oa South African Medical Journal - The multiple-puncture tuberculin reaction



The specific tuberculin reaction is defined as a delayed hypersensitivity reaction to products of mammalian tubercle bacilli occurring in subjects previously sensitized by infection with the homologous organism, and it is suggested that the term 'positive' be abandoned in favour of ' significant' or 'specific', and 'insignificant' or 'non- pecific', to allow for cross-reactions due to atypical mycobacterial infection, while 'non-reactor' is proposed as a suitable substitute for �negative'.
