SUBSTANCE: peripheral leukocyte blood values before and after a loading test are measured with the use of the gradual submaximal exercise. The method involves the differentiated recovery of different types of leukocytes from the blood to produce a preparation; a total T-cell (Tt) and active T-cell (Ta) count is determined; a Tt/Ta ratio is derived; mononuclear cells are incubated with granulocytes; a granulocyte-binding lymphocyte index (GLI) is determined in accordance with a granulocyte rosette formation (GRL - contact bound to three granulocytes) to granulocyte contact lymphocytes (GCL - contact bound to one granulocyte) ratio in the preparation; leukocyte indices: lymphocyte index (LI), immune reactivity index (IRI), adaptation index, ("CПHP") are determined; immune functional state adaptation coefficients (K) are derived for each value. Total immune functional body state TIFBS is calculated by formula TIFBS = K"спнр"+Kli+Kiri+Kgli+K"итл" before the exercise - TIFBS1 and after the exercise - TIFBS2. A specific immune functional state coefficient SIFSC is calculated by formula SIFSC = (TIFBS1+TIFBS2)/5, and a level of the immune functional SIFSC reserve is determined. If the SIFSC values are above +1.0, the level of the immune functional reserve is considered to be optimal; the SIFSC values falling within the range of 0 to 1.0 show the satisfactory reserve, whereas the SIFSC values below 0 shows the unsatisfactory reserve.

SUBSTANCE: chronic infectious-inflammatory diseases (CIIDs) are diagnosed. Clinical blood analysis and bacteriological tests are conducted. A sensibilisation index (SI) and an immune responsiveness index (IRI) are calculated; total microbial count per 1 m3 of the working space air is measured, and the total microbial number (TMN) is derived. If the TMN is less than 500 CFU/m3 with no CIIDs diagnosed accompanied by the SI of less than 1.08 standard units and the IRI of less than 13 standard units, the immunoassay is considered to be inadvisable.

Whereas the TMN exceeding 2,500 CFU/m3 with at least two CIIDs accompanied by the SI of 1.4-1.5 standard units and the IRI of 15.8-18.3 standard units, the immunoassay with the second-level tests is thought expedient.

SUBSTANCE: method is based on contacting a membrane test strip with an analysed fluid sample and initiating thereby a motion along the test strip membranes of reagents being parts of the sample or coating the membrane, and forming the immune complexes to be detected in the course of reactions in the membrane pores or on the surface thereof. A distinguishing feature of the presented method for antigen detection is that the test strip is coated additionally within the test sample contact area with a certain amount of specific antibodies, which react to the detected antigen expected to be found in the sample, when a fluid front moves and block a certain number of binding sites. The number of the coating free antibodies is specified so that the low content thereof in the analysed sample being of no diagnostic importance ensures blocking the binding sites completely that prevents the antigen from binding in the analysed area of the test strip and from developing a destructive staining in the analysed area.
EFFECT: presented approach enables reliable diagnosing based on the detection results of the antigens of gastrointestinal disorders, avoiding the achievement of positive test results for the low-antigen samples, which testifies to no development of the disease in an individual.
