Parasites are organisms that live in or on other organisms, in this case the intestines. Parasites can cause a variety of symptoms, such as abdominal pain, diarrhea, nausea, and fatigue. In order to determine if there are parasites in the intestines, a doctor will typically order laboratory tests such as a stool sample, blood test, or imaging test.
Stool Sample
A stool sample is a commonly used test to detect the presence of parasites in the intestines. In a stool sample, a sample of the person’s feces is examined under a microscope for the presence of any parasites or their eggs. The stool sample can also be tested for the presence of certain chemicals that may indicate the presence of parasites.
Blood Test
A blood test can also be used to detect the presence of parasites in the intestines. The blood test looks for antibodies that the body produces in response to the presence of parasites.
Imaging Tests
Imaging tests such as an X-ray, CT scan, or ultrasound can be used to detect the presence of parasites in the intestines. These tests can provide a detailed image of the intestines, allowing the doctor to see the parasites and diagnose the condition.
