Basic research into better understanding of pathogenic virus and breakthrough drug discoveries will help head off diseases. EY's new reagents for carbohydrate, immunological research, and, more recently, DNA-related reagents are catered specially to these areas. EY was the first to introduce lectin and lectin conjugates for basic research and is still the world's largest supplier of labeled lectin conjugates.

Synergy from the latest advances in bioassay technology, optics, computing and electronics has made it possible to obtain quantitative analytic test results instantly. This advance is the culmination of decades of research, starting with EY's patented "Immunological Determination" method (1981) and continuing with today's multiple analyte simultaneous assays.

In the last ten years, EY has used its patented "Directed Flow Diagnostic Device" (1991) to make HIV 1+2 rapid assay tests using colloidal gold as a signal generator in the membrane-based immunoassay device. Progress continues afterwards, and it introduced a simpler and faster rapid test. The latest design increases the tests' sensitivity and specificity and yet will be available at a still lower price.
