Intravenous Creatinine Infusion Quantifies Kidney Function in Clinical Trial
Traditional clinical visits usually estimate renal filtration rates using a standard blood sample that measures baseline creatinine, a waste product generated by normal muscle breakdown and cleared by the kidneys. While a 2023 phase of the LOWIO study explored this by administering oral creatinine via a meat meal, the current phase shifts to intravenous delivery. This intravenous approach ensures researchers know the exact dose entering the bloodstream, removing variables tied to digestion and absorption.
Two-Day Trial Protocols and Blood Sampling Procedures
The clinical investigation splits into two distinct, single-day observation periods for participants. On the intervention day, medical staff infuse the 500 mg creatinine glucose solution through an intravenous catheter. Researchers then track the resulting shifts in blood chemistry and urinary output through repeated blood draws via an indwelling venous catheter alongside continuous urine collection.
During the control day, participants receive the identical glucose solution without any added creatinine. Comparing the two days gives investigators a clear baseline to isolate how the body processes the exact infused quantity.

Frequently Asked Questions About the LOWIO Study
Why does the study use intravenous creatinine instead of oral ingestion?
Oral administration via food introduces variables related to digestion rates and individual gut absorption. Delivering the compound directly into the bloodstream guarantees that researchers know the exact amount entering circulation at a precise time.
What does the intravenous dose do to the body?
The 500 mg creatinine infusion roughly doubles the amount of the substance normally present in a participant’s system. This controlled elevation allows scientists to observe how efficiently the kidneys process and clear an acute surplus.
How can individuals contact the research team?
People interested in learning more about the trial or participating can send inquiries directly to the study staff at pharmakologie-studien@uk-koeln.de before the project concludes at the end of 2026.
