Yes, it is possible to have a high TSH result while simultaneously having hypERthyroidism. The tests for hyperthyroidism must be used together to give an appropriate impression of thyroid function and diagnosis of dysfunction. The TSH test only tests the hormone called Thyroid Stimulating Hormone, which is produced in the brain and turns the thyroid on. To test for hyperthyroidism, your doctor will need to test Free T3 and Free T4. These are the hormones produced by the thyroid. If the pituitary gland in the brain is overproducing TSH (often due to a tumor) while the patient has concurrent thyroid disease such as Graves' Disease; overconsumption of iodine; thyroid tumor or other cause of hyperthyroidism; the patient will have an elevated TSH along with elevated Free T3, and Free T4 levels.
