FDA Status
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
Setup Schedule
Tues, fri
Report Available
4-7 days
Reference Range
M. avium DNA | Not detected |
M. intracellulare DNA | Not detected |
Clinical Significance
This test is used to detect the presence of either M. avium or M. intracellulare in a patient's specimen. The use of Real-Time PCR to assay for the presence of M. avium and/or M. intracellulare DNA in clinical specimens allows for rapid patient testing (3 to 4 hours compared to several weeks or more for conventional culture and DNA hybridization) and for distinguishing infections caused by M. tuberculosis or other mycobacterial species.
