In cats, the antibodies are already present in the queen's blood before parturition. The blood group antigens are similar in structure to the antigen of a common bacteria in the gut of cats leading to antibody formation. Kittens obtain the majority of their immune response from the colostrum, and are not born with a strong immune response.
The direct Coombs test is used to test for autoimmune hemolytic anemia, a condition where the immune system breaks down red blood cells, leading to anemia. The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells ...
Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder which occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst , leading to an insufficient number of oxygen-carrying red blood cells in circulation . The lifetime of the RBCs is reduced from the normal 100–120 days to just a few days in ...
Therapeutic plasma exchange (TPE) is a novel treatment for immune-mediated diseases and little research has been done for the effectiveness of TPE and patients with IMT. [15] TPE requires removing the patient's plasma which contains antibodies and replacing it with fluids such as sodium chloride , frozen plasma, packed red blood cells, and ...

Treatment depends on the type and cause of the hemolytic anemia. [ 2 ] Symptoms of hemolytic anemia are similar to other forms of anemia ( fatigue and shortness of breath ), but in addition, the breakdown of red cells leads to jaundice and increases the risk of particular long-term complications, such as gallstones [ 4 ] and pulmonary ...
Isoimmunization occurs when the maternal immune system is sensitized to red blood cell surface antigens. The most common causes of isoimmunization are blood transfusion, and fetal-maternal hemorrhage. [16] The hemolytic process can result in anemia, hyperbilirubinemia, neonatal thrombocytopenia, and neonatal neutropenia. [5]
A positive direct antiglobulin test differentiates immune-mediated hemolytic anemia from a nonimmune-mediated cause. Other situations such as liver disease, post-transfusion or immunoglobulin administration, renal disease, and malignancy can cause a positive direct antiglobulin test. [1]
