Using the results from each urine sample, along with Table 3, diagnose the condition(s), if any, that each sample patient is experiencing.. 2. If you were a doctor and a patient’s urinalysis came back with a high level of glucose, ketones, and an acidic pH, what diagnosis would you immediately consider? 3. If you were a doctor and a patient’s urinalysis came back with an alkaline pH and high levels of protein, what diagnosis would you immediately consider? 4.
