IgG mediated disease
involves extravascular hemolysis binds RBC in WARM temp. RBC consumed by mps results in spherocytes
IgG mediated disease associated with
SLE, CLL and DRUGS-penicillin and cephalosporin
IgM mediated disease
involves intravascular hemolysis Abs attach to RBCs in COLD temp.
IgM is associated with
mycoplasma pneumoniae & Mono
diagnose IgM- most impt for IHA
direct coombs test confirms presence of Abs on RBC already coated with abs= MOst important test for IHA
malaria
infects RBC and liver with plasmodium via ANOPHELES MOSQUITO
parvoB19
infects progenitor RBCs stops erythropoiesis
aplastic anemia
