Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
This report is negative for typhoid antigens
But a single value is not important and may be negative in the initial week. It may not exclude typhoid.
It needs a repeat rising titre to label it as Typhoid.
Presently the doctor should manage by clinical picture. please be guided by your treating doctor.
Avoid any outside/ uncooked food. Use easily digestible, home cooked food which is non-oily, non-spicy.
keep her well hydrated with adequate water intake and looking for any losses in stool/ vomits.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries. Please ask for any clarifications before closing and rating this answer.
Thank you and Good luck!
