An osmometer was used to test the samples. Dependent Variable urine and plasma values Independent Variable fluid intake Controlled Variables room temperature, age, gender, and weight 4. Subjects were asked to refrain from alcohol and caffeine for a day before the start of the experiment. Explain why this is important. Both have a diuretic effect increasing water loss. 5. What technique was used to measure urine and plasma osmolarity? An osmometer was used to test the samples. Results Table 3.
