Blood test for helicobacter pylori

Disorders in the digestive system and the associated discomfort can be caused by the destructive effects of bacteria that have entered the gastrointestinal tract. To confirm your suspicions, you need to pass a blood test for Helicobacter. The results of the study will be reliable only with proper preparation for the procedure.

Insidious enemy with a Latin name

blood test for helicobacter

Helicobacter pylori is a Gram-negative bacterium that attacks the gastric mucosa, provoking the appearance of irritation, ulceration, and foci of inflammation. The main ways of its transmission are through saliva, mucus and products. This microorganism is not sensitive to gastric juice, it multiplies rapidly and increases gastric secretion, as a result of which various diseases of the digestive system develop. Discomfort will stop if you identify the causative agent of the disease with a blood test for Helicobacter pylori and eliminate.

This diagnostic study is indispensable if a person complains about:

  • pains of varying intensity on an empty stomach or during and after meals;
  • sensation of movement of food along the esophagus at the time of eating and drinking;
  • heartburn and feeling of full stomach;
  • poor digestibility of fat and meat dishes;
  • decreased appetite;
  • nausea and vomiting;
  • bad breath in the absence of pathologies of the teeth and gums;
  • alternation of diarrhea and constipation;
  • deterioration of nails and hair;
  • frequent fungal diseases.

Do not let germs go unnoticed.

Before visiting the manipulation room, you need to go through a preparatory period that lasts at least a day. So that the gastric mucosa is not irritated by extraneous substances and the analysis data are not distorted, it is necessary to refuse:

  • smoking;
  • alcoholic beverages;
  • tea and coffee;
  • greasy food.

8 hours before the procedure, you should completely stop eating.

At the appointed time, the health worker, using a syringe, will take the patient's blood from a vein. Doctors advise to come to the blood sampling with a bottle of mineral water without gas and sandwiches, so that, immediately after unpleasant manipulations, to have a snack or at least refresh yourself with some water.

Decryption of the coveted document

form with the results of the blood test for helicobacter

Having received a form with blood test results for Helicobacter, for which many inconveniences had to endure, people try to understand the indicators right away. In order for such an attempt to succeed, it is necessary, first of all, to understand the essence of the research.

It is well known that the human body reacts to infection with any infection by the production of immunoglobulins - proteins produced by blood cells. They are the ones who fight against harmful microorganisms. Therefore, 1-2 weeks after getting into the stomach of Helicobacter pylori, a type of immunoglobulins will be produced, which counteract this bacterium - LgG, LgM, LgA. If the content of these antibodies in the blood is exceeded, then their "personal enemy" in the body is.

There are no clear values ​​that can be considered the norm in the analysis of blood for Helicobacter pylori. But the following values ​​in IFE units are taken as a basis:

30 for LgG

If the number on the form is less than the specified number, this means that the risk of developing an infection is low or the infection occurred less than 28 days ago. In case of exceeding the norm, we can state:

  • inflammatory process that can provoke gastritis, an ulcer or stomach cancer;
  • carriage (if there are no symptoms of gastrointestinal lesions);
  • overcoming the disease (if the treatment has already been carried out and the indicator is exceeded insignificantly).

30 for LgА

Detection of excessive amounts of this immunoglobulin in the blood

The detection of an excess amount of this immunoglobulin in the blood helps to diagnose:

  • early infection;
  • hidden pathological process;
  • chronic form of the disease.

If there is a figure less than 30 next to LgA, then the bacterium could not be detected due to the initial period of infection or antibacterial therapy is carried out (this type of immunoglobulin disappears before LgG). Also, low values ​​indicate an approaching recovery.

LgM - complete absence

The presence of such antibodies makes it possible to detect the disease within 7-8 days after infection. LgM is not found if:

  • less than a week after contact with contaminated substances;
  • effective antibiotic therapy is carried out;
  • the person is recovering.

In the absence of immunoglobulins LgG, LgM, LgA, established as a result of a blood test for Helicobacter pylori, the decoding is simple: the patient is healthy or infected less than 7 days ago.

Of course, medical knowledge and self-monitoring of health status is commendable. But in order to clarify the diagnosis and prescription of treatment, it is necessary to show the form completed in the laboratory to the doctor.

The appearance of dyspepsia, which is unavoidable with stomach problems, should alert the person. To avoid complications, it is necessary to find out the cause of the disease as early as possible with the help of blood tests for Helicobacter pylori. Exceeding the norm, found when deciphering the results of the study, suggests that well-being will return only after the destruction of the microbe pest. Better to be safe than to deal with severe pathologies of the digestive system!
