bacteriophage typing, a microbiological procedure, of epidemiological importance, for distinguishing types within a seemingly homogeneous bacterial species or strain by the use of type-specific bacteriophage.
hLA typing, tests done in order to determine if a patient has antibodies against a potential donor's hLA antigens. The presence of antibodies means that a particular graft will be rapidly rejected. Also used to establish paternity and in forensic medicine.
