Nuclear medicine is a department specializing in the treatment of thyroid diseases, also known as isotope department (old name), featuring radioactive iodine treatment of hyperthyroidism, nail cancer and other thyroid diseases, and most tertiary hospitals nationwide have set up nuclear medicine departments. It is most convenient to use the medical card for registration. It can be associated with the medical insurance card, and there is no queue for registration and payment, which can be done in the lobby on the first floor of the outpatient clinic. If you want to have a blood test, you should go to the clinic as early as possible in the morning. Fasting is not required for thyroid function and blood tests, but fasting is required for liver and kidney function, lipids, blood glucose and blood sedimentation. You need to make an appointment in advance for thyroid ultrasound. If you have had an ultrasound or a thyroid ultrasound with a physical examination report at an outside hospital, it is best to bring it with you, and if you can, you do not need to repeat it. The results of thyroid antibody tests and other tests cannot come out on the same day, it takes about 2-3 days; the results of thyroid function tests, blood routine, liver and kidney function, blood lipids, blood glucose, blood rheology, etc. can all be obtained on the same day. That’s all I can think of for now, if you want to ask some other questions, feel free to consult online and wish you good luck with your medical treatment.
