabling necessary treatments to protect the baby. Detect unexpected antibodies in pre-surgical patients: Prior to surgery requiring potential blood transfusions, the Indirect Coombs Test helps identify any unexpected antibodies in the patient’s blood that could complicate transfusions. Evaluate autoimmune disorders affecting red blood cells: Sometimes, the Indirect Coombs Test is used to detect antibodies that may be part of an autoimmune disorder, contributing to conditions like autoimmune hemolytic anemia.
