Tuberculin tester and BCG vaccinator, England, 1980-1990
The injector can be used to apply tuberculin to the skin to test whether a person has been exposed to or has immunity to tuberculosis. Six needles puncture the skin. This particular method is known as the Heaf Test – named after Frederick Heaf (1894-1973), a British physician. If, after a week, the patient shows no skin reaction they are at risk from the disease and would need to be vaccinated with the BCG vaccine. The injector can be used for this purpose by using one needle. The needles were probably disposed of or sterilised after use. This model was known as the East-Mark 6 and was made by H G East & Co Ltd.
