What diagnostic test can be used for ASF besides virus isolation in macrophage?

The diagnostic test that can be used for African Swine Fever (ASF) besides virus isolation in macrophages is the Hemadsorption (HAD) test. This test is particularly relevant in veterinary diagnostics for ASF because it can help detect the presence of the virus by observing how it interacts with red blood cells. Hemadsorption occurs when specific viruses, including ASF virus, cause infected cells to bind to red blood cells, leading to observable changes that can be monitored in a laboratory setting.

The HAD test is beneficial as it provides a reliable method to identify the presence of the ASF virus quickly, complementing other diagnostic methods like virus isolation, which may take longer. Other options listed, such as ammonia tests, CT scans, and fecal testing, are not appropriate for diagnosing ASF. Ammonia tests are more likely related to liver function or toxicity in animals, CT scans are primarily used in human medicine and not practical for ASF diagnosis, and fecal testing is not relevant since ASF does not typically manifest through fecal shedding in its diagnostic approaches. Thus, the HAD test stands out as a pertinent alternative diagnostic tool for ASF.
