The fluorochrome stain is more sensitive than the conventional carbolfuchsin stains;the fluorescent bacilli stand out brightly against the background and can be initially examined at lower magnifications.More fields can be visualized in a short period.In addition,a positive fluorescent smear may be restained by the conventional Ziehl-Neelsen or Kinyoun's procedure,thereby saving the time needed to make a fresh smear.
