I'm trying to understand these test results better. It says "Salmonella typhi O TO Reactive up to Titre 140" and "Salmonella typhi H TH Reactive up to Titre 1160." Then there's "Salmonella paratyphi A H AH Reactive up to Titre 180," but "Salmonella paratyphi B H BH Non Reactive." Should I be worried about these numbers? What's the difference between my typhi and paratyphi results? Any advice on what these mean for my health? I'm kind of concerned about what I should do next.
