Can't decide if I have a thyroid issue or not.

My hair has been thinning for about 5-6 years, I had increasingly worse fatigue and I've been gaining 10-15 pounds a year. Thankfully I was recently discovered to have low Vitamin D (24) do since going on daily OTC pills, the fatigue has gotten better thank God. But I still wonder about the hair. One PCP recommended I take OTC Biotin and another that I use Rogaine but I always wonder if I have an undisclosed thyroid issue. In October my free t4 was 1.28, total t3 1.8 with a TSH at 4.34. In February my free t4 was 1.11, free t3 2.33 with a TSH at 2.084. Since I think those numbers are pretty stable, are there other tests I should consider? Should I see a more specialized doc? I

Healthy people do not have a TSH of 4.34 mU/L. Test thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb).

In trying to assess a person's thyroid status,  most important is an evaluation for symptoms that occur more frequently with hypothyroidism.    Fatigue, weight gain and hair loss may be associated with hypothyroidism and other causes.    Do you have any other symptoms?  Next is confirmation with biochemical tests.   Red_Star was correct that the high TSH means you should test for those to see if Hashimoto's Thyroiditis is involved.  Before further discussion, in order to evaluate your other test results we need for you to please post the reference ranges shown on the lab report for the FT4 and FT3 tests.
