Giardia Serology Blood Test

About this test

Giardiasis is a parasitic infection of the upper small intestine. The infection can cause acute or chronic diarrhoea with abdominal discomfort, distension and flatulence. Other common symptoms of giardiasis include abdominal pain, flatulence, bloating, vomiting and weight loss. Symptoms vary from person to person, often depending on the inoculum size, duration of infection, and individual host and parasite factors.

Giardiasis is a common traveler's infection among tourists and business travelers to developing countries, namely the Soviet Union, Mexico, Southeast Asia, and western South America.

Giardia cysts are spread via the faecal-oral route. Cysts may be ingested with contaminated food or water, or acquired from unwashed hands. Infection can be spread from person to person indirectly by water, by faecal-oral contamination with cysts or occasionally by food. Giardia cysts are able to survive in fresh water, and it is the most common cause of epidemic waterborne diarrhoeal disease.

Testing for Giardia can be carried out on blood but, if positive, there is no way of knowing if it is a current or past infection.  Antibodies can be present for up to two years after treatment. Giardia specific antigen may be detected in stool specimens even during an absence of cyst passage or visible signs of trophozoites.
