What's this test for?

This test is ideal if you're experiencing ongoing diarrhea, stomach cramps, or bloody stools, especially after travel to areas with poor sanitation. It helps identify whether a parasite called Entamoeba histolytica is causing your digestive symptoms. This parasite can also cause liver problems in some cases, so catching it early matters.

What's included in this test?

This test checks for a specific protein marker made by the Entamoeba histolytica parasite in your blood. It's designed to tell the difference between the harmful E. histolytica and a similar but harmless parasite called E. dispar, so you don't get treated unnecessarily for an infection that isn't actually causing problems.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a positive or negative result means. If your result is positive, next steps typically include starting treatment quickly since this parasite can spread to the liver if left unchecked. You can download a standard lab report from your account at any time, and if you're retested later, the trends feature lets you track changes over time.

How can I naturally support gut health during recovery?

Staying well hydrated is important since diarrhea from this infection can drain your body of fluids and electrolytes. Eating simple, easy-to-digest foods like rice, bananas, and broth can help calm your gut while you recover. Probiotic-rich foods like yogurt may help rebuild healthy gut bacteria, but they aren't a substitute for treating the actual infection.

When will I get my results?

Results are generally ready within about 7 days of your sample being tested. You'll get a notification once they're posted to your account so you can log in and review them right away.

Who should consider this test?

This test makes sense for anyone with persistent digestive symptoms like diarrhea, cramping, or blood in the stool, particularly after travel to regions where this parasite is common. It's also useful for people living in or recently returning from areas with limited access to clean water or sanitation. If you've been in close contact with someone diagnosed with this infection, testing is a smart precaution.

What symptoms indicate I may need this test?

Common symptoms include watery or bloody diarrhea, stomach pain, cramping, and unexplained weight loss. Some people also experience fatigue or mild fever. In more serious cases, pain in the upper right side of the abdomen can signal the infection has spread to the liver.

What is Entamoeba histolytica and why does it matter?

Entamoeba histolytica is a microscopic parasite that lives in the intestines and spreads through contaminated food or water. While many people carry a similar, harmless parasite without any issues, E. histolytica can cause serious illness including intestinal inflammation and liver abscesses. Identifying which one you have matters because treatment is only needed for the harmful type.

What causes an Entamoeba histolytica infection?

You typically get infected by swallowing the parasite's cysts through contaminated food, water, or surfaces, or through contact with infected stool. This is more common in areas with poor sanitation or when traveling to developing countries. Poor handwashing habits after using the bathroom can also spread the infection between people.

What should I do if my results are positive?

A positive result means the harmful parasite was found, and treatment is usually needed to clear it and prevent complications like liver abscesses. Drink plenty of fluids to stay hydrated and avoid preparing food for others until you've been treated. If you develop severe abdominal pain, high fever, or signs of dehydration, seek medical care right away.
