Thyroid gland (Peripheral)

All relevant functional tests are explained with a detailed presentation of indications, contraindications, side effects, test preparation, framework conditions, specific instructions for the actual test execution, and the interpretation of test results. Specific normal ranges and cut-off values are always provided, even for special situations (gender, age, BMI, puberty phases, menstrual cycle phases, acute illnesses, medications, etc.). A special feature is the emphasis on test preparation, execution, and interpretation, as well as the interdisciplinary nature. In addition to thyroid hormones, thyroid autoantibodies, and the tumor markers hTg and calcitonin, the pentagastrin test, the calcium infusion test, and the rhTSH stimulation diagnostics are described in detail.
