what is the relation between low TSH and high PTH?
In my annual exam report, I had low TSH (0.04), mild high T4 (4.7). My doctor tested me for TSI to see if I have Grave's disease. My TSI is normal. but my PTH and ionized calcium are mildly elevated. And, now I am really confused. If I have hyperparathyroid, what does it have to do with TSH and T4?
