Course description: The material presented in this course is intended to explain the role of the laboratory in diagnosing thyroid conditions/diseases and in determining the effectiveness of thyroid treatment. The basic biochemistry of the thyroid hormones and the feedback mechanism between the thyroid and pituitary will be discussed, as well as thyroid disorders and the assays used to assess thyroid function.
