Two commercial primer kits and detection systems, the Roche AMPLICOR
MYCOBACTERIUM test and the Digene primer-probe kit with the SHARP Signal
System, were compared to in-house PCR as well as standard culture
techniques. For the 27 culture-positive specimens, the Roche AMPLICOR
MYCOBACTERIUM test detected 20 specimens, the Digene system detected 19,
and in-house PCR detected 21. Of the 86 culture-negative specimens, 13 were
positive by the Roche AMPLICOR MYCOBACTERIUM test, 16 were positive by the
Digene system, and 21 were positive by in-house PCR. When clinical
situations were evaluated, 11 of 13 culture-negative Roche AMPLICOR
MYCOBACTERIUM test-positive specimens, 10 of 16 culture- negative Digene
system-positive specimens, and 13 of 21 culture- negative-in-house
PCR-positive specimens were diagnosed as true- positive specimens. The
sensitivities of Roche AMPLICOR MYCOBACTERIUM test, the Digene system, and
in-house PCR were 73.81, 69.05, and 80.95%, and the specificities were
97.18, 91.55 and 88.73%, respectively. The positive predictive values were
93.94, 82.86, and 80.95%, and the negative predictive values were 86.25,
83.33, and 88.73%, respectively. For the commercial kits, the Roche
AMPLICOR MYCOBACTERIUM test seems to be more sensitive and specific than
the Digene system. However, the Roche AMPLICOR MYCOBACTERIUM test cannot be
used on nonrespiratory specimens.
