Safety Study Investigating if Concomitant Injections of C-Tb and 2 T.U Tuberculin Affect Induration Responses

Summary

A new, more specific skin test to detect tuberculosis has been developed by Statens Serum Institut in Denmark. The new skin test is named C-Tb and like the current Tuberculin a positive test result will show as redness and/or induration at the injection site, while a negative test will leave no reactions. The aim of this study is to address if the size of induration and the sensitivity of C-Tb is influenced by concomitant injections of C-Tb and Tuberculin. Furthermore, the intention is to evaluate the safety of C-Tb when injected alone or concomitantly with Tuberculin.
