antibodies to amoebiasis An Igg test is used to diagnose amoebiasis, a parasitic condition of the intestines brought on by the bacterium Entamoeba histolytica. This illness frequently shows no signs. However, it can occasionally result in stomach and stomach cramps, liver or stomach infections, diarrhoea, increased urgency and frequency of stools, loose and foul-smelling faeces, and gas. A few days to a few months after exposure, the symptoms may show up, but often between two to four weeks. This examination aids in finding anti-amoebic antibodies. This disease might be treated with an early diagnosis and the right drugs.
