A medical laboratory is a placewhere tests are done on clinical specimens and samples in order to get information about the health of a patient as pertaining to the diagnosis, treatment, and prevention of disease • Laboratory Services include testing of materials, tissues or fluids obtained from a patient or clinical studies to determine the cause and nature of disease
Haematology • Histopathology • Cytology • Routine Pathology • Bacteriology • Mycobacteriology • Virology • Mycology • Parasitology • Immunology • Serology • Biochemical analysis • Hormonal assays
What are Laboratory Services all about? Laboratory Services play a critical role in the detection, diagnosis and treatment of disease. Samples are collected and examination and analysis of body fluids, tissue and cells are carried out. Main services are: • To Perform diagnostic tests • To Identify organisms, like E-coli bacteria • To Count and classify blood cells to identify infection or disease • To Operate complex diagnostic equipment • To Perform immunological tests to check for antibodies • To Type and cross-match blood samples for transfusions • To Analyze DNA
Services we provide.. Microbiology Parasitology Virology Haematology Coagulation Clinical Biochemistry Toxicology Immunohaematology/Blood bank
Urinalysis Histopathology Cytopathology Electron microscopy Genetics Cytogenetics Surgical pathology Immunology/Serology
Planning for equipments • Basic instruments and equipments should be made available • All vital equipment should be in duplicate or have an alternative arrangement • Selecting the best instrument for the laboratory is a very important part of equipment management
Following element should be considered during management program in laboratory: 1) Selection and purchasing 2) Installation 3) Calibration and performance evaluation 4) Maintenance 5) Troubleshooting 6) Service and repair 7) Retiring and disposing of equipment
Lab equipments Basic equipments for all types of routine investigations are: 1) Colorimeter/Photoelectric colorimeter: Its a device that measures the absorbance of particular wavelengths of light by a specific solution 2) Centrifuge: Is a piece of equipment, generally driven by an electric motor that puts an object in rotation around a fixed axis, causing denser substances to separate and by which lighter objects will tend to move on top 3) Water Bath:A device for regulating the temperature of anything subjected to heat, by surrounding the vessel containing it with another vessel containing water which can be kept at a desired temperature
Continued…………………………. 4) Microscope- Mono Ocular/binocular: Is an instrument used to see objects that are too small for the naked eye 5) Hot air oven: Are electrical devices used in sterilization 6) Autoclave: Is a device used to sterilize equipment and supplies by subjecting them to high pressure saturated steam at 121 °C for around 15–20 minutes depending on the size of the loads 7) Ph-meter: is an electronic instrument used for measuring the pH (acidity or alkalinity) of a liquid
Lab equipments • Incubator: Is a device used to grow and maintain of course microbiological cultures or cell cultures 9) Automated biochemistry analyzer: Is an instrument designed to measure different chemicals and other characteristics in a number of biological samples quickly, with minimal humanassistance 11) Enzyme-linked immunosorbent assay(ELISA) -Reader : Uses one sub-type of heterogeneous, solid-phase enzyme immunoassay (EIA) to detect the presence of a substance, usually an antigen, in a liquid sample or wet sample
Continued…….. 12) Microtome: Is a tool used to cut extremely thin slices of material, known as sections. Its used in microscopy, allowing for the preparation of samples for observation under transmitted light or electron radiation 14) Wax melting bath: Its a device used for electric melting of glues, vinyl compounds , waxes etc. with bottom valve discharge. Heaters are positioned such that melter may be used 1/3, 2/3 and full capacity without overheating contents 15) Hot plate: A hot plate is a portable self-contained tabletop small appliance that features one, two or more gas burners or electric heating elements
LIS • A lab information system ("LIS") is a class of software that receives, processes, and stores information generated by medical laboratory processes. These systems often must interface with instruments and other information systems such as hospital information systems (HIS) • A LIS is a highly configurable application which is customized to facilitate a wide variety of laboratory workflow models • It is a complete management system that handles all business functions from patient management, results generating, to physician decision making
Key Features • The lab machines including the auto analyzers are interfaced with the hospital information system and their complete operations are automated without human intervention • HL7 standards incorporates the ability to receive data from other lab machines • Sample management system creates barcodes and tracks the samples of blood, saliva, urine etc.
Continued………………………….. • Assures that the technicians complete all the pending tests • Generates automated results from various laboratory machines and updates patient records • Ability to handle large number of specimens without compromising on safety • Efficient tracking of specimens by usage of bar codes for the specimens
Benefits of Lab Information System Doctors • The lab results of critical patients would be notified instantaneously to the doctor • All the lab results would be submitted directly to the doctor Patients • No delay in the execution of doctors’ orders • No need to make repeat visits to collect the results • No mix-up of samples of different patients at the lab Lab Technician • Immediate receipt of the doctors’ orders to perform a lab test • Easier reporting of lab results of the patients
FUNCTIONS OF THECLINICAL LABORATORY • Identify the chemical composition of blood and urine samples • Identify and count the different types of cells found in blood and other body fluids • Blood typing and determination of transfusion compatibility between blood donors and recipients • The culturing and identification of bacteria and viruses from sites of infection in the body
The functional components of the clinical Laboratory • A hospital laboratory work generally falls under the following divisions: • Hematology • Serology • Clinical Chemistry/Biochemistry • Urinalysis • Microbiology • Blood Bank
Hematology • Hematology :-The study of blood. This section counts and qualifies the different types of blood cells and other components found in blood
Serology • Serology - The study of serum for its antibody content. Certain microorganisms (antigens) stimulate the body to produce antibodies during an infection. In the Serology lab, the antibodies react with antigens in specific ways that can be used to confirm the identity of the specific microorganism
Clinical Chemistry/Biochemistry • Chemistry - Performs most chemical analyses including glucose,sodium, potassium, and cholesterol.
Urinalysis • Urinalysis - The study of urine for the purpose of medical diagnosis. Urine is initially examined for such characteristics as color, odor, and specific gravity (density relative to water). It is routinely tested for its acidity level, as indicated by its pH reading, and screened for glucose (sugar)
Microbiology • Microbiology - The study of microorganisms, including viruses, that can only be seen with a microscope.
Blood Bank • Blood Bank - Collects, tests, types and stores blood donations used for blood transfusions
Functional planning An important decision in planning for a new laboratory is the physical location in relation to other departments • Functional planning covers the following activity: • Determining services to be provided for inpatients/outpatients, for other departments, smaller hospitals and private practitioners • Determining area and space requirement to accommodate equipment, furniture and personnel in technical, administrative and auxiliary functions • Dividing the area into functional units, hematology, biochemistry, microbiology, histopathology, urinalysis etc • Determining the major equipment and appliances in each unit
