Summary

This study looks at whether a quick diagnostic test (BioFire FilmArray) can accurately predict the cause of meningitis or encephalitis in 182 adults. Participants with symptoms like fever, headache, or confusion will have their spinal fluid tested. The goal is to see if the test helps doctors choose the right treatment faster, reduce unnecessary antibiotics, and shorten hospital stays.
