Stool examination for protozoa and helminths by manual method
Laboratory fecal analysis for protozoa and helminths is one of the key methods for diagnosing parasitic infections, which allows to detect various species of intestinal parasites, including eggs, larvae, cysts and vegetative forms. This test is essential to make a diagnosis and monitor the effectiveness of treatment for suspected helminthic or protozoal infections.
What does the test detect?
Manual fecal analysis allows you to detect:
- Eggs and larvae of helminths (worms) such as ascarids, pinworms, ankylostomas, lenticels, and others.
- Cysts and vegetative forms of protozoa (giardia, amoebae, balantidia, etc.).
- Fragments of parasites, indicating the presence of infestation.
Preparation for the test
To get accurate results, it is important to follow several recommendations which are:
- 2-3 days before the delivery exclude the intake of laxatives, fatty foods and drugs that affect the work of the intestine.
- Do not use rectal suppositories or enemas before sampling.
- Collect feces in a sterile container, avoiding urine and other impurities.
- Bring the sample to the laboratory as soon as possible (optimally within 1-2 hours after sampling).
This test is recommended in the following cases:
- Symptoms of intestinal disorders (diarrhea, constipation, abdominal pain, bloating).
- Allergic reactions of unclear origin.
- Itching in the anal area (especially in children).
- General malaise, anemia, weight loss for no apparent reason.
- Contact with infected people or animals.
- Preventive screening (e.g., for workers in childcare centers, food industry).
Advantages of the manual method
- High accuracy due to detailed examination of the sample by a specialist.
- The possibility of detecting various forms of parasites, including rare ones.
- Quick results and the possibility of promptly starting treatment.
