Hello, Thank you for your contact to health care magic. I understand your concern. If I am your doctor I suggest you to confirm your self as a carrier of typhoid fever, you should do a duodenal aspirate culture or bile culture from gall bladder for Salmonella typhi, the causative agent of typhoid fever. If the culture report says that it is positive you are confirmed as a carrier. If it is difficult to get culture you can also get rapid immunological test typhidot, which is more specific test than that of widal. It also establish the diagnosis of carrier state in you. I will be happy to answer your further concern You can contact me. Dr Arun Tank. Infectious disease specialist. Thank you.
