Preanalytical conditions can interfere with M. tuberculosis detection by PCR in respiratory samples
Clinics; 73 (), 2018
OBJECTIVES: Tuberculosis is one of the most prevalent infections in humans. Although culture is the reference for diagnosis, its sensitivity is compromised, especially in paucibacillary samples. Because polymerase chain reaction (PCR) amplifies mycobacterial DNA, it is more sensitive than culture for the...
