What test can be utilized alongside virus isolation for diagnosing ASF?

• A. ELISA test
• B. Hemagglutination-inhibition test
• C. HAD tests
• D. Western blotting

Answer: (C)

The correct choice is the Hemadsorption (HAD) test, as it is a specific and effective method used in conjunction with virus isolation techniques to diagnose African Swine Fever (ASF). The HAD test detects the presence of the ASF virus by its ability to cause erythrocytes (red blood cells) to adhere to infected cells, which is a hallmark of ASF virus activity. This test provides additional confirmation of the viral presence, complementing the findings from virus isolation. In the context of ASF, the use of the HAD test helps to improve diagnostic sensitivity and specificity, allowing for a clearer understanding of an outbreak and guiding veterinary responses. It’s particularly useful because the ASF virus can sometimes be difficult to isolate, and the HAD test helps in confirming the infection non-invasively. Other tests like the ELISA (enzyme-linked immunosorbent assay) or Western blotting could also contribute to the diagnosis but are not typically utilized alongside virus isolation specifically for ASF in the same way as the HAD test provides immediate viral activity insights.
