What this Trial Is About
Researchers are evaluating the ability of the ShuntCheck test to detect flow or no flow in ventriculoperitoneal shunts among patients with asymptomatic normal pressure hydrocephalus. This observational study aims to determine the tests accuracy in identifying shunt function without symptoms, providing important information for routine care. Participants will undergo the ShuntCheck diagnostic test, which uses an FDA-cleared device that analyzes shunt flow through transcutaneous thermal convection. The study involves a single testing approach, with some assessments measuring the test performed twice to evaluate specificity and negative predictive value. During the study, participants will be monitored through the ShuntCheck test and routine clinical visits. Researchers will measure the specificity and negative predictive value of the test at 15 minutes and also assess these outcomes when the test is performed twice at 60 minutes. The study is sponsored by the University of South Florida and continues until November 2026.
