Widal test results are listed: AH: 1/320 (+), BH: (-)
Hello Yunita, thank you for asking at HealthReplies.com.
Widal examination / test is an examination that is still quite commonly used in Indonesia to find out whether a person is infected with typhus or paratifus, where through this test, an assessment of the antibody status / immunity of a person against the bacteria that causes typhus and paratitis (paratypes A, B, C ).
The antibodies examined in this test are the body's antibodies to one of the bacterial components called O and H antigens and the results of the test are stated in positive / negative and how many dilution rates are obtained, where the dilution rate starts from 1/20 to 1/320.
The dilution rate that is used as the limit for someone positive for typhus or paratypic infection is 1/160, so if the number reaches 1/320 as the results you write down, it can be said that the result is positive and the person most likely is infected with typhus or paratifus.
For the results you write down, AH is a symbol to show the body's antibody examination against H antigens from paratypical A bacteria, where the dilution result is 1/320 so it can be said that the result is positive and the person is most likely to have paratypical infection A.
Whereas for BH, it is a symbol for antibody examination against H antigens from bacterial B paratifus and no antibodies are found, so it is stated as negative.
Based on these results, it is strongly recommended to consult the results of the examination with a doctor who recommends conducting a widal examination to obtain further appropriate therapy.
I hope this helps.
