Abstract

The detection of Mycobacterium tuberculosis complex DNA by PCR using formalin-fixed paraffin-embedded material has become an integral part of molecular-pathological diagnostics. We describe an approach that enables the detection of contamination by using Mycobacterium szulgai as a positive control, contributing to the reduction of false-positive results.

Der Nachweis von Mycobacterium tuberculosis-Komplex-DNA durch PCR an formalinfixiertem Paraffinmaterial ist heutzutage integraler Bestandteil der molekularpathologischen Diagnostik. Wir beschreiben hier ein Verfahren, welches durch Anwendung von Mycobacterium szulgai als Positivkontrolle Kontaminationen detektiert und so zur Vermeidung falsch positiver Fälle beiträgt.
