What is a Widal Test?
A Widal test is a blood test used to help detect typhoid fever. It checks whether your body has developed antibodies against Salmonella typhi bacteria, which causes typhoid. Doctors usually advise a Widal test in Kota when someone has prolonged fever, weakness, headache, or stomach-related issues.
It is not a fancy test, but still commonly used along with symptoms and other reports to understand if typhoid infection is likely.
Widal Test Parameters
The Widal test measures antibodies against two main antigens of Salmonella bacteria.
- Salmonella Typhi ‘O’ Antigen: Indicates recent or ongoing infection. Higher levels may suggest active typhoid fever.
- Salmonella Typhi ‘H’ Antigen: Shows exposure to infection, past or present. Levels can stay elevated for longer time.
- Salmonella Paratyphi AH Antigen: Helps detect paratyphoid A infection.
- Salmonella Paratyphi BH Antigen: Used to identify paratyphoid B infection.
These values are usually reported as titers and should always be interpreted by a doctor, not self-read.
