This does not affect where samples are sent and where your results are issued.
Detection of bacterial genetic material with the use of PCR with primers that are targeted at conserved regions of ribosomal DNA (rDNA).

Samples are referred to Department of Microbiology , Virology and Infection Control at Great Ormond Street. Please discuss with clinical team if you wish this test to be added to sample processing.
Clinical details: 
Some bacterial species are difficult to isolate and culture in the lab or may not grow at all due to prior antibiotic treatment. Molecular diagnostics techniques aid the diagnosis of bacterial infection by detecting bacterial genetic material as opposed to relying on bacterial culture. Some molecular assays are designed for specific bacteria. This provides high sensitivity and specificity but only detects what you are looking for. 16s PCR is a broad ranged assays based on detection of bacterial ribosomal gens (rDNA) designed to overcome this limitation. By using PCR primers that are targeted at conserved regions of rDNA it is possible to design broad-ranged PCRs capable of detecting DNA from most bacterial species.
