Simultaneously, paper\u2010based lateral flow (LF) immunoassays hold significant relevance for integrated diagnostic applications in the market, but are limited by the low sensitivity of optical detection. To address these challenges, a simple EGOFET integrated with LF paper fluidics are reported to obtain a reusable, highly portable, and cost\u2010effective point\u2010of\u2010care (PoC) test with rapid results (\u224820\u201330\u00a0min). The test is validated for Human Immunoglobulin G detection, achieving a wide linear range, high selectivity, reproducibility, and a low limit of detection of 0.1 f\n                    <jats:sc>m<\/jats:sc>\n                    . The portability of the system is demonstrated in a designed prototype with a miniaturized electronic reader, operating via an adapted USB\u2010connected smart device.
