Cutaneous tuberculosis: a diagnostic dilemma--laboratory inputs

Skinmed. 2012 Mar-Apr;10(2):82-9.

Abstract

Bacterial cultures are the gold standard for diagnosing cutaneous tuberculosis, but there are limitations, despite the advances embracing the innovative technologies, including interferon yrelease assays, enzyme-linked immunoabsorbant assay, and molecular diagnostics, in addition to conventional skin tests and microscopic pathology. The results and their interpretation of cultures are reviewed for use in day-to-day practice.
