So, you've usually got T3 and T4 on one side of the lab report and then TSH on the other. Basically, those first two are your thyroid hormones, while TSH actually comes from your pituitary gland. Most of the time, theyβre just dancing together in this negative feedback loopβkind of like how a thermostat works in my house; if your T3 and T4 levels get too high, your body dials back the TSH, and if those levels drop, your TSH spikes to try and compensate. But honestly, looking at these numbers is way out of my league, and even a regular GP shouldn't be playing guessing games with them; you really need to leave this stuff to an endocrinology specialist to get a real answer.
