Endocrine tests can be performed through imaging, urine, functional tests, cytology or biopsy, and genetic material tests in addition to blood draws. 1. Blood test, blood test is one of the commonly used test methods, mainly through the measurement of changes in the concentration of various endocrine-related substances in the blood for the detection of functions and the determination of diseases. For example, blood glucose is measured to diagnose diabetes, and blood T3 and T4 are measured to diagnose thyroid diseases. 2. Imaging examination, including X-ray, ultrasound, CT, MRI, radionuclide examination, etc., for endocrine organs such as pituitary gland, thyroid gland, parathyroid gland, gonads and adrenal glands. 3. Urinalysis, which measures the level of hormone metabolites in the urine in response to hormone levels. 4. Functional tests, which mainly check the function of the corresponding endocrine gland of the patient through diagnostic medication. 5. Cytology or biopsy, by obtaining a tissue specimen to clarify the benign or malignant nature of the lesion. 6. Genetic material examination, including chromosome and gene examination, mainly to clarify whether the cause of the patient’s disease is hereditary. Patients with endocrine diseases should choose the appropriate test under the guidance of their doctors.
