I recently had a TSH reflex and FT4 test to check my thyroid. My TSH reflex was 4.23 H (normal range is .27 - 4.20, so it's .03 over the limit) and my FT4 was 0.81 L (normal range is .93 - 1.70, so it is .12 lower than normal). Do I need to be concerned? Do I need a supplement with just a few points difference? I am 66 years old and in pretty good health, but had a mastectomy in 2003 and was on Arimidex but off it now.
