The Widal Test is a commonly used blood test for diagnosing enteric fever, including Typhoid Fever and Paratyphoid Fever. These infections are caused by bacteria such as Salmonella Typhi and Salmonella Paratyphi.This test works by detecting specific antibodies in the blood that react against the O (somatic) and H (flagellar) antigens of these bacteria. Higher levels of these antibodies, or a rise in their levels over time, may indicate an active infection.The Widal test is widely used, especially in areas where advanced diagnostic methods are not easily available. It provides a simple and accessible way to help identify enteric fever and supports doctors in making timely treatment decisions.
