Tuberculin was found to stimulate cell migration in tuberculosis patient; the migration index made up 1.3 +/- 0.07 in this case.

The findings evidence that spontaneous NBT-test values are regularly growing in all three cell types, and the stimulation coefficients lowers as the process grows in severity at the expense of pulmonary tissue disintegration and bronchial obstruction; these parameters adequately reflect the status of the body specific reactivity.
