IS IT TRUE THAT I HAD TYPHOID [/INST] Hi, Welcome to Chat Doctor. Your liters of Tidal are showing positive for typhoid. In Tidal test, antibodies against typhoid bacilli are detected by an agglutination test against two main antigens of the bacteria O and H. If antibody tier for O is 1:80 and above and H above 1:200 is significant. I suggest you get appropriate antibiotics for the fever and get dietary advice from your treating doctor. Thanks. </s>
