Did the doctor prescribe any medicine? Two weeks and a blood test sound a lot like a follow-up for thyroid function after initiating thyroid medication. It is not unheard of for a doctor to find an abnormal lab test, explain everything to the patient, and the patient doesn’t remember much, assuming it’s normal. If you choose to go to another hospital, it would be best to ask for the laboratory results and bring all the medication, if any, with you.
