A new diagnostic test could hold the key to identifying Ebola infections in less than 30 minutes, streamlining detection and potential management of outbreaks in even the most low-resource areas.
The test is based on a protein detection technology known as SERS. It’s portable, works with little more than a blood sample and vials of dried reagents, does not require cold storage and can be utilized even in regions lacking electricity. The test also differentiates Ebola infections from other endemic diseases with similar symptoms.
It was developed by David Sebba, an R&D manager for BD Technologies, and his colleagues. Given that Ebola outbreaks tend to occur in regions that lack lab infrastructure and trained personnel, the test could be revolutionary for healthcare responders. It has already been tested in monkey models and field tested in Senegal and Guinea. Further testing is required, and ongoing.
Though there is an Ebola vaccine on the market, it is an especially tricky disease to root out because of initial detection issues. The disease initially mimics the symptoms of other fever-causing diseases, such as Lassa fever and malaria, making a test that can differentiate a critical necessity.
