From an article at medicalxpress.com:

Washington University in St. Louis researchers have developed a test that quickly detects the presence of Zika virus in blood.

Currently, testing for Zika requires that a blood sample be refrigerated and shipped to a medical center or laboratory, delaying diagnosis and possible treatment. Although the new proof-of-concept technology has yet to be produced for use in medical situations, the test’s results can be determined in minutes. Further, the materials required for the test do not require refrigeration and may be applicable in testing for other emerging infectious diseases.

Findings from the small study—from Washington University School of Medicine and the School of Engineering & Applied Science—is available online in the journal Advanced Biosystems.

The researchers tested blood samples taken from four people who had been infected with Zika virus and compared it to blood from five people known not to have the virus. Blood from Zika-infected patients tested positive, but blood from Zika-negative controls did not. The assay produced no false-positive results.
