The analysis of body fluids, both blood and urine, can present a powerful diagnostic tool for the assessment of human health and disease. In this practical session the students will utilize multi-function dipsticks (Multistix®) to analyse urine samples (artificial) from a number of patients and use their results to make a clinical diagnosis as to the patient’s medical condition. In the second part of the laboratory session the students will use a simple two-step biochemical reaction that produces a colour change to make their own biosensor to detect the presence of glucose in urine samples.
