Stool tests are used to help identify parasitic infection in the human gastrointestinal tract. Symptoms of parasitic infection include acute watery diarrhoea, nausea, abdominal pain and cramps, fatigue and weight loss.


The most appropriate test for the diagnosis and treatment of parasites requires the examination of three stool samples collected over three consecutive days.


The parasites commonly detected include Blastocystis hominis, Dientamoeba fragilis, Giardia lamblia, Endomilax nana, Entamoeba histolytica and Cryptosporidium parvum. If any other parasites are detected they will also be reported.


It is particularly relevant to test for parasites these days, especially as many people travel overseas to the tropics and come back with a parasitic infection.


Your health care practitioner (naturopath or general practitioner) can refer you for a parasite test, if needed.
