Add a few business courses in the event you manage a laboratory or run your own practice. Supplement your academic studies by getting practical experience through internships. What if I like the work I could do in clinical chemistry but I don't necessarily want to go through all the schooling? Can I still work in this field?
You can still work in other capacities. How do I know this career will still be there for me when I graduate? Sick or healthy, people will always need medical information quickly, easily, cheaply. A new growth area, for example, is the use of "kits" in the home or at the hospital bedside, such as those for pregnancy detection or glucose diabetes monitoring. Clinical chemists may educate consumers or consult with physician offices on what the results mean and what the patient whether ill or healthy should do next.
Other growth areas will appear.
From Evidence to Best Practice in Laboratory Medicine
For example, the number of consumer groups who have special needs is increasing. These groups will continue to require new and different tests beyond what we provide today. New concerns such as environmental toxins and the spread of new diseases will heighten the demand for additional testing.
We will always need solutions; we will always need new methods for faster, more accurate, more precise, and more sensitive testing that is also less expensive. What about safety? This means that if you intend to begin a course on 16 September , we will not issue you with a CAS number before 16 June Your CAS number is only valid for one Tier 4 application. Deferrals Deferrals are considered on an individual basis.
Successful applicants may defer entry to the course for up to one year. Re-applications If you applied in the previous year and your application was not successful you may apply again. Your application will be considered against the standard course entry criteria for that year of entry. In your new application you should demonstrate how your application has improved. We may draw upon all information from your previous applications or any previous registrations at the University as a student when assessing your suitability for your chosen course.
Course details Course description Our MSc in Clinical Biochemistry will give you a thorough grounding in a discipline that deals with the clinical analysis of body fluids and other biological material to aid the diagnosis, therapy and monitoring of diseases. Clinical biochemists are typically clinical scientists who work in hospital laboratories providing advice and interpretation of analytical results to other healthcare professionals such as clinicians, general practitioners and nurses.
They are also involved in the development of new analytical methods and improvement of clinical services, including quality assurance and audit. Through this MSc, you will gain a core knowledge and understanding of the normal physiology and pathophysiology of the major organs and endocrine systems, as well as more specialist areas such as paediatric biochemistry and drug monitoring.
You will also develop a core knowledge and understanding of clinical disorders and how biochemical parameters and laboratory methods are used for the investigation, diagnosis and management of patients.
Aims We aim to give you: an advanced understanding and applied knowledge of the theory and practice of clinical biochemistry; a critical understanding of how biochemical investigations are employed to develop a clinical diagnosis; the necessary professional and research skills to promote lifelong learning and career development.
Special features Innovative teaching We utilise mobile technology in our teaching by providing you with an iPad for you to use throughout your studies.
Laboratory research experience You have the option to spend 10 weeks in the laboratory conducting research to present in your dissertation. Teaching and learning We use a range of teaching and learning methodologies throughout the course, including lectures, tutorials, workshops and interactive clinical case tutorials using mobile technology and iPads.
Some of these will be delivered online. Find out more by visiting the postgraduate teaching and learning page. A more precise quantitative estimate of the superiority of one test over another can be obtained by comparing the area-under-the-curve AUC for each test and applying statistics to determine the significance of the difference between AUC values.
The AUC range: However, other data using ROC curves to assess the ability of the tumor markers, prostatic acid phosphatase PAP and prostate specific antigen PSA , to differentiate prostate cancer from BPH and prostatitis at various cutoff values is illustrated in Figure 2. Once a clinical laboratory test with the appropriate diagnostic accuracy has been ordered, how are the results of the test interpreted?
Decision level refers to a particular cutoff value for an analyte or test that enables individuals with a disorder or disease to be distinguished from those without the disorder or disease. Moreover, if the diagnostic accuracy of the test and the prevalence of the disease in a reference population are known, then the predictive value of the decision level for the disorder or disease can be determined.
Reference interval relates to the values for an analyte eg, PSA, glucose, etc. All quantitative assays have a finite lower limit of detection LLD , distinct from 0, that more precisely constitutes the lower limit of the reference interval when this lower limit encompasses 0. Therefore, any PSA value less than 0. In addition, it is important to remember that reference intervals for an analyte are method dependent ie, the reference interval established using one method cannot automatically be substituted for that of a different assay that measures the same analyte.
Thus, reference intervals are intended to serve as a guideline for evaluating individual values and, for many analytes, information on the limits of an analyte for a population of individuals with the disease or diseases the test was designed to detect is even more informative. Also, it is important to recognize that values for some analytes in a population of healthy individuals may not be Gaussian distributed. Figure 2.
The reference interval for this data must be determined using a non-parametric statistical approach that does not make the assumption that the data is Gaussian distributed. Example of a distribution of laboratory test values for an analyte ie, the liver enzyme, gamma-glutamyl transferase [GGT] for which the data are not Gaussian distributed.
For example, alkaline phosphatase, an enzyme produced by osteoblasts bone-forming cells , would be expected to be higher in a healthy to year-old during puberty and the growth spurt ie, increased bone formation during lengthening of the long bones that normally accompanies puberty in adolescent males and females than those observed in a prepubertal or elderly individual. Ideally, the best reference interval for an analyte would be individual-specific such that the value for the analyte, determined when the individual is ill, could be compared with the limits for this analyte, established on this same individual, when he or she was healthy or without the illness.
For obvious reasons, it is difficult, if not impossible, to obtain such reference intervals. Thus, population-based reference intervals offer the most cost-effective and rational alternative.
When using population-based reference intervals, however, it is critical that members of the reference population be free of any obvious or overt disease, especially diseases likely to affect the analyte for which the reference interval is being determined. For example, when determining a reference interval for TSH also known as thyrotropin , it is critically important that the population of individuals tested be free of any pituitary or thyroid disease likely to affect the pituitary-hypothalamic-thyroid axis, which, under the action of the thyroid hormones tri- T3 and tetraiodothyronine T4 , exert regulatory control over circulating levels of TSH.
Quantitative values for all analytes are affected by both imprecision ie, lack of reproducibility in the measurement of the analyte and intra-individual variation over time in the concentration of the analyte due to normal physiologic mechanisms ie, biological variation that are independent of any disease process. For example, the analyte cortisol, a glucocorticoid produced by the adrenal cortex that is important in glucose homeostasis, normally displays diurnal variation.
Blood cortisol levels begin to rise during the early morning hours, peak at mid-morning, and then decline throughout the day to their lowest level between 8 pm and midnight.
Clinical Chemistry as a Career
The degree of imprecision ie, lack of reproducibility in the quantitative measurement of any analyte is given by the magnitude of the coefficient of variation CV , expressed usually as a percent, obtained from multiple measurements of the analyte using the formula: There is a direct relationship between the magnitude of the CV and the degree of imprecision ie, the lower the CV, the lower the imprecision [or the higher the degree of precision]. The magnitude of analytical variation is given by CV a , while biological variability is defined by CV b.
In addition, a change in values for an analyte that exceeds the change ie, reference change value [RCV] expected due to the combined effects of analytical and biological variation alone is due most likely to a disease process or to the affect of any therapy on the disease.
More recently, neural networks, a branch of artificial intelligence, have been used to evaluate and interpret laboratory data. Neural networks have been applied to such diverse areas as screening cervical smears Pap smears for the presence of abnormal cells and the identification of men at increased risk of prostate cancer by combining values for PSA, prostatic acid phosphatase PAP , and total creatine kinase CK.
The use of neural networks in clinical and anatomic pathology is likely to expand because of their ability to achieve a higher level of accuracy than that attained by manual processes.

Laboratory test results may influence up to 70 percent of medical decision making. Lopasata, to the sparse training in laboratory medicine provided in most United States medical schools.
In the final analysis, it is important for clinicians and lab-oratorians to recognize that laboratory data, although potentially extremely useful in diagnostic decision making, should be used as an aid and adjunct to the constellation of findings eg, history, physical exam, etc. Laboratory data is never a substitute for a good physical exam and patient history clinicians should treat the patient, not the laboratory results.
