Introduction

This article explores the significant advancements in immunoassay technology, highlighting innovations in sensitivity, multiplexing, and automation. It emphasizes how these improvements lead to more accurate and efficient diagnostic tools, pushing the boundaries of what's possible in clinical settings for detecting various biomarkers and diseases. What this really means is that labs can now get more reliable results, faster, for things like cancer and infectious diseases[1].

The paper reviews emerging trends in point-of-care immunodiagnostics for infectious diseases, focusing on how these rapid, portable tests are transforming diagnostics outside traditional lab settings. Here's the thing: they are crucial for quick decision-making, especially in resource-limited areas, by offering faster pathogen detection. It's about getting answers right where and when they're needed to manage outbreaks effectively[2].

This comprehensive review delves into various immunoassays used for detecting autoimmune diseases, discussing their principles, applications, and limitations. It highlights the importance of accurate diagnostic tools for early intervention and personalized treatment in autoimmune conditions. Essentially, knowing which test works best helps patients get the right care sooner, preventing disease progression[3].

The article focuses on advances in diagnostic strategies for allergic diseases, particularly molecular allergology and component-resolved diagnostics. It explains how these methods provide more precise identification of specific allergens, allowing for better risk assessment and targeted treatment approaches for individuals with allergies. Let's break it down: instead of just knowing you're allergic, we can now pinpoint exactly what triggers it, leading to more effective interventions[4].

This review discusses the latest progress in multiplexed immunoassays for detecting cancer biomarkers. It highlights their potential to simultaneously measure multiple markers from a single sample, offering a more comprehensive and earlier diagnostic picture for various cancers. What this offers is a more powerful way to detect cancer early and monitor its progression, moving beyond single-marker tests and providing a broader understanding of the disease[5].

The paper reviews microfluidic paper-based analytical devices (PADs) for immunodiagnostics, emphasizing their low cost, portability, and ease of use, making them ideal for point-of-care applications, especially in resource-limited settings. These devices are essentially mini-labs on paper, providing rapid diagnostic results without complex equipment, democratizing access to testing[6].

This review details recent progress in immunochromatographic assays (ICA), also known as lateral flow tests, highlighting their role in point-of-care diagnostics due to their simplicity, speed, and cost-effectiveness. It covers their design principles and applications across various fields, from infectious disease detection to environmental monitoring. These are the quick tests you might use at home, providing immediate, actionable results without needing a lab[7].

The article discusses high-throughput serological testing for SARSCoV2 antibodies, reviewing the methods and their significance during the pandemic. It emphasizes the importance of accurate and scalable antibody tests for understanding population immunity and guiding public health strategies. What this really means is efficiently checking who has been exposed to a virus on a large scale, which is vital for managing widespread outbreaks and planning for future health events[8].

This review provides an overview of biosensors and immunoassays for Alzheimers disease diagnosis, highlighting their potential for early and accurate detection of biomarkers. It explores different sensing platforms and their roles in advancing non-invasive or minimally invasive diagnostic methods. The goal here is to catch Alzheimers earlier, which can make a big difference for patients and families by allowing for timely interventions and management strategies[9].

The paper reviews recent progress in luminescent immunosensors specifically for point-of-care testing. It describes how these sensors offer high sensitivity and rapid detection capabilities, making them excellent candidates for on-site diagnostics across various medical fields.
