New test to detect every virus that can infect people and animalsDaniel McCarthy (Author) Published Date : Oct 02, 2015 00:59 IST
Researchers said they created a new test to detect every virus that can infect people and animals, which would eliminate the need to have doctors, perform a number of tests prior to confirming their diagnosis. Researchers at Washington University School of Medicine located in St. Louis, Missouri published the findings.
The senior author of the study said that with this new ViroCap test you do not have to know what virus you are looking for. The test casts a wide net and is able to efficiently detect the viruses present at extremely low levels.
Researchers said they believed the test would be very useful in the situations where a diagnosis has been elusive after the standard testing had taken place or in the situations in which the cause of a severe outbreak of disease is not known.
According to an official news releases, this test sequence then detects viruses in samples of patients as accurately as clinical laboratory systems known as polymerase chain reactions or PCR.
The authors of the study believe this test could be used for early detection of deadly viruses such as Ebola, SARS, Marburg as well as other viruses such norovirus and rotavirus.
To make an evaluation of the ViroCap, the researchers used two groups of biological examples from different patients at the St. Louis Children s Hospital.
In their first evaluation, the standard testing that had relied on genome sequencing detected viruses in 10 out of 14 patients, while this new test found viruses in four children that testing earlier had missed.
The standard testing did not detect parechovirus, influenza B, the virus that chickenpox is caused by and herpes virus 1.
The second round of testing, which included unexplained fevers in children, the standard testing was able to detected 11 viruses in eight children who were evaluated.
The new test found seven additional viruses including one that was respiratory.
In all, researchers said the number of viruses they detected increased 52% with the new test.
