Which of the following components is not required in the urinalysis for a DOT medical exam?

Specific Gravity.
Blood.
Ketones.
Protein.

The correct answer is: Ketones.

In a DOT medical exam, certain components of a urinalysis are specifically required to assess the candidate's overall health and fitness for driving. Among those components, specific gravity, blood, and protein are included because they provide vital information about kidney function and hydration status, as well as potential underlying medical conditions. Specific gravity evaluates urine concentration, indicating hydration levels. The presence of blood in the urine might suggest urinary tract issues or other medical concerns, while protein in the urine can point to kidney damage or disease. Ketones are not routinely required in the urinalysis for a DOT medical exam. While the presence of ketones can be important in certain medical contexts, particularly for individuals with diabetes, they are not a standard test component for assessing fitness for duty in commercial driving under DOT regulations. Therefore, the option mentioning ketones is accurate as it does not belong to the mandatory components of a DOT medical examination urinalysis.
