Parasites such as giardia have a high survival rate. They can live in various environments, but prefer the human body. Usually parasites are found in the intestines. A favorite place is the mucous membrane of the small intestine. As a result of their vital activity, the patient has a digestive disorder.

In most cases, children suffer from giardiasis, whose immunity is not yet strong enough. If treatment is started too late, the parasites can cause significant health damage. Timely diagnosis and appropriate treatment is a guarantee that the body will quickly cope with the disease.

People suffering from intestinal pain may not even suspect that their body has become a haven for parasites. They are also not familiar with the tests that help identify lamblia. Medical specialists distinguish a study of blood and feces.

A blood test for helminthiasis and giardiasis is not only modern, but also has a greater percentage of reliability.

Under what circumstances is it necessary to take tests

Giardiasis is a disease that is accompanied by various symptoms. There are times when the doctor is unable to identify the source of their occurrence. Experienced doctors are in no hurry to make a final diagnosis until the patient donates blood for Giardia. After studying the results of the analysis, conclusions can already be drawn.

It is recommended to contact the polyclinic in the following cases:

  • upset stomach with periodic regularity;
  • bouts of nausea;
  • rumbling in the stomach and any similar discomfort;
  • with flatulence;
  • pain in the stomach;
  • pain in the large intestine;
  • frequent constipation;
  • diarrhea.

It is possible to detect parasites by blood only if 1 to 3 weeks have passed since the start of infection. At first, helminths manage not to show their presence in the host's body, so the patient is unaware of their presence in his body.

Often, the first signs of the disease do not cause any suspicion, and people try to prescribe treatment for themselves. It is categorically impossible to do this: there have not yet been such cases when self-medication gave a positive result. It makes sense to see a doctor - he will tell you what tests need to be done, and as a result of examination and study of the results, he will prescribe treatment.

More about giardiasis and blood tests

Worms can be detected in the body by examining feces and blood. If the diagnosis is not successful, a bile test may be required. To date, the most truthful is the blood test for antibodies to lamblia using the ELISA method. As a result, it detects special antibodies produced by the body after infection with lamblia.

Any specialist will confirm that no analysis can give one hundred percent result. As a rule, it is prescribed in parallel with other diagnostics. Why is this happening? Unfortunately, the body does not immediately start producing antibodies to parasites, so they can be in the body of the chosen host for a long time.

That is why it is not possible to accurately determine the presence of worms in the patient's body. However, the analysis will be useful if you need to clarify the result, that is, donate blood for giardiasis. A thorough examination of the stool helps to accurately indicate whether there is giardia in the body. In other cases, the detection of antibodies in the blood is the main confirmation of a diagnosis already made.

How to prepare for a blood draw

Any test delivery begins with proper preparation. As a rule, tests are taken in the morning before eating. In this case, a person should not eat food 10 hours before delivery. Alcohol, tea, juices, or coffee can interfere with the detection of parasites in the blood. You can drink plain water from drinks.

What does the obtained result say?

Deciphering the blood test allows you to establish the presence of antibodies to lamblia. Testing systems can detect antibody classes such as IgA, IgM and IgG. By decoding the ready-made data, the doctor is ready to establish the final diagnosis.

The presence of IgG antibodies in the body indicates that the fight against parasites is in full swing. The amount of antibodies can remain high even after the patient has completely recovered. A couple of months after infection, their blood level decreases, and after 5-6 months, complete disappearance is observed.

IgM antibodies appear in the body 12 days after the onset of infection. If the doctor confirms their presence, then the person is infected. Only the attending physician can correctly decipher the resulting analysis, so you should not do this on your own.

In medical practice, there have been cases when antibodies remained in the body throughout a person's life. At the same time, medical research showed that he was completely healthy and did not need treatment. Based on the fact that antibodies can remain in the body for a long time, the test result should not be considered accurate. This is not the main indicator of the presence of helminths in the human body.

Analysis confirmed the presence of lamblia

If a blood test for giardiasis turned out to be positive, this fact must be taken into account. First of all, you should reconsider your diet - perhaps refuse any food. In parallel with the main treatment, doctors recommend adhering to a special diet. Do not eat dairy products and fatty foods.

You should also pay special attention to personal and general hygiene. A person should always monitor the condition of their nails and wash their hands before eating. Cleansing the palms after visiting crowded places and the toilet will minimize the growth of infection. This behavior will help maintain health not only for the patient, but also for his loved ones.

Hygiene and diet are only additional guidelines. Only a doctor has the right to prescribe the main treatment. In this case, the person should not self-medicate, as this can aggravate the situation.

If a person has undergone treatment and has done everything the doctor said, you can go for a second test. Donating blood will help check the result of drug therapy

Giardia in any family member

If parasites have been found in one of the family members, you should proceed in the following way.

  1. To begin with, all family members are tested for giardiasis.
  2. As a result of a positive analysis, the doctor prescribes appropriate treatment.
  3. Even a healthy person may need treatment as a preventive measure.

The possibility of re-infection is not excluded, so you should be very careful. The whole family needs to analyze the level of cleanliness in the house where they live. Maintaining cleanliness and personal hygiene will help eliminate the possibility of infection.

conclusions

Knowing how to get tested to detect parasites in the body, you can heal much faster. Establishing the correct diagnosis guarantees a successful cure. But success lies not only in the right medicines - you can improve your health by eating right and cleaning your personal home regularly. In this case, nothing will threaten human health.
