Hello and welcome to HCM,
The test that you have performed is Widal test which is done to detect typhoid fever.
For diagnosis of typhoid fever antibody titers for Salmonella O and H antigens & Salmonella paratyphi O and H antigens is done.
The test is interpreted as reactive when the antibody titers are above 1:80.
However, in your test report the titers are only 1:40 and thus negative.
Kindly, consult your primary healthcare provider for clinical assessment.
Thanks and take care
