Hello, Welcome to HCM, I am Dr. Das.
Firstly, the titre means levels of antibody present in our body to the certain antigen.
In case, if typhoid bacteria
, the titre level is very important because, its higher level does not always indicates the presence of salmonella infection
. It depends on the endemicity of salmonella in that particular area.
Here, universally, a titre level of more than 1:200 is thought to be significant. But, otherwise, there is nothing to worry about.
So, according to this, your kid's report is quite satisfactory and it is easy to say that there is no infection. But, still, you have to consult with your local doctor for more appropriate opinion.
