Answer
The abnormal finding in a fasting urine sample is protein (proteinuria).
Solution
1. In a healthy individual during a fasting state, the urine should have minimal or no protein.
2. The normal kidney is efficient at filtering plasma, reabsorbing useful substances, and preventing significant leakage of proteins into the urine.
3. Therefore, when a fasting urine sample shows protein (i.e., proteinuria), it indicates an abnormality in the filtration barrier of the kidney or a renal pathology.
Thus, the abnormal finding in a fasting urine sample is the presence of protein, i.e., proteinuria.

An abnormal finding in a fasting urine sample often includes the presence of glucose, which may indicate conditions like diabetes mellitus or renal glycosuria. Under normal circumstances, our kidneys should reabsorb glucose, so it’s a red flag if glucose molecules are sneaking their way into your pee! Another unusual culprit to look out for is protein. A little protein in urine might happen after a workout, but significant amounts can suggest kidney issues or other medical conditions. It's a good reason to schedule a check-up with your healthcare provider!
