Laboratory diagnostics and laboratory technicians

Слайд #2

Laboratory diagnostics is a set of methods aimed at analyzing the studied material using various specialized equipment. Laboratory diagnostics are carried out by laboratory technicians.

The most important laboratory diagnosis is in the blood test. The blood test is divided into microbiological culture, biochemical, clinical, serological and PCR methods.

Microbiological culture - one of the stationary methods of cultivating microorganisms on nutrient media, used for cultural diagnostics in medical microbiology, as well as for the study of biochemical and biological properties for various biotechnological purposes.

Biochemical blood analysis - a laboratory diagnostic method that allows you to evaluate the work of internal organs (liver, kidneys, pancreas, gallbladder, etc.), Get information about metabolism (lipids, proteins, carbohydrates), find out the need for trace elements.

Clinical blood test - a medical analysis that allows to assess the hemoglobin content in the red blood system, the number of red blood cells, the color index, the number of leukocytes, platelets. A clinical blood test allows you to consider a leukogram and the rate of erythrocyte sedimentation (ESR).

Serological test or enzyme-linked immunosorbent assay, ELISA - a laboratory immunological method for the qualitative or quantitative determination of various low-molecular compounds, macromolecules, viruses, etc., based on a specific antigen-antibody reaction.

Слайд #7

Blood analysis by PCR (polymerase chain reaction) - a method of molecular biology that allows for a significant increase in small concentrations of certain DNA fragments in biological material. It allows to identify DNA and RNA of pathogenic microorganisms, mutations in the somatic cells of humans, animals, plants and microorganisms and is actively used in infectology, human genetics, reproductology, establishing kinship, etc.

Laboratory diagnostics is used not only in clinics, but also in forensic medical examination. This is a procedural action consisting of conducting research and giving an expert opinion on issues whose resolution requires special knowledge, and which are put before the expert by the court in order to establish the circumstances to be proved in a particular case.
