Key Points:

  • Repurposed credit card-sized technology simplifies diagnostic stool tests by measuring fecal bile acids, essential for identifying gastrointestinal conditions.
  • This technology allows for easier sample collection, transport, and analysis, reducing costs and improving safety.

In a recent study, researchers repurposed credit card-sized technology to improve and broaden the use of diagnostic stool tests. These tests are essential for identifying gastrointestinal conditions, as they measure fecal bile acids that play a crucial role in digestion and absorption of lipids. Traditionally, stool tests require complex storage conditions and specialized shipping methods to prevent sample degradation. However, the new technology developed by Dr. Melinda Engevik and her team eliminates these barriers. By using dried fecal spot (DFS) cards, samples can be collected, stored, and shipped at room temperature, simplifying the process and reducing costs.

The study showed that DFS provides reliable results on bile acid content comparable to traditional methods, offering advantages of easier storage, transport, lower costs, and improved safety. This innovation has the potential to revolutionize sample processing in remote settings and global healthcare, allowing for easier sample collection and transport for analysis. The researchers are excited about the possibilities this technology opens up for measuring other fecal compounds and those produced by microorganisms, promising a significant impact on diagnostic testing and healthcare accessibility worldwide.
