A newly developed gel centrifugation test for quantification of RBC‐bound IgG antibodies and their subclasses IgG1 and IgG3: comparison with flow cytometry

Abstract

There is a correlation between the amount of RBC-bound IgG and immune hemolysis. The GCT cards that detect the anti-IgG-gamma-chain may be useful to predict hemolysis in patients with a 2+ or 3+ DAT in the GCT. The diagnostic value of GCT cards for IgG subclass testing should be investigated further.
