Correct diagnosis is always the first step towards curing a disease. The analysis of feces for eggs, worms and protozoa is often prescribed for both children and adult patients, because the study of this biomaterial in most cases gives an accurate answer about the presence of one or another type of parasite in the human body. Learn important guidelines to follow when making this diagnosis.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

How to get tested for helminths

The results of this simple and painless examination are very informative for the doctor, who, according to the complaints of the patient who applied for the appointment, suspected helminthiasis in him.

Therapists prescribe the patient to check feces for worm eggs and protozoa in a variety of cases, because the symptoms of parasite infection can manifest themselves in a very diverse way.

So, a person should be tested for worms if he has the following signs of infection:

  • loss of appetite;
  • frequent bloating, upset stomach, constipation;
  • rash on the skin of an allergic nature, its dryness;
  • increased body temperature;
  • headaches;
  • general fatigue and decreased immunity;
  • a child with a worm may grind his teeth while sleeping.

Testing for helminths by examining feces is an effective way to identify parasites that live in the intestines. Having received information about the type of worms with which a person has become infected, the doctor can prescribe the necessary medications. Rapidly taken measures to treat helminthiasis will not only stop the disease, but also prevent the introduction of parasites with blood flow into other organs of the body.

Indications for the analysis of feces for eggs, worms and protozoa

Unfortunately, most people think that the only noticeable sign of a worm infection is burning and redness of the skin around the anus (enterobiasis). Meanwhile, such itching occurs only if the helminths settle in the intestines, and they affect different parts of the body.

And the symptoms in each case are different.

  • Worms often target the eyes. Thanks to the many capillaries, there is a good blood supply here, which means it is an ideal feeding trough. Symptoms - yellowing of the vitreous body of the eye, as well as the skin around it;
  • Brain. There are also many blood vessels here, however, the blood-brain barrier prevents penetration. The main symptom of infection is unreasonable irritability;
  • The liver serves as the protection of our body from all kinds of poisons, and when worms enter the body, it begins to increase in size and hurt;
  • If the muscles are damaged, there will be a feeling of aches in them and in the joints. If we are talking about the muscles of the heart, then the pulse will increase;
  • The skin is also a desirable habitat for many helminths. Infection symptoms: red rash, tingling or numbness.
  • In case of damage to the gastrointestinal tract (GIT), in addition to the already mentioned enterobiasis, the following are characteristic: sudden weight loss, pale skin, nausea, poor resistance to infections, loss of appetite, or vice versa, constant hunger, shortness of breath, frequent dermatitis and other types of allergies, heaviness in the right side, migraines, lethargy, bitterness in the mouth, insomnia, abdominal pain, dizziness, constipation or diarrhea.

Therefore, you should be on your guard if you or someone from your household: recently returned from a long stay in a closed team, did not follow the rules of hygiene for a long time, ate meat or fish without sufficient heat treatment, worked with pets.

How to prepare

The analysis of feces for worms in the general case does not require any special preparation measures. But, if the patient is taking potent drugs, including antibiotics, then the analysis of feces for protozoa is prescribed no earlier than three days from the last dose, so that the drug does not distort the results of the study.

Also, procedures related to the gastrointestinal tract (gastroscopy, colonoscopy) are stopped. Preparation for the analysis of feces for worms also provides for dietary restrictions.

For three to four days exclude:

  • White rice;
  • Mushrooms;
  • Meat;
  • Fresh vegetables and fruits;
  • Any sorbents;
  • Kvass, juices;
  • Nuts;
  • All kinds of by-products containing iron, causing upset stools or increasing gas production.

It is also worth refraining from eating beets and berries, so they can color the feces, arousing suspicion of occult blood (in patients with hemorrhoids, bleeding gums, or those with cracks in the anus, such an analysis is not taken at all).

Regarding hygiene procedures, it is recommended not to brush your teeth or wash yourself the day before. Defecation should take place naturally, without the use of a laxative. Drink plenty of water, move (but in moderation, without fanaticism). This will allow you to relax properly.

The procedure for collecting feces to identify eggs of worms

The answer to the question of how to correctly hand over feces for analysis to an adult is simple. You take a clean, dry plastic or glass container (you can buy a special container). No sterilization required. And you collect feces in the amount of two teaspoons.

Analysis kit
Analysis kit

You need to take the material from three parts: side, central and top. The fence should be done with a disposable spoon, since taking with a cotton swab, and even more so with a twig, you can bring in fibers, infections or even parasites, which will distort the examination result. Be careful that urine does not mix with the stool.

However, due to the prevalence of this method, almost every adult already knows how to collect feces for analysis. As for the required volume of feces, the amount of feces required for analysis is written in the previous paragraph. The only exception is the case of loose stools, then a volume of at least five milliliters is needed.

What helminthiasis can be diagnosed by examining feces

The most common are 3 groups of parasites that can be detected by examining stool:

  1. roundworms (nematodes): roundworms, whipworms, nekator, pinworms, duodenal crooked heads;
  2. flukes (trematodes): schistosomes, hepatic and feline flukes;
  3. tapeworms (cestodes): bovine tapeworm, pork tapeworm, wide tapeworm.

Let's dwell on the features of the diagnosis of each helminthiasis.

Ascariasis. Helminth eggs have a small size of 50-70 microns, oval in shape and are detected by microscopic examination of a stool sample. However, the absence of Acarid eggs in feces does not exclude this diagnosis: they can be found in feces only 90 days after infection, provided that adult females are parasitized

Chronic ascariasis
Chronic ascariasis

Trichocephalosis. Whipworm eggs, only 20-50 microns in size, in the form of a brown barrel, can be detected only by microscopy of feces, but not in all cases - the infection should be quite intense. Therefore, the diagnosis is carried out several times

  • Nonatorosis. Helminth eggs appear in feces 2 months after infection, and have a size of 30-60 microns.
  • Enterobiasis. Pinworm eggs are oval, colorless, flattened on one side, 20-60 microns in size. Females lay a huge number of eggs (5-15 thousand), but catching them in feces is problematic, since females crawl out of the intestines to the anus to lay eggs. Therefore, when examining for enterobiasis and eggs, worms found in the perianal imprint, and living individuals, visually visible in the feces, are of greater diagnostic value than the study of feces only for helminth eggs.

Ankylostomiasis. Kryvologovka eggs are oval, colorless, transparent, 30-70 microns, have a thin smooth shell, 2-8 crushing balls are found in fresh feces. But it is rather difficult to identify them, only during the laying of eggs by the female (up to 10 thousand), when they, together with undigested food, go outside


Schistosomiasis. The eggs are oval in shape, the cap is missing. There is a small spike on the lateral surface. Egg size - 70-110 microns. Found in feces after 1-3 months. after infection


Opisthorchiasis. The eggs of the liver fluke have a regular oval shape, size 70-145 microns, a smooth shell with a small lid. The flat tubercle is visible at the opposite pole, in the cavity of the egg there are uniform yolk cells. Found in feces 30-40 days after infection, the number of eggs per gram is taken into account. feces to set the degree of disease. The eggs of the feline fluke are very small, 10-20 microns, oval, with a thin shell, tapering more towards the pole, with a lid. There is a spine at the opposite pole. There is a fine-grained content

  • Teniarinhoz, teniasis. To diagnose bovine and pork tapeworm, feces are examined for eggs, as well as fragments of the worm's body. The eggs are round, 20-40 microns, have 2 filamentous processes, inside - an oncosphere embryo. Differential diagnostics is carried out, since the eggs of the two types of tapeworms are similar to each other.
  • Diphyllobothriasis. Ribbon eggs are wide, 45-70 microns, oval, yellow or brown. There is a lid at one pole, a tubercle at the other. The inside of the egg contains coarse-grained contents.

In most cases, additional studies and diagnostic methods are prescribed to confirm the diagnosis: blood ELISA, hemoscanning, retroromanoscopy, colonoscopy, examination of duodenal juice, coproovoscopy - detection of segments and proglottids in feces and perianal region, and others.

Features of collecting feces in infants

To collect an analysis from a baby, mother and child prepare together. Mom needs to know important points:

  • Do not change food:

    • during breastfeeding, this concerns the mother;
    • if the child eats mixtures, then they cannot be changed or new ones added 3-4 days before the biomaterial is checked for the presence of worm eggs.
  • Stop using medicines, laxatives, "Smekty".
  • You can not do thermal procedures, enemas.

It is better to buy a special container at the pharmacy for testing. It is sold with a spoon, which simplifies the collection process. It is quite difficult to catch the moment of emptying, because the mother is obliged to constantly monitor the child. When defecating, collect the biomass with a spatula from different sides, or, if it is very liquid, quickly drain it into a container until it is absorbed into the diaper.

You can use a urine collector by attaching it to the child's bottom and wearing a diaper on top. Often, the infant defecates immediately after feeding. In this case, you need to undress it and spread a disinfected oilcloth.

If the child has constipation, then you can help him: a light massage of the tummy with circular movements of the hand has a positive effect. As a last resort, you can use a gas pipe. It is lubricated with petroleum jelly and inserted into the anus by 0.5 cm.

When children are tested for the presence of worms, it is correct to take the analysis to the laboratory within 2 hours after emptying. For this, 5 g of material is enough. If the check is done for enterobiasis with the help of scraping, then the process must be approached differently: the child cannot be washed away.

The collection takes place in the morning, without getting out of bed, with the help of a cotton swab held around the anus - this is where the pinworm eggs are collected. Delivery of the analysis to the laboratory is carried out within an hour.

How much is valid?

The test period for worms is 10 days. However, if the examination showed the absence of helminths, then it is too early to rejoice. To confirm this result, the analysis is submitted several times after a certain time. A person is not sick with helminthiasis if no worm eggs were found in the feces in any analysis.

Deciphering the analysis of feces for worm eggs

The analysis for helminths and protozoan cysts is a complex procedure, the result of which depends on the degree of invasion. It makes it possible to detect larvae and eggs in the feces, but not the worms themselves. In the case of a severe lesion, the parasite will be detected, however, to establish the correct diagnosis, the patient is prescribed directions for several tests. The patient will need to donate feces to the ovule 3 times.

This is done either every day, or with a break of 1-2 days. Helminthiasis is refuted if the eggs of the worm were not found in the feces, that is, in front of all types of parasites there is a mark "negative". If the analysis of feces for worms is positive, it means that the patient is diagnosed with invasion.
