Question

Quizplus · Accepted Answer

Radioimmunoassay is a specific test used to measure thyroid hormone levels in the blood, allowing for the evaluation of thyroid function. MRI and CT scans are imaging tests that are not specific for evaluating thyroid hormones. Cortisol level determination is a test used to evaluate adrenal function, not thyroid function.
