A painless skin patch simplifies diagnostic tests
Many diagnostic tests require blood, but NIBIB-funded researchers have developed a skin patch with tiny needles that painlessly collect interstitial fluid (ISF) for testing. Diagnostic tests can measure trace amounts of essential proteins or hormones in the blood called biomarkers. High or low levels of biomarkers are specific indicators for a disease. In the new test, a unique paper on the patch’s backing stores small amounts ISF, where it remains for analysis. Researchers think the ISF patch will simplify diagnostic testing and enable the continuous monitoring of biomarkers. Monitoring biomarkers is crucial because doctors routinely use them to diagnose and monitor patients at risk for cancer, heart disease, and diabetes.
