Smell test to find natural odor in spinal fluid
Part of Hormones & metabolism clinical trials.
This study investigates whether a natural smell can be detected in the fluid around your brain and spine (cerebrospinal fluid) after you sniff it. It aims to understand how smells enter the brain in people with different body weights who are already scheduled for a routine spinal tap.
Summary written for real people, not researchers, by Clin2.
