Test identifies any infection from any sample in hours

By LabPulse.com staff writers

Scientists from the University of California, San Francisco developed the test, which requires no special handling or processing for each specific bodily fluid and uses next-generation DNA sequencing technology. It accounts for all DNA in a single sample. The test uses a new analytical software application to compare DNA sequences in the sample to genomic databases that cover all bacterial, viral, parasitic, or fungal infections from any species.

Procalcitonin test signals infection in heart attack patients
