The gel test, first reported in 1988, can be used for most areas of blood group serology, but this report deals specifically with ABO/Rh typing and antibody screening and investigation. The technique is simple and quick to perform and the reading of results is standardised and clean with no false-positive reactions being found in antiglobulin tests. Since gel anti-human globulin tests require no washing and the test cards may be sealed during centrifugation, the system is particularly advantageous for 'loosely bound' antibodies and 'high-risk' samples.
