NCT ID NCT07321431

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing a new method to measure how well the gallbladder contracts, using protein bars and olive oil instead of a fatty meal. Researchers will compare this to the standard fried-egg test in 120 healthy volunteers. The goal is to find the best time to take ultrasound measurements after eating, to make gallbladder function testing more reliable and consistent.
