Detection of intestinal parasites and their eggs

• The stool is delivered to the laboratory for examination within 2 hours of collection. If the delivery time exceeds 2 hours, it is necessary to use containers with a preservative for transporting the material.
• The container with feces is tightly closed with a lid, packed in a clean disposable bag and delivered to the laboratory.
• Stools should not be submitted for testing after an enema, suppository insertion, or castor oil administration. Stools for testing should not contain foreign substances, such as urine.
• In newborn babies, feces are collected from the diaper or nappy immediately after defecation.

Gastrointestinal diseases are one of the most common medical problems in the world. They can be caused by various factors, among which intestinal parasites occupy an important place. These microorganisms can cause serious diseases and pose a threat to human health. For successful treatment, it is necessary to detect the presence of parasites and their eggs in the gastrointestinal tract in a timely manner. In this article, we will consider methods for diagnosing intestinal parasites and their eggs.

1. Clinical symptoms and complaints

The most common symptoms and complaints that may indicate the presence of intestinal parasites are:

• Diarrhea or constipation.
• Abdominal pain.
• Decreased appetite and weight.
• Flatulence and feeling of fullness.
• Constant fatigue and weakness.
• General malaise and various allergic reactions.

These symptoms can be caused by various factors, so it is important to conduct additional diagnostics to accurately determine the cause.

2. Laboratory studies of feces

One method of detecting intestinal parasites is a stool test. A laboratory examines a sample of the patient's stool for the presence of parasites or their eggs. This is done using a microscope and special dyes that help to highlight the structures of the parasites. Some of the most common parasites that can be found in stool are roundworms, amoebas, and Giardia.

3. Blood tests

Another diagnostic method is a blood test. The blood may contain antibodies that the body produces in response to the presence of parasites. These antibodies can be detected in the patient's blood. In addition, blood tests can determine the content of eosinophils, which usually increase with parasite invasion.

4. Gastroscopy and colonoscopy

In cases where other diagnostic methods do not provide a clear picture or there are suspicions of serious lesions of the gastrointestinal tract, the doctor may prescribe a gastroscopy or colonoscopy. These procedures allow you to examine the walls of the gastrointestinal tract and take biopsy samples for further examination.

5. Molecular methods

Modern molecular biology allows the detection of intestinal parasites using polymerase chain reaction (PCR). This method is very sensitive and can detect parasites even when their numbers are too small to be detected by microscopy.

Detection of intestinal parasites and their eggs is an important step in the diagnosis of gastrointestinal diseases. Accurate and rapid diagnosis allows you to start treatment on time and prevent further complications. If you observe symptoms indicating a possible parasite infestation, consult a doctor for examination and treatment.

Maintaining gastrointestinal health is an important component of overall well-being, and timely diagnosis and treatment play a key role in achieving this goal.
