the S Typhi H normal range
S Typhi H Normal Range
The S Typhi H normal range is a titer of 180 or below. A titer of 1160 or higher is considered positive for typhoid fever. The S Typhi H test is an agglutination test that measures the level of antibodies against the H antigen of Salmonella typhi, the bacteria that causes typhoid fever. A positive S Typhi H test indicates that the body has produced antibodies against the H antigen, which is a sign of an active or past infection with typhoid fever.
The S Typhi H test is not as sensitive as other tests for typhoid fever, such as blood culture or PCR. However, it is a relatively inexpensive and easy test to perform, and it can be helpful in diagnosing typhoid fever in areas where these other tests are not available.
If you have a positive S Typhi H test, it is important to see a doctor to confirm the diagnosis and to get treatment. Typhoid fever is a serious illness that can be fatal if not treated.
Here are some additional things to keep in mind about the S Typhi H normal range
* The normal range can vary slightly from lab to lab.
* The S Typhi H test may be falsely positive in people who have been vaccinated against typhoid fever or who have had a previous infection with typhoid fever.
* The S Typhi H test may be falsely negative in people who have recently been infected with typhoid fever or who have a weak immune system.
If you have any questions about the S Typhi H normal range, please talk to your doctor.
