I seek a clarification on the recent article(1) on this topic. My
Laboratory staff informs me that the only Mantoux preparation available
on the market is one which contains 10 TU/0.1 ml of PPD-RT 23 (Span
Diag-nostics, Surat). Yet the company literature states that an
induration of 10 mm or more is a positive test. How do I interpret the
Mantoux test if I use this 10 TU preparation? Is the Mantoux preparation
of Guindy Lab Chennai made available to the private sector too?
