abnormal thyroid readings on blood test

i had a quick question. i went to the doctor last week to have some blood work done. well when the results from them tests came back it should i had some abnormal readings on the thyroid.it showed my t4 was at 2.03 with the normal being 0.93 to 1.70 then my t3 was 4.34 with the normal being 2.57 to 4.43 then he said the stimulating hormone which comes from the pituitary gland was 0.66 normal is 0.27 to 4.20 he said these tests may indicate hyperthyroidism but they are not clear cut. so that brings me to my first question. what do these tests say that isnt very clear cut? from what i have seen online as long as either your t3 or your t4 is elevated then you have hyperthyroidism. i did set up a appointment to see a endocrinologist but that isnt until september 12th. so if i do have hyperthyroidism isnt that a long time to be waiting to treat this problem?

Would repeat the TSH along with Free T4 & T3 in 3-4 weeks as the T4 elevation may indicated early HYPER and the TSH has not had time to significantly decrease yet.  The higher T4 than T3 would indicate either thyroid hormone ingestion (not apparently the case) or perhaps thyroiditis (usually transient) -- in any case the key will be lab monitoring to establish a pattern.
