See your health care provider. Your health care provider will ask you to submit stool samples. Because E. histolytica can be difficult to diagnose, your health care provider may ask you to submit several stool specimens taken over several days. A blood test is available, but is only recommended if your health care provider thinks that infection has invaded the wall of the intestines or some other organ of the body, such as the liver. A blood test may be positive if you have had an amebic infection in the past.
Several antibiotics are available to treat amebiasis.
Treatment must be prescribed by a physician and may require more than one kind of medication. Drink only bottled water, carbonated water, canned or bottled sodas. Boiling water for 1 minute will kill parasites, bacteria, or viruses that may be present. Food should be cooked thoroughly to kill parasites, bacteria, or viruses that may be present. If you plan to eat raw vegetables that may be contaminated, they should first be washed with a strong detergent soap and then soaked in vinegar for 10-15 minutes.
