Physicians can order the test for patients with idiopathic meningitis or encephalitis with unknown etiology. Testing is performed on cerebrospinal fluid. The testing process takes around 72 hours and results are reported back within one to two weeks. Charles Chiu, director of UCSF's Viral Diagnostics and Discovery Center, most recently described the test at a conference in February.
