INTRODUCTION
The world that we live in is growing fast. There is a marked increase in the population nationwide along with increasing number of individuals being ill.
Point of care testing is an outcome of the problems that the world is facing due to overcrowding, very high patient-physician ration and lack in proper laboratory services.
Although point of care testing is being widely used but when compared with the laboratory testing there are lots of questions that arise with regards to the performance of both the methods.
In further discussion we shall compare the two and cover every aspect of each of the method and shall decide as to which is the method that should be put to use.
DISCUSSION
During my literature review I found interesting facts that I

These are: o Pre-measurement Uncertainty: this is the change in sample that occurs during transport, storage and sample preparation. For example blood glucose metabolism, increased serum potassium concentration etc.
These changes may alter the result.
Clinical laboratories face these much more as the sample takes time to reach the lab from the patient.
Where as in POCT there are less chances of this uncertainty, as the sample is taken right at the time of test but at times factors like blood clotting may affect the result too. o Measurement uncertainty: this type of uncertainty is caused during the coarse of the process starting from placing the sample in the analyzer till it produces results. These changes include calibration of machine volume of sample and reagents etc.
In laboratories regular maintenance of the analyzers, proper measurement of samples and accuracy in method may avoid these.
POCT is a method used by trained as well as untrained people therefore the best way to avoid these errors is to read the guide of the device properly
are more uncertain than the others? How could uncertainty be worked into the analysis? Is
To identify systematic error the experiment must be repeated. When repeating the experiment new apparatus or materials must be used, such as new stock solutions of hydrogen peroxide. If the new data differs consistently from the original data this indicates systematic error is present.
Consults with physicians, hospital personnel and independent and hospital laboratory personnel regarding common laboratory problems.
The instruments used in this experiment is an analytical balance to ensure precision. In order to
of being able to analyze multiple samples in a short amount of time. The most efficient way of determining concentration is to prepare a set of standard solutions of known
Clinical laboratories are reaching the 6 Sigma performance methodology in the analytical stage of a particular test. However, regardless of the commercialization, physicians are still ordering the incorrect tests during the pre-analytical stage of laboratory testing. In turn, a major portion of physicians are then misinterpreting the incorrect tests ordered in the post-analytical stage of testing (Wolf, n.d.). Another point, studies performed
The cost of diagnostics is also one of the important factors for developing rapid kits. To decrease the cost, several parameters should be considered: (1) minimal use of expensive reagents, (2) inexpensive manufacturing for mass-production, (3) quality control, and (4) miniaturization. In addition, for clinical use of medical diagnostic devices in resource-limited settings, environmental
However, to satisfy the demand, outside laboratories and physician office laboratories have since been created. Usage of these laboratories has shifted from tests used to corroborate a diagnosis to actually a diagnostic tool itself in addition to continuance research. The clinical laboratory has since evolved beyond its reliance on physicians, particularly pathologists, to include phlebotomists, medical laboratory assistants, and medical technologists, all with varying levels of education and training in the processing of specimens. To further improve the efficiency of the clinical laboratory, divisions have been established for specific types of testing including: chemistry, hematology, coagulation studies, microbiology, serology, blood bank, and urinalysis. While the laboratory has come to include tests on additional body fluids such as sputum, stool, spinal fluid, and more, the original fluids urine and blood are still the quintessential fluids for
The sample is taken with a fine needle. The cell/tissue sample is examined under a microscope for cell count, health, disability, etc.
Point-of-care Testing (POCT) is defined as a quality medical technology that provide many more opportunities in diagnostic assays to be performed at the site of patient care provision (Collinson et al., 2015 & Wu, 2014). For these reasons, assays are performed in sites such as the emergency department (ED), community health centres, chest pain evaluation centre, and intensive care unit rather than in the laboratory remote to patient care. POCT allows more rapid clinical decision making by reducing the turnaround time spent in test ordering, collection of specimen, transport and data reporting essential in most clinical laboratories (Straface et al., 2008). A familiar POCT assay to both providers and patients, is the

As a result of this finding, the Head of Quality Assurance has requested full validation to be performed on the method to assure the quality of the assay results generated
Genitourinary problem in female have a number of symptoms and these symptoms requires clinical skills to focus on problem history and examination. The context of assessing genitourinary problem is based on a number issues such as gynaecological background, family history, obstetric history and sexual history. Having lower pain being experienced in upper urinary track and iliac fossa pain experienced in ectopic pregnancies are some of the symptoms produced by genitourinary pathology(Detollenaere, et al., 2015). According to description of 51 years old female, having lower abdominal pain and 100 degrees temperature and the problem persisting for a while should undertake genitourinary examination as well as laboratory tests.Therefore, the study reveals genitourinary problem from examination, findings and treatment framework.
A number of random and systematic errors have affected the experiment. According to the relationship of,
Moreover, all plant instruments and measurement devices need to be listed, then classified into ‘critical’ and ‘non-critical’ devices. Once this has been agreed, the calibration range and required tolerances need to be identified. Decisions then need to be made regarding the calibration interval for each instrument. In addition, the company must identify current calibration status for every instrument across the plant.
