Broad Range Bacterial PCR and Sequencing, Varies
Use
This test is used for detecting and identifying bacteria, including mycobacteria, from normally sterile sources. It is particularly useful for identifying bacteria in specimens where they are visible but other methods have failed. The test is not recommended as a test of cure since nucleic acids may persist after successful treatment. It is optimal for detecting fastidious or slow-growing bacterial infections that do not yield a culture.
Special Instructions
Specimen source is required for test submission. Fresh tissue specimens are preferred over formalin-fixed tissue for optimal results. Specimens should be collected and stored according to specific instructions to avoid false positives from environmental contamination or improper handling.
Limitations
The test does not detect nonbacterial organisms like viruses, fungi, helminths, or protozoa but will detect mycobacteria. False-positive results can occur due to contamination from the environment or skin microbiota. In some cases, sequencing could have extended turnaround times if additional testing is required. Bacterial nucleic acids may persist for long periods, complicating post-treatment assessments.
