The<unk>  is a diagnostic skin<unk>  performed in order to determine whether or not a child has been exposed to tuberculosis. Patients who exhibit a negative reaction to the<unk>  may be offered BCG vaccination. The<unk>  is named after F. R. G.<unk> .
Until 2005, the<unk>  was used in the United Kingdom to determine if the BCG vaccine was needed; the Mantoux<unk>  is now used instead.  The<unk>  was preferred in the UK, because it was felt that the<unk>  was easier to interpret, with less inter-observer variability, and that less training was required to administer and to read the<unk> .  The<unk>  was withdrawn because manufacturers could not be found for tuberculin or for<unk>  guns.
The<unk>  may be informally referred to as the six pricks, as it gives six individual injections.
