Tiny study aims to fix tricky blood test

NCT ID NCT04266587

First seen Feb 16, 2026 · Last updated May 15, 2026 · Updated 14 times

Summary

This study looked at how to keep a hormone called ACTH stable in blood samples after collection. ACTH is hard to measure because it breaks down quickly. Researchers tested a substance called aprotinin in blood from 10 healthy adults to see if it helps preserve ACTH. The goal was to improve the accuracy of lab tests, not to treat any disease.
