High-sensitivity, quantitative immunoassays have long been associated with laboratories and multi-hour workflows. Emerging technologies such as the capillary-driven immunoassay (CaDI) platform are challenging that assumption.

Understanding the differences begins with a closer look at how a traditional ELISA functions, followed by how CaDI reimagines the same core chemistry within a rapid, cartridge-based system. Viewed side by side, these approaches reveal how each supports distinct applications.
