[Individual tuberculin diagnosis by the prick test].

The graded dermal tuberculin test, as described by N. N. Grinchar-Karpilovsky, which is carried out using 100%, 25%, 5%, and 1% tuberculin solution, is most commonly used for individual tuberculin diagnosis. The use of a prick lancet in a test (the prick test) makes the latter easier and standardized, ensures the equal depth of skin lesion, and requires the less surface of the skin. Assessment of the test (measurement of the diameter of a papule) becomes simpler and it is objective. The Grinchar-Karpilovsky prick test using a prick lancet significantly upgrades the quality of individual tuberculin diagnosis.
