New Test Identifies All Viruses in Infected Humans and Animals
Results published online in September in the journal Genome Research demonstrate that in patient samples the new test - called ViroCap - can detect viruses not found by standard testing based on genome sequencing. The new test could be used to detect outbreaks of deadly viruses such as Ebola, Marburg and severe acute respiratory syndrome (SARS), as well as more routine viruses, including rotavirus and norovirus, both of which cause severe gastrointestinal infections.
The test sequences and detects viruses in patient samples and is just as sensitive as the gold-standard polymerase chain reaction (PCR) assays, which are used widely in clinical laboratories. However, even the most expansive PCR assays can only screen for up to about 20 similar viruses at the same time.
