Your widal test
result is negative means you are not suffering from typhoid fever
.Rest of the things mentioned are just to help interpretation of report.So you need to worry about these things.
Widal test is done for diagnosis of typhoid fever or salmonella
This test should be done between 7 -10 days of fever.It has no significance if test is performed in less than 7 days of fever.
The Widal test is positive if Typhi O antigen titer is more than 1:160 in an active infection, or if Typhi H antigen titer is more than 1:100 .
A single Widal test is of little clinical relevance due to the number of cross reacting infections, including malaria
If no other tests are available, a fourfold increase in the titer (e.g., from 1:40 to 1:160) in the course of the infection, or a conversion from an IgM reaction to an IgG
reaction of at least the same titer, would be consistent with a typhoid infection.
Hope you could understand the things better.
Wish you good health.
