What is this course about? 1.1 Course description Medical biochemistry is the area of general pathology that performs analyses on human specimens such as blood plasma and serum, urine, cerebrospinal fluid, serous fluids and tissue biopsies. The course describes common tests used to assist with the diagnosis and treatment of human diseases. On completion of this course, you will be able to demonstrate and evaluate current knowledge in the basic principles and practices of the medical biochemistry laboratory, including disorders of amino acid and carbohydrate metabolism, dyslipidaemias, and routine chemistries for major organ system functions. 1.2 Course content Basic principles and practices in the medical biochemistry laboratory Human specimen collection for diagnostic testing in clinical chemistry Critical correlations and analytical procedures in medical biochemistry Biochemistry of disorders of carbohydrate, lipid, amino acid and protein metabolism Common analytes used to assess human organ system functions, including diagnosis of renal, cardiac and liver function Analytical techniques in medical biochemistry, including spectrophotometry, electrophoresis, blood ph and gas analysis, and immunoassay Evaluation of analytical data and scientific report writing skills Critical review of scientific literature 2.
