Correct Answer is D
Explanation
A. “This test will inform your provider if you are anemic.” Hemoglobin and hematocrit levels are used to assess anemia, not creatinine.
B. “This test will inform your provider if you have a thyroid disorder.” TSH and T3/T4 levels assess thyroid function, not creatinine.
C. “This test will inform your provider if you have an infection.” Infection is usually assessed by WBC count, CRP, or cultures, not creatinine.
