What is a Coombs test in dogs?
A Coombs test is performed to detect the presence of antibody against red blood cells. The test is used to support the diagnosis of immune-mediated hemolytic anemia (IHA). Up to 66-75% of dogs with IHA will have a positive Coombs test.
What is Coombs jaundice?
This is the test that is done on the newborn’s blood sample, usually in the setting of a newborn with jaundice. The test is looking for “foreign” antibodies that are already adhered to the infant’s red blood cells (rbcs), a potential cause of hemolysis. This is referred to as “antibody-mediated hemolysis”.
What is detected with Coombs test?
The direct Coombs test finds antibodies attached to your red blood cells. The antibodies may be those your body made because of disease or those you get in a blood transfusion. The direct Coombs test also may be done on a newborn baby with Rh-positive blood whose mother has Rh-negative blood.
What does agglutination indicate in dogs?
Occasionally there will be evidence of red blood cell clumping or agglutination on the slide. This clumping is caused by the presence of immunoglobulins attached to the surfaces of red blood cells. A serum chemistry profile may indicate an increase in bilirubin.
What is the treatment for Coombs positive?
However babies who are Coombs positive may have higher levels of jaundice. High levels of jaundice need to be treated. The usual treatment for jaundice is phototherapy which involves exposing the baby to a light source. Another leaflet is available about Phototherapy.
Is Coombs positive bad?
Coombs positive babies are at higher risk for hyperbilirubinemia. Jaundice should be taken seriously. In rare cases, if the bilirubin level reaches a very high level and isn’t treated, it can cause brain damage called kernicterus. Kernicterus leads to serious lifelong problems.

Where can I get a direct Coombs test?
At Cornell University, we perform a direct Coombs test. In this test, we are looking for antibody adhered to the patient’s red blood cells. For this reason, we need red cells from the patient, preferably asEDTA-anticoagulated blood.
What does the Coombs blood test look for?
Direct Coomb’s Test. The test is looking for “foreign” antibodies that are already adhered to the infant’s red blood cells (rbcs), a potential cause of hemolysis. This is referred to as “antibody-mediated hemolysis”. The two most commonly recognized forms of antibody-mediated hemolysis in newborns are Rh incompatibility and ABO incompatibility.
