Consequently, organizations are constantly resorting to technological solutions to meet up with the ever increasing demand for quality and speedy service de colouredy and with virtually everything in our day to day lives being technologically impelled, should there not be a scenario where paper documentation is completely annihiformer(a)d from medical exam laboratories?, where a system is adopted in which patient account take fors and data are correctly stored such a s to enable features such as patient/ visitor history tracker, where a returning patients history can aid the laboratory in deducing what type of test a visitor would request for, statistical reports generation where useful statistical information is inferred ground on test results e.g whether or not there is an increase or decrease of spic-and-span HIV infections, should there not be a software/application where other stakeholders in the health-care delivery processes such as doctors and pharmacists beget rag to laboratory generated information to aid in their health-care administration?, should the retrieval of patient test records be slow and cumbersome?, why must results be entered directly on the result document, and then a embossment reduplicate is unavailable. Questions such as these will serve as a take up to the development of a robust system than manages various tasks in the medical laboratory.1.3 RESEARCH QUESTIONSBased on the statement of the problems above the r esearch head teacher for this study areHow will the development of a laboratory information management System greatly increase the laboratorys efficiency?OBJECTIVE OF STUDYTo design a robust Laboratory information System that will efficiently aid in the running of the laboratory facilityTo hold and provide timely information about each visitor to the laboratoryTo reduce the need to hire staff through the proper application of technological solutions therefore cutting cost.With a proper functioning and comprehensively designed application, Laboratory tasks such the following can be achievedSAMPLES worryA LIMS can automate the management of samples. An organization can configure its analytical parameters and calculations into the LIMS before implementing the software in the laboratory. After sample registration, the system can print barcodes which it can scan at the end of the analytic thinking when loading results into the LIMS. The system can check the completed results, automati cally authorize those which comply with specifications and reporting (but not validating) out-of-specification results. A LIMS may release or retain lots and batches, according to a laboratorys specifications and calculations.Once results come available for the labs clients or owners, they can extract them inPDF, XMLor spreadsheet files from the LIMS interface. (Note that moving inferior data to a spreadsheet may lose the traceability of changes).LABORATORY USERSOne may configure a LIMS for use by an unlimitednumber of users. individually user owns an interface, protected by security mechanisms such as a login and a password. Users may have customized interfaces. A laboratory manager dexterity have full access to all of a LIMS functions, whereas technicians might have access only to functionality needed for their individual work-tasks.ADMINISTRATIVE TASKS AUTOMATIONAs of 2009LIMS implementations can manage laboratory sampling, consumables sampling schedule and financial (invoic es). background OF STUDYBakor checkup centre has various departments and sections ground on the issue at hand to be dealt with however this study focuses mainly on the lab processes, including data collection and management.This study takes the patient from the moment of entry into the medical centre, filling forms, up till the moment the test is taken, from that tailor onwards the study will focus on the methods used by the laboratory attendant to collect and store data, through recording of findings and obligingness of resultsThis study will also concentrate on data backup and retrieval methods and will highlight potential errors and problems that could be encountered if the entire process was carried out manually instead of using a well tack together computer application.SIGNIFICANCE OF STUDYThe Computer establish Laboratory information management System is quite desirable as it will proceeds the laboratory in the area of repetitive task automation. It will serve as an assi stant to the medical laboratory scientist. It will also gain ground patients as they will be able to retrieve record from introductory visits to the laboratory.LIMITATIONS OF STUDYThe limitations of this study includeInability to obtain actual test result document, as this goes against medical ethics for a third ships company to view Laboratory specimen or test results.Unavailability of capable laboratory scientist at the study locations to properly explain terms and laboratory procedures.LITERATURE REVIEWFrom tasting piss to microscopy to molecular testing, the sophistication of symptomatic techniques has come a long way and continues to develop at dangerous speed. The history of the laboratory is the story of care fors evolution from empirical to experimental techniques and proves that the clinical lab is the true source of medical authority.Three distinct periods in the history of medicine are associated with three dissimilar places and therefore different methods of dete rmining diagnosis From the snapper ages to the 18th century, bedside medicine was prevalent then between 1794 and 1848 came hospital medicine and from that time forward, laboratory medicine has served as medicines lodestar. The laboratorys contribution to modern medicine has only recently been recognized by historians as something more than the addition of another resource to medical erudition and is now being appreciated as the seat of medicine, where clinicians account for what they prise in their patients.The first medical diagnoses make by humans were based on what ancient medicos could observe with their eyes and ears, which sometimes also include the examination of human specimens. The ancient Greeks attributed all disease to disorders of bodily fluids called humors, and during the late medieval period, doctors routinely performed uroscopy. subsequent, the microscope revealed not only the cellular structure of human tissue, but also the organisms that cause disease. More sophisticated diagnostic tools and techniques such as the thermometer for measuring temperature and the stethoscope for measuring heart rate were not in widespread use until the end of the 19th century. The clinical laboratory would not become a standard fixture of medicine until the beginning of the twentieth century.Ancient diagnostic methodsIn ancient Egypt and Mesopotamia, the earliest physicians made diagnoses and recommended treatments based primarily on observation of clinical symptoms. Palpation and auscultation were also used. Physicians were able to describe dysfunctions of the digestive tract, heart and circulation, the liver and spleen, and menstrual disturbances unfortunately, this empiric medicine was reserved for royalty and the wealthy.Other less-than-scientific methods of diagnosis used in treating the middle and lower classes included divination through ritual sacrifice to counter the outcome of illness. Usually a sheep would be killed before the statue of a god . Its liver was examined for malformations or peculiarities the shape of the lobes and the orientation of the common duct were then used to predict the fate of the patient.Ancient physicians also began the practice of examining patient specimens. The oldest known test on soundbox fluids was done on water in ancient times (before 400 BC). Urine was poured on the ground and find to see whether it attracted insects. If it did, patients were diagnosed with boils.The ancient Greeks also saw the value in examining body fluids to predict disease. At close to 300 BC, Hippocrates promoted the use of the mind and senses as diagnostic tools, a principle that played a large part in his reputation as the Father of Medicine. The central Hippocratic principle of humoral pathology attributed all disease to disorders of fluids of the body. To obtain a clear house painting of disease, Hippocrates advocated a diagnostic protocol that included tasting the patients water supply, listening to the lungs, and law-abiding skin color and other outward appearances. Beyond that, the physician was to catch the patient as an individual. Hippocrates related the appearance of bubbles on the surface of pissing specimens to kidney disease and chronic illness. He also related certain water system sediments and root and pus in piddle to disease. The first description of haematuria or the presence of blood in urine, by Rufus of Ephesus surfaced at well-nigh AD 50 and was attributed to the failure of kidneys to function properly in filtering the blood.Later (c. AD 180), Galen (AD 131-201), who is recognized as the founder of experimental physiology, created a system of pathology that combined Hippocrates humoral theories with the Pythagorean conjecture, which held that the four elements (earth, air, fire, and water), corresponded to various combinations of the physical qualifies of dry, cold, hot, and moist. These combinations of physiologic characteristics corresponded roughly to t he four humors of the human body hot moist = blood hot dry = yellow bile cold moist = unconcern and cold dry = black bile. Galen was known for explaining everything in light of his theory and for having an explanation for everything. He also described diabetes as diarrhea of urine and noted the normal relationship between fluid intake and urine volume. His unwavering belief in his own infallibility appealed to complacency and reverence for authority. That bigotry essentially brought innovation and discovery in European medicine to a standstill for nearly 14 centuries. Anything relating to anatomy, physiology, and disease was simply referred back to Galen as the final authority from whom there could be no appeal.Middle AgesIn medieval Europe, early Christians believed that disease was either punishment for sin or the result of witchcraft or possession. Diagnosis was superfluous. The basic therapy was prayer, penitence, and invocation of saints. sic medicine based diagnosis on symp toms, examination, pulse, palpitation, percussion, and inspection of excreta and sometimes semen. Diagnosis by water casting (uroscopy) was practiced, and the urine flask became the token of medieval medicine. By AD 900, Isaac Judaeus, a Jewish physician and philosopher, had devised guidelines for the use of urine as a diagnostic aid and under the capital of Israel Code of 1090, failure to examine the urine exposed a physician to public beatings. Patients carried their urine to physicians in decorative flasks cradled in wicker baskets, and because urine could be shipped, diagnosis at long distance was common. The first book detailing the color, density, quality, and sediment found in urine was written around this time, as well. By around AD 1300, uroscopy became so widespread that it was at the point of near universality in European medicine.Consequently, the clinical laboratory became a standard fixture of medicine at the beginning of the twentieth century it is now an integral pa rt of the health-care delivery process and is seen as the basis for medical diagnosis.In recent times a medical laboratory scientist (MLS), formerly known as a medical engine driver (MT) or clinical laboratory scientist (CLS), functions as a medical detective, performing laboratory tests that provide physicians with information that assists them in preventing, diagnosing and treating diseases and maintaining patient wellness.The medical laboratory scientist performs a wide variety of laboratory tests, ranging from simple dipstick urine tests to complex DNA tests that help physicians assess risk of diseases. Using test results, physicians can uncover diabetes, cancer, heart attacks, infections and many other diseases.Medical laboratory scientists interact with physicians, nurses, pharmacists, and other members of the healthcare team to provide timely, accurate information so the patient can receive the correct medical treatment.Medical laboratory scientists use sophisticated biomedi cal instruments and technology, microscopes, complex electronic equipment, computers, and methods requiring manual dexterity to perform tests on blood, body fluids, and tissue specimens. Clinical laboratory testing sections include clinical chemistry, hematology, Immunohematology (Blood Bank), immunology, microbiology and molecular diagnostics.EFFECTS OF MEDICAL LABORATORIESMedical Laboratories have played a pivotal role over the years. As stated above, in ancient times, physicians relied on various inaccurate actor of disease diagnosis such as urine tasting, listening to the lungs etc. However with the advent and subsequent evolution of modern medical laboratory facilities, plus the discovery of the cellular nature of human tissue and the intent of the microscope, medical diagnosis made a tremendous leap from a 50-50 truth ratio to an 80% accuracy rating for laboratory based medical diagnosis. Therefore the use of medical laboratories has greatly increased the accuracy of diagno sis thusly the physician can administer the proper lovely of treatment.The use of laboratories has also led to various discoveries, such as natural strands of Viruses, bacteria, parasites and fungi. It also acts as a monitor for new strands of drug repellent bacteria.CHALLENGES FACED BY MEDICAL LABORATORIESThe main challenges and bottle-necks encountered by medical laboratories over the years include.Inability to preserve patient samples or specimens such as blood, sputum, stool, over a long period of time for reference purposes hence making patient to specimen matching and tracking,Efficient information sacramental manduction and retrieval between the laboratory scientist and those administering treatment has been a problem.MEDICAL LABORATORIES IMPROVEMENTS AND THE future(a)For the efficient functioning of the diagnosis system, health-care delivery, scientific research into bacteriology and disease cause organisms, technology should be applied to automate administrative tasks , such as the visitor registration and result documentation. By making judicious use of computer software to automate and manage tasks in the laboratory there will be a dramatic increase in its efficiency.Consequently this will greatly reduce the need to recruit and pay personnel department to defend out administrative duties therefore such resources can be channeled towards more important needs of the laboratory.TECHNOLOGY PLATFORM/PROGRAMMING vocabulary TO BE USED IN STUDYThe technologies to be used in the development of this Laboratory Information Management system is an open source computer programming language known as PHP, together with a MYSQL driven database, a solid browser based application will be developed.PHP PHP also known as Hypertext Pre-processor, it belongs to a class of languages known as middleware (Needham, 2006). These languages work closely with the web server to interpret the request made from the web, processes these request, interact with other programs on the server to fulfill the request and then indicates to the web server exactly what to serve to the clients browser.It is the leading web programming language for design of web applications. It possesses a language similar to C, coffee or Pearl. Its uses include retrieving user input and saving it in a database, retrieving information from a database and general data manipulation processes.THE CLIENT obviously refers to end users of an application that connect to a remote server to carry out computational processesTHE host An application known as a web server listens for requests a client makes, responds to those requests and serves out the appropriate solution (Greenspan, 2002)MYSQL Refers to an open source relational database management system with a plume of programs that access and manipulate these records. (Descartes, 2003).It is arelational database management system (RDBMS)that runs as a server providing multi-user access to a number of databases.APACHE WEB SERVERApac he is a web server notable for playing an important role in the initial growth of the world-wide web.It is responsible for accepting Hypertext Transfer communications protocol (HTTP) request from web client (web browsers) and serving the HTTP responses along with optional data content which usually are HTML pages.These political platforms are used in this research work becauseThere are open source import there are free to use and develop with without having to purchase licenses or fulfill any legal obligation to the owners of the technology.It is easy to deploy on a local machineIts hardware requirements are minimal therefore making its installation and usage less cumbersome.Developer tools and support services for the platform/technology are readily available at absolutely no cost.DATA COLLECTED FOR LABORATORY TESTLab Investigation trope This form is used for general patient registration and data collection. information collected on this form includePatient NamePatient ageHospi tal NumberSpecimenBlood Specimen indifferenceStoolUreaVarious SwapInvestigation RecordClinic enlargeName of DoctorLab Request Book Used to record Patients data for that day.NameLab Investigation DoneAmount sequence inData Collected for lab testsLab result book (Used for recording patients results)Patients Name fancy of birthGenderTest ResultsDateHospital registration NumberExtra CommentsSUMMARYThe use of technological solutions greatly reduces costs, increase profits, save human effort and provide burst services to customers/clientsThe use of an LIS (Laboratory information System) in the running of a medical laboratory facility greatly improves the documentation process makes patients records retrieval a lot easier and faster, records are not lost and are kept safe(p) via regular backup of the available data.With the use of a Laboratory information system, various kinds of data deductions, surveys and reports can be easily generated for statistical purposes such as the average pe rcentage of persons with a certain kind of disease, genetic constitution or blood type etc.CONCLUSIONA properly developed Medical Laboratory information system will greatly increase productivity, increase the quality of services delivered by the facility and greatly reduce the amount of man hours put into the delivering the laboratory services
