Hyperthyroidism or Hypothyroidism ?

Your TSH is borderline elevated. (the 'third generation' bit is irrelevant). High TSH indicates an underactive thyroid (hypothyroid). TSH is the body's way of yelling at the thyroid to work harder. But since your level is only slightly increased, I'd be surprised if you got diagnosed as hypothyroid based on just that. More likely you'd be followed up with some more tests in a couple of months. There are other reasons why you can get a bordeline high result, such as some medications and other kinds of illness. There is a way that you can have elevated TSH and be hyperthyroid (a "TSHoma") but you'd be one in a million!
