Analysis for dysbiosis: collection rules, interpretation and norms for children and adults

microflora of the human body - a complexAn ecosystem whose equilibrium can be disturbed by a multitude of negative factors. The decrease in the number of beneficial bacteria in relation to the number of microorganisms that are absent in a healthy person is called dysbacteriosis. It is attributed to him the decisive role in the occurrence of a variety of diseases in children's practice. To establish an adequate diagnosis helps such a study as an analysis of dysbiosis.

According to medical research, the general structure of gut microflora comprises more than 450 species of microorganisms. The leading role in maintaining the natural balance is assigned to bacterioids, lactobacilli, and also bifidobacteria. It is they who are able to resist the various aggressors who come from outside.

The formation of dysbacteriosis contributes to the disruption of many functions in the human body. It leads to damage to the structures of the digestive tract, severe hypovitaminosis, various pathologies of allergic nature.

To determine the quantitative and qualitative parameters assigned flora biochemical analysis of feces, further it can be used to determine sensitivity to antibiotics in pathogenic microorganisms.

In what cases assigned study

analysis of the intestinal contents to bacteria overgrowth is assigned in the following cases:

• with persistent course of intestinal pathologies and their immunity to conducted medical measures;
• in case of prolonged courses with systemic drugs - antibiotics, glucocorticoids;
• for severe pathologies of an allergic nature that do not respond to conservative therapy;
• before scheduled surgery in persons with a predisposition to dysbiosis;
• with signs of dysfunction of the intestinal loops caused by chemical intoxication or radiation;
• in the case of a protracted period of rehabilitation after severe intestinal pathologies suffered by the patient.

Analysis of feces for dysbiosis helps to conduct adequate differential diagnosis among a variety of pathologies that have similar clinical manifestations.

culturing stool helps to identify the relationship between the parameters of positive and pathogenic flora in the intestinal loops, as well as on individual indications, their susceptibility to antimicrobial agents.

The main indications for the study to assess the need

fecal bacteria overgrowth in children and adults need only a specialist - on the basis of complaints of the patient, physical examination results, information from other, already carried out diagnostic procedures, for example, or coprogram Hemotest.

main indications for analysis:

• drug identification associated diarrhea;
• reliable establishment of the presence of dysbiosis;
• for optimal selection of therapeutic therapy;
• for assessing the success of conservative therapy of an already established dysbiosis.

How correctly to collect a feces on a dysbacteriosis and where it is possible to hand over the analysis on a dysbacteriosis, the expert will in detail tell during consultation.

How to prepare for the analysis of

How correctly to pass the analysis of a feces on a dysbacteriosis? Specialists emphasize - for obtaining a highly informative result, special preparation is required before the investigation:

1. 3-4 days before the delivery of the biomaterial it is recommended to cancel the intake of laxatives in tablets and candles.
2. Microbiological examination should be performed prior to the initiation of a course of antibiotics or other chemotherapeutic agents.
3. Maximum limit the use of medications that affect the peristalsis of the intestinal structures, as well as the coloration of feces - at least 72 hours before the analysis.
4. Correct the diet - exclude in 3-5 days products that can affect the consistency of stool, their color, the composition of impurities. In babies, the importance is also played by the diet - breastfeeding or the adoption of adapted mixtures: it is recommended to notify the laboratory technician in advance.

Biomaterial obtained for analysis of feces for dysbiosis in children after enema, will be declared unfit. In an adult, in addition to receiving laxatives, setting a purifying enema, a negative result will also be obtained from an x-ray examination using barium.

After deciphering such a result of the analysis of stool for dysbacteriosis, a specialist will recommend its repetition after appropriate preparation.

performing procedures

detailed interview specialist during a consultation, how to take the analysis on a dysbacteriosis child or an adult, what are the contraindications or limitations to the procedure, who spends transcript analysis, the patient receives a referral form to the laboratory, with an indication of his passport details, addressesAnd what is called analysis.

For full-fledged tests for dysbiosis in children and adults, it is preferable to take the morning portion of feces obtained by natural evacuation of the intestine.

The biomaterial is taken with a plastic spoon, mounted in the lid of the container from the pharmacy. It is recommended to avoid getting food items, as well as drops of urine.

There are a lot of questions and doubts in parents about how to take an analysis for a dysbacteriosis in a baby, how to prepare for the procedure.

Enough observe a few simple rules:

• for 3-4 days did not change diet crumbs and most moms, if breast-feeding is done way,
• carefully observe good personal hygiene kid, especially on the day of collection of biological material.

It is preferable to wear gauze diapers from which to collect feces after emptying the intestines of the baby naturally.

The quality of the result - what exactly shows the analysis for dysbiosis - directly depends on the thoroughness of the preparation and collection of feces.

If stool investigation is carried out while taking any antibiotics, it is necessary to specify at the time of the transfer of biological material in the laboratory. How to pass the analysis on a dysbacteriosis in this case, and whether it will be informative, it is necessary to ask in advance at the gastroenterologist.

Interpretation of results

In the case of a second consultation, a detailed analysis of stool analysis in children and adult patients will be given by a specialist. In addition to general characteristics - the color of feces, the presence of mucus or blood in the feces, the concentration and ratio of beneficial, opportunistic and completely pathogenic microorganisms is necessarily interpreted.

Explanation of dysbacteriosis and analysis rules in adults:

• pathogenic intestinal bacteria families, for example, Escherichia lactosonegative should be less than 5 * 10;
• parameters of bifido- and lactobacilli for adequate activity in the intestine should not be less than 10 * 7-10;
• yeast fungi are also present, but their number is minimal - no more than 10 * 3.

Decoding rules and analysis on a dysbacteriosis child:

• bifidoflora presented in infants in a volume of 10 * 11 * 10-10 U / l, opportunistic flora of less than 4 * 10 U / l, Escherichia lactosonegative noShould be;
• in children older than 1 year - bifidoflora in the amount of not less than 10 * 9-10 * 10 U / L, opportunistic flora of less than 10 * 4 U / L, and the bacteria Escherichia lactosonegative dysentery completely absent.

The analysis of the results of analysis for dysbiosis is performed by a gastroenterologist taking into account the recognized norms, characteristic for the patient's age category, predisposing factors, available symptoms, as well as pre-recorded anamnesis. This is how Invitro employees work, assessing the result of feces for dysbiosis.
