ESR is 34mm. plc help me
[|AI|]  Hello,TIDAL test is not a diagnostic test in typhoid but during the 2nd week of fever raising title of antigen from 1:80 to 1:160 to 1:320 helps to make the diagnosis. Blood culture in the 1st week is more valid to make the diagnosis. There are many conditions which can lead to mild splenomegaly and hepatomegaly, typhoid fever may also cause mild splenomegaly, but hepatomegaly is very rare in typhoid. ESR will be raised whenever there IA active infection in the body. You require physical examination to confirm the USG report. Thank you.
