The Widal test is a serological test used to find out if someone has typhoid fever, which is an infection caused by Salmonella typhi. The test checks to see if there are antibodies in the blood against some of the antigens that the bacterium makes.
A Widal test titer of 1:20 for the O antigen is considered a normal or negative result, and a titer of 1:160 or higher is usually considered a positive result for typhoid fever. But the way Widal test results are interpreted can be different depending on the lab and testing methods used, as well as the person's clinical presentation and ability to interpret the test results in the appropriate clinical context.
However, it is important to note that a single test result is not sufficient to diagnose typhoid fever. Other tests, such as blood cultures or PCR tests, may also be needed to confirm the diagnosis.
I think you should talk to a doctor who can look at your husband's test results in the context of his overall health and symptoms and, if necessary, give him the right treatment.
