LABORATORY

From Big Medical Encyclopedia

LABORATORY (late lat. laboratorium, from armor. laborare to work, process) — institution, department of establishment, the enterprise for conducting pilot studies, check tests, the analysis of products and other works, and also the special room intended for their performance. L. appeared during origin of scientific research as specially equipped rooms for chemical experiences. After laboratory began to call any room equipped for carrying out researches in any branch of science and technicians and also for carrying out educational experiences.

In Russia the first L. for chemical microscopic examinations appeared in 1858 in St. Petersburg in Medicochirurgical academy. The first dignity. L. arose at the initiative of I. I. Molleson, N. A. Zolotavin, I. I. Mechnikov, N. F. Gamalei in 70 — the 80th there are 19 century. In 1914 in the country existed 61 sanitary and hygienic and apprx. 100 clinicodiagnostic L. After Great October socialist revolution in the course of creation and development of the Soviet health care and a dignity. - epid. services number L. considerably increased, and the sphere of their activity extended. Promptly the number of clinicodiagnostic L grew., what allowed to provide the vast majority in post-war years to lay down. - professional, institutions in the cities and the most part — in the village in the L.

Medical research L. as independent establishment can directly submit to the USSR Academy of Medical Sciences (e.g., Laboratory on organ transplantation and fabrics of the USSR Academy of Medical Sciences) or M3 of the USSR, min.-vu health care of the federal republic. In research in-those L. is the structural division which is carrying out the researches directed to the solution of a separate problem (e.g., L. synthesis of protein etc.) or the researches based on certain methods (e.g., spectroscopic L.). In higher educational institutions the central research L are created. (for the help to departments in scientific research), problem L. (for the solution of especially important scientific problems), industry L. (for researches of applied character). In to lay down. - professional, institutions (-tsakh, policlinics, clinics, sanatoria) there are clinicodiagnostic L., sometimes with specialized departments (biochemical, serological, etc.), radiological laboratories (see), tsitol. L., being a part pathoanatomical department (see), on SES — a dignity. - chemical, bacterial., virusol. L. (see. Bacteriological laboratory , Virologic laboratory ), parazitol. L., in system court. - medical examinations — court. - medical and court. - chemical.

L. V L. work specialists with the higher and secondary medical education (see. Laboratory assistant ), technical and support personnel. Regular standards of L. to lay down. - professional, and a dignity. - epid, institutions, requirements to qualification of their employees are regulated by M3 of the USSR. Functions of employees are defined by the instructions following from the tasks facing L.

Rooms of L. are divided into the main and auxiliary. In the main rooms jobs for performance of researches are placed, laboratory engineering (see) and the equipment, in auxiliary — registration, preparation and pretreatment of material is made for a research, washing and drying laboratory glassware (see), preparation of reactants, mediums. In large L. certain rooms or jobs for various groups of analyses are allocated. In a row L. boxes for work with microorganisms are equipped, radiation protection of personnel by radoactive radiations, etc. is provided. The structure, the sizes and the equipment of rooms depend on the tasks solved in L., its state also shall provide the most rational placement of jobs taking into account requirements of occupational health and the accident prevention of personnel. V L. positive-pressure ventilation with sufficient air exchange, including for separate jobs shall be equipped (hoods), sufficient lighting (the general and local), power supply taking into account the power of all electric devices, plumbing and sanitary is provided.

As in L. heating and other electric devices, flammable solvents and reactants, L are widely used. shall be equipped with fire-prevention devices (the fire-prevention alarm system, means of automatic fire extinguishing) and manual means of suppression of fire (foam, carbon dioxide fire extinguishers, asbestos blankets, sand); the personnel shall follow strictly rules of fire safety, be able to use means of fire extinguishing, to know ways of evacuation of people and property from the room.

The clinical diagnostic laboratory would be department, policlinics, a clinic and others to lay down. - professional, institutions; it will be organized according to their structure. Type and power of L. depend on a profile and the power of establishment, to-rogo it is a part. L are most widespread. the general type, servicing multi-profile-tsu, policlinic; they make an all-wedge., gematol., biochemical, tsitol., mikrobiol., serol, researches, etc. In specialized to lay down. - professional, institutions (clinics,-tsakh, hospitals, sanatoria, clinics for women, maternity homes etc.) L. carry out the general and special a lab. the researches corresponding to a profile of establishment.

Content of activity of clinicodiagnostic L. is defined by the «Nomenclature of main types of laboratory analyses» approved by M3 of the USSR. In 1946 the nomenclature contained the 115th lab. tests, in 1970 — St. 400. Draft of the nomenclature lab. researches, developed by Committee of WHO experts, contains St. 700 names of analyses.

The smallest on number a lab. tests the obligatory minimum a lab is. researches for local BCs and medical out-patient clinics (see. Laboratory business ). It provides the following.
