Parasite laboratory testing

Fortunately, unique technologies have been developed to detect parasitic infections early and start treatment on time.

What tests must be passed to detect worms?

To determine the presence of parasites, one analysis is not always sufficient, because at different developmental stages, worms manifest themselves in their own way.

The main types of analysis are:

  • preventive. Allows timely detection of helminthiasis. This can be done even if there are no typical symptoms. An annual study is recommended.
  • barrier. Reduce the risk of spreading parasites in the population. It is considered mandatory when obtaining medical books.
  • Follow doctor's orders. Analysis was performed if characteristic signs of worm invasion were present: nausea, anal itching, abdominal pain and fatigue.

To accurately determine the presence of worms, you must pass several tests. Also, some of them passed several times.

Fecal analysis for parasites

A stool analysis is the easiest analysis to perform at any regional clinic. The results showed the presence of worm eggs in the feces. The worm's eggs are in it.

Mature individuals can lay thousands of eggs per day. Some of them spread throughout the body through the blood. But, fortunately, most come naturally.

For the analysis to be reliable, it is necessary to:

  • You need to pass up to 3 times. This is because a healthy person has a high risk of swallowing eggs, although this does not mean that he will be infected immediately.
  • Kal is given at 7-day intervals.
  • Feces were taken from various locations.

It is not necessary to collect the material in the morning, and it can be collected in the evening, but the storage time should not exceed one day, and it can be placed in a cool place.

If large numbers of eggs were detected during the study period, another analysis was not required.

Complete blood count to detect worms

Such research has been known to everyone since childhood. Basically, blood is taken from the finger, but sometimes from a vein. Research will soon determine the cause of any disease.

Usually, a person does not suspect that he has worms. Therefore, doctors must be aware of the characteristic symptoms of infection.

This analysis can:

  • Determine the cause of the symptoms.
  • Test the blood for the presence of parasites.
  • Confirm the presence of other pathologies.

There is a misconception that worms only live in the gastrointestinal tract. In fact, many species have penetrated the stomach, then seeped into the bloodstream and spread throughout the body. This is not without serious consequences. Parasites leave traces that doctors will find in the blood.

blood test

Finding information about the study was not easy, and the term itself was unfamiliar to many. In fact, it is a procedure for patients to donate blood for general analysis. Differences in laboratory studies themselves.

Blood test tasks:

  • A measure of the body's immunity to any product.
  • How do you react to them.

Basically, the study is prescribed by a doctor. Hemotest is able to detect parasites that cannot otherwise be detected. This study is considered the most reliable.

Various procedures are performed on blood drawn from patients. It is affected by biological and chemical substances, observe the reaction. This is different and some indicate the presence of worms.

Such tests are quite complex and are not performed in every clinic. The results will be known in 2-5 days. In the presence of parasites, the test will give a positive result.

PCR assay for detection of worms

This diagnosis is considered an accurate and modern research method. PCR analysis can detect the presence of bacteria, intracellular parasites, and viruses. Blood and other body fluids are collected for analysis. If worms are suspected, use feces for research.

Even the detection of some parasite DNA fragments in the biological material indicates worm invasion. PCR analysis is simple and results are known in a few hours. This can be facilitated by using special equipment. With this test, you can get the results you want quickly without doing a lot of extra research.

Unfortunately, not every clinic has such equipment, and the cost of this analysis is quite high.

ELISA blood test to detect worms

blood test for parasites

The most popular and reliable assay available today, experts call it a parasite enzyme immunoassay.

The main purpose of this high-precision laboratory method is to detect antibodies to specific types of parasites in the blood. Immunoglobulins (also called antibodies) are the immune system's natural response to neutralize negative factors.

An enzyme-linked immunosorbent assay (ELISA) shows changes in antibodies in the blood. The study is ideal for identifying parasites.

It is divided into 2 stages:

  • immune system response. Molecular, microbial and cellular elements to be detected can be bound.
  • enzymatic reaction. You can evaluate reaction results visually.

Serological tests

With this laboratory method, infectious diseases and their stages of development can be detected.

This test allows:

  • Determine the patient's immune status. When infected with parasites, the immune system is significantly weakened.
  • Tests the blood for the presence of bacteria that cause a weakened immune system.

By the way, this study was used to determine blood type.

Giardia blood test

This analysis is considered to be of the highest quality. It includes enzyme immunoassays. This analysis determines antibody densities against worms of a given species.

At the time of infection, IgM antibodies appear in the blood, followed by IgA and IgG 2 weeks later.

The results of the study showed that the infection rate of Giardia was as high as 95%.

The analysis was also used to assess the effectiveness of the treatment. If the number of parasites decreases, the recovery method is correctly chosen.


A smear is done to diagnose enterobiasis, which is the presence of enterobiasis in the body.

Scraping is done by:

  • Use a special spatula or a regular cotton swab.
  • Use tape.

The test is considered more effective than conventional stool tests. It can be done independently or in a clinic. You will need to smear the anus with a cotton swab or tape.

Do not wash before surgery. If scraping is done at home, place a spatula or tape (to the glass) in an airtight container and bring to the lab. In order to get more accurate results, the analysis is given several times.

When and where should I be tested for worms?

The analysis of parasites must be carried out in conjunction with the obvious symptoms of a worm invasion: weakness, digestive problems, sudden weight loss and skin diseases. In addition, the presence of worms must be diagnosed in the case of long-term treatment for chronic diseases with no recovery. Often, the pathology is not caused by physiological problems, but by internal parasites.

Anal itching and parasites

The following symptoms must be tested:

  • Anal itching.
  • Dysbiosis.
  • Slobber.
  • Pale complexion.
  • Urinary incontinence.
  • Constipation turns into diarrhea.
  • Abdominal pain in various locations.
  • In women, the menstrual cycle is disrupted.

Give the analysis:

  • at the district clinic.
  • in a medical research laboratory.
  • in a private clinic.

Mainly medical institutions have the necessary equipment and qualified personnel.

What tests are done to detect parasites?

Basically, one assay is enough to detect worms in the body.


  • by Carl.
  • do a shave.

Validation of these assays will take place shortly. In most cases, they are sufficient to identify parasites. Blood tests are sometimes performed, but the process is more complicated, painful and expensive.

Interpretation of the results was performed by the attending physician. Based on these indicators, experts make a final diagnosis and choose a treatment plan.

Prepare the test to detect worms

Note that no special training is required. But there are some guidelines and restrictions.

They are as follows:

  • It needs to be dominated by lightness or rejected outright before passing the analysis.
  • You must stop taking the medicine 3 days before the test. Some components of the drug may distort the results of the study.

Be sure to inform your doctor of existing medical conditions. This also applies to pressure surges, possible fainting and weak blood clotting.

Everyone who cares about their health must check for worms. Helminthiasis is considered a dangerous disease. Worms absorb substances the body needs and release toxins. Therefore, it is desirable to identify the parasites in time before they have time to cause serious harm to health.
