Firstly in absence of symptoms, there is nothing to worry about as of now. QFT results are based on the proportion of IFN- released in response to tuberculin as compared with mitogen, The TB1-NIL tube specifically detects CD4+ lymphocyte reactivity, specifically stimulated by the TB1 antigens. A qualitative result (i.e., Negative, Positive, or Indeterminate) is based on interpretation of the four values, Nil, TB1 minus Nil, TB2 minus Nil, and Mitogen minus Nil. Use of LPTs is effective in the early identification of disease risk, and in secondary prevention of disease.
