1 doctor agrees
In brief: Not aware of any
But with advancing age, the response to the skin test may be falsely negative.
There are newer tests available which work by assessing the lymphocytes capacity to respond to antigenic stimulation by a component of the tubercle bacillus, but whether this differs in age groups I do not know.
