Coombs Test - Indirect

The Coombs Test - Indirect, also known as the indirect antiglobulin test (IAT), looks for antibodies in the blood that may react with RBCs, causing immune-related complications. It helps identify antibodies that are freely floating in the bloodstream, which can potentially bind to RBCs. 

The indirect Coombs test is used to screen for blood type compatibility, especially during pregnancy to detect IgG antibodies that are likely to pass on into the fetal blood via placenta leading to hemolytic disease of the newborn(HDN). It checks for Rh incompatibility between the mother and the fetus. Also, it is done in crossmatch screening for blood transfusion to prevent immune reactions and if someone has a blood disorder to identify any harmful antibodies that could be present. 

The Coombs Test - Indirect helps identify antibodies early which supports safe blood transfusion practices between the donor and the recipient and pregnancy management, safeguarding both the mother and the baby.

No special preparation is required for this test. However, a duly Filled Coombs (Direct/Indirect) Form is mandatory. Inform your doctor about all the medications or supplements that you may be taking as these could affect the test results, potentially requiring dosage adjustments or temporary discontinuation before the test. 

Lab test results may vary across laboratories. Interpretation of the test results requires professional expertise. Therefore, do not self-medicate and always consult your doctor to understand your test results correctly. Narrate your complete medical history to help doctors relate your clinical and laboratory findings.
