Post-Lab Questions
”1. Fill in Tables 9 through 12. Refer to Table 3 to determine if each result was normal or
abnormal. If abnormal, include the data which indicates this (e.g., a pH of 3.2 means that
glucose is present). Using the test results from each of the urine samples, diagnose the
condition(s), if any, that each of the sample patients is experiencing. ”

”2. If you were a doctor and a patient’s urinalysis came back with high level of glucose, ketones
and an acidic pH, what diagnosis would you immediately look into? ”
”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 look into? ”
