Giardiasis is one of the most common forms of parasite infestation. Giardia is the simplest microorganism that infects the intestines and parasitizes in the human body for a long time, which negatively affects the general state of health.

In the first stages, infection is detected by chance, since it is not accompanied by severe symptoms. A blood test for Giardia is the most reliable way to find out about an invasion.

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 >>>

Blood test for lamblia in children and adults

At the first signs of infection, you should consult a doctor. During the examination, he assesses the clinical picture, chooses the best way to diagnose the disease.

The indications for a blood test are:

  • attacks of nausea, vomiting;
  • prolonged stool disturbances;
  • flatulence, pain, bloating;
  • general tiredness;
  • unstable psycho-emotional state;
  • the development of allergic reactions in the form of a rash;
  • changes in the structure of feces.

The first signs of invasion may appear only a month after infection. An analysis during this period may already indicate the defeat of the body by the parasite. However, due to the absence of symptoms, a person does not go to a medical institution, which significantly complicates the diagnostic process.

How to take

Having received a referral for a blood test for lamblia, the patient is sent to the laboratory, where blood is taken in the amount necessary for the study.

Various factors, such as smoking, can affect the test results. The analysis requires venous blood. The fence is carried out in the laboratory.

A week before the tests, you need to exclude from the diet:

  • smoked, sweet, fried, salty and spicy foods;
  • you can not drink tea, coffee, any carbonated drinks and alcohol.

Before taking blood, it is better to warn the laboratory assistant about possible negative reactions to the analysis, for example, a possible loss of consciousness.

Decoding the results

OPD below 0.85 OPD greater than 1 OPd 0.85-1
It is considered the norm - there are no parasites in the body, no treatment is required. A positive result is a sign of a chronic or exacerbated course of the disease, therapy is required. Questionable result. It is necessary to retest to confirm the diagnosis. If the results are identical, the person is healthy.

Blood test for antibodies to lamblia

ELISA of blood involves the study of the antigen-antibody reaction. For analysis, blood is also taken from a vein, it is mixed with lamblia antigens. During the reaction, it is possible to determine the presence of antibodies (IgG, IgM, IgA), which are produced to fight the parasite.

The analysis is highly accurate (about 90%). The results will be presented in the form of the following scheme:

IgM +, IgG-, IgA- No antibodies
IgM-, IgG +, IgA- The presence of developed immunity to the pathogen
IgM +, IgG - / +, IgA - / + Exacerbation of invasion
IgM +, IgG +, IgA + Chronic infection
IgM- Recovery

If antibodies with an IgG marker are found in the blood, infection cannot be asserted. Immunity will produce these antibodies for some time (1-6 months) after recovery, they can be found in the blood.

PCR analysis for lamblia

Polymerase chain reaction (PCR) - examination of feces or venous blood. This analysis can be prescribed in combination with an ELISA blood test, which significantly increases the reliability of the results. PCR is aimed at identifying fragments of the parasite's DNA and is used to study the dynamics of treatment.

The patient needs to collect the morning stool. This should be done before hygiene procedures in the morning after waking up. To eliminate the possibility of mixing urine and faeces, the bladder must be emptied beforehand.

The feces are placed in a sterile container, closed and sent to the laboratory for research (within 8 hours). The analysis does not require a special diet.

Preparation for analyzes

A week before blood sampling, you need to follow a diet enriched with light, quickly digestible foods.

On the day of blood sampling, the patient is forbidden to eat and smoke, you can only drink water without gas - every factor can affect the final result.

It is recommended to stop taking medications a few days before the examinations, if this is not possible, you need to notify your doctor about this. This will allow a reliable diagnosis to be made.

You need to enter the office without haste - increased physical activity provokes the release of certain substances into the blood, which can distort the test results.

Price and where to rent

The cost is influenced by the region where the laboratory is located and the type of blood test for Giardia. In the Invitro laboratory, the cost of testing for Ig antibodies with the M, A, G marker is 115 UAH.

The diagnosis of giardiasis is complicated by an asymptomatic course in the early stages of invasion. Various diagnostic methods are used to detect the parasite. The most reliable is a blood test. It is not recommended to start treatment on your own without going through a doctor's examination. Self-medication can cause serious complications.
