Diagnostics at your side: laboratory-equivalent analyses from a single sample

AgPlus Diagnostics has announced that the first functional prototype of the handheld AgPlus Diagnostics analytical platform is now fully operational and available for demonstration. Delivering laboratory-grade, quantifiable results within 10 minutes of sample application, the portable AgPlus system has enormous potential in a wide variety of applications where a rapid, accurate and sensitive result is important for fast and reliable decision making.

The AgPlus Diagnostics platform utilises electrochemical immunoassay technology in a patented microfluidic chip format. The unique signalling and measurement system, based on the detection of amplified silver ions by anodic stripping voltammetry, allows extremely sensitive, accurate and quantifiable results to be obtained from a very small sample volume (50 µL) within minutes. The system does not rely on an optical-based detection method, so no sample preparation is required, making it ideal for multiple sample types and for testing in a range of settings.

Getting to the heart of testing
The first fully functional AgPlus technology prototype will demonstrate an assay for human troponin I, which is currently showing a dynamic range of 0.1ng/mL to 50 ng/mL with coefficients of variation (CVs) <20% in a non-optimised format. In addition, AgPlus tests for cortisol and testosterone are currently in development, which will be of value in sports science applications for developing tailored training plans for athletes and to help reduce chances of so-called over training syndrome.
