A patient reports symptoms of fatigue, weight gain, and thinning hair. Which of the following blood tests should the medical assistant anticipate the provider to order?

An electrolyte panel measures the levels of various electrolytes in the blood, such as sodium, potassium, and calcium. While abnormalities in electrolyte levels can indicate certain health issues, they do not specifically assess thyroid function or relate directly to the symptoms of fatigue, weight gain, and thinning hair.

A urinalysis tests for various substances in the urine and can help diagnose conditions related to the kidneys or urinary tract. However, it does not provide information about thyroid function and is not relevant to the symptoms described, which are more indicative of potential thyroid issues.

Blood cultures are performed to detect the presence of bacteria or fungi in the bloodstream, which is important for diagnosing infections. These tests are not appropriate for evaluating symptoms associated with thyroid dysfunction, such as fatigue, weight gain, and thinning hair.
