Introduction: The Urgency of African Swine Fever Detection

African swine fever (ASF), caused by the African swine fever virus (ASFV), has posed a severe threat to global pig farming and food security. The disease, characterized by high mortality rates and rapid transmission, demands prompt and accurate detection to prevent outbreaks. As swine producers and veterinary agencies worldwide seek reliable diagnostic tools, African swine fever virus test methods have evolved to meet the need for speed and precision. This article explores the latest in ASF detection, with a focus on Sabervet’s rapid test products from Antigenne, which have revolutionized ASF test practices with their efficiency and accuracy.

Traditional vs. Modern ASF Detection Methods

Limitations of Conventional Techniques

Traditional diagnostic approaches for ASF, such as polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA), have long been the gold standard. While PCR offers high sensitivity, it requires specialized laboratories, trained personnel, and hours to generate results, making it less suitable for on-site screening. ELISA, though widely used, also suffers from time-consuming procedures and dependency on laboratory infrastructure. These limitations have spurred the development of rapid diagnostic tests (RDTs) that enable point-of-care detection.

The Rise of Rapid Immunochromatographic Assays

In recent years, immunochromatographic technology has emerged as a game-changer in African swine fever diagnostics. RDTs based on this technique allow for visual interpretation of results within minutes, making them ideal for field use. These tests work on the principle of antigen-antibody binding, where specific proteins from ASFV or antibodies produced by infected pigs react with labeled reagents to form visible bands on a test strip.

Antigenne’s Sabervet: Redefining ASF Rapid Testing

Product Overview

Antigenne, a leading developer in veterinary diagnostics, has introduced two groundbreaking Sabervet rapid tests for ASF: the African swine fever virus antibody rapid test and the African swine fever virus antigen rapid test. Designed for ease of use and speed, both tests deliver results in just 10 minutes, addressing the critical need for immediate screening in outbreak scenarios.

Key Features of Sabervet Rapid Tests

1. Unmatched Speed and Convenience

   The Sabervet tests eliminate the need for complex equipment or laboratory settings. Users can perform the test on-site by simply adding a blood or serum sample to the test device, followed by a buffer solution. The results are visible within 10 minutes, allowing for rapid decision-making to contain potential outbreaks. This speed is particularly crucial in regions where ASFV test accessibility is limited.




2. Exceptional Diagnostic Accuracy

   Antigenne’s tests boast impressive diagnostic sensitivity and specificity. The antibody rapid test achieves a sensitivity of 98.00%, ensuring that nearly all infected cases are detected, while the specificity stands at ≥97.50%, minimizing false-positive results. For the antigen rapid test, these metrics mirror the antibody test’s performance, making them reliable tools for confirming ASF infection. Such accuracy is vital in distinguishing ASF from other swine diseases, such as classical swine fever, to avoid unnecessary culling.




3. Immunochromatographic Technology at Its Core

   Both tests employ a double-antibody sandwich or indirect antibody detection format using immunochromatography. This technology involves a nitrocellulose membrane strip coated with specific antibodies against ASFV antigens or recombinant ASFV proteins. When a sample is applied, it flows through the membrane, and if ASFV antigens or antibodies are present, they bind to the labeled reagents, forming a colored band that indicates a positive result. The clear separation of control and test lines ensures easy interpretation, even for users with minimal training.

Applications and Advantages in Field Settings

Pandemic Preparedness and Response

During ASF outbreaks, early detection is key to preventing the virus from spreading to healthy herds. The Sabervet rapid tests enable farmers, veterinarians, and animal health agencies to conduct mass screening efficiently. For example, in regions experiencing an ASF surge, these tests can be used to quickly identify infected pigs, allowing for timely isolation and culling measures. The portability of the tests means they can be deployed in remote areas where laboratory access is limited, addressing a critical gap in African swine fever surveillance.

Routine Screening and Biosecurity

Beyond outbreak response, the Sabervet tests are invaluable for routine biosecurity measures. Pig farms can use them to screen new arrivals, monitor herd health, and ensure compliance with international trade standards. The ability to perform ASFV test on-site reduces reliance on external laboratories, saving both time and costs. Additionally, the tests’ high specificity helps prevent false alarms, which can be costly for producers.

Comparative Analysis: Sabervet vs. Competitors

When compared to other rapid tests on the market, Sabervet stands out for its combination of speed, accuracy, and user-friendliness. Many competing RDTs have lower sensitivity, leading to missed cases, or require more complex steps that increase the risk of operator error. Antigenne’s commitment to quality control ensures batch-to-batch consistency, a feature that is often lacking in cheaper alternatives. The company’s rigorous validation processes, including testing against a wide range of ASFV strains, further solidify the tests’ reliability in diverse field conditions.

Conclusion: A New Standard in ASF Diagnostics

The ongoing threat of African swine fever demands innovative diagnostic solutions, and Antigenne’s Sabervet rapid tests have emerged as leaders in this field. By combining immunochromatographic technology with exceptional accuracy and unprecedented speed, these tests address the long-standing challenges of ASF detection. Whether for emergency outbreak response or routine herd health management, the Sabervet African swine fever virus antibody rapid test and African swine fever virus antigen rapid test provide a trustworthy tool for veterinarians and producers worldwide. As ASF continues to evolve, such advancements in rapid diagnostics will remain essential in the fight to protect global swine populations and food supply chains.
