Need more info: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your TSH is borderline high, T4 may be normal especially if you are taking birth control pills. It would be prudent to discuss this with your doctor at the next visit. http://www.nlm.nih.gov/medlineplus/ency/article/003517.htis
