Not likely: The lab parameters you describe are not consistent with graves disease. It would be prudent to discuss the matter with your doctor as all lab tests need to interpreted in the context of history, physical findings, imaging and other lab findings.

Probably not: People with graves disease typically have a low TSH along with high free T4 and/or high free t3 (liothyronine). Most people also have a high tsi titer, though not everyone does. If you have a low TSH and high free t4, you may have mild early hyperthyroidism, and it is possible that it is graves, so it is something to follow-up in the future. A more accurate antibody test than tsi is the TSH receptor antibody.
