Scientists test Vitamin-Based tracking to replace radioactive dyes in blood studies

NCT ID NCT07446647

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares two methods for tracking red blood cells after transfusion: the standard radioactive chromium method and a newer method using biotin (a vitamin). Twenty healthy volunteers will receive their own blood cells labeled with both methods to see if the biotin method works just as well without radiation. The goal is to find a safer, non-radioactive alternative for future blood product studies.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Biotinylated red blood cells, irradiated biotinylated red blood cells, 51-chromium labeled red blood cells, technetium-99m labeled red blood cells

What this could lead to

If successful, this could provide a non-radioactive method to track red blood cells in future studies, improving safety for participants.

What could go wrong

This is a small, early-phase study in healthy volunteers, not patients. The biotin method may not prove as reliable as the current standard, limiting its adoption.
