Bilharzia, also known as Schistosomiasis is a parasitic infection caused by schistosomes or blood flukes found in fresh water in subtropical and tropical regions. Often those infected present no symptoms, but the parasite can remain in the body for many years and cause damage to organs such as the bladder, kidneys and liver. Following a bilharzia infection, the body produces antibodies against the parasite.
What might a low result mean?
A negative result shows there is no evidence of schistosomiasis.
What might a high result mean?
A positive result indicates a schistosomiasis infection but cannot distinguish between a treated infection and an active infection as the antibodies may be present in the blood despite treatment.
