Note:
The only sample that was positive by MGGAP PCR and negative by MGMR PCR had a very low bacterial load. In addition, MGGAP PCR was performed earlier on a fresher sample while MGMR PCR was performed several weeks later and thus DNA degradation could have contributed to the discordant result between these tests.
