Hi, Thanks for using the HCM.
these tests detects antibodies
bacteria, 1:160 titer and rising titers are more significant than single values in diagnosing typhoid
. your nephew's values are not much significant, these 1:80 values are standards which depends on endemic nature of typhoid disease. better to get test done once again, if values are rising then consult physician for further management.
Hope I have answered your query. If you have any further questions I will be happy to help. Thanks get well soon....
