FREE T3

[Aidan_]

I just sent for my full thyroid from medichecks. I went over an old test back in 2015 a FREE T3 only done privately.

Never diagnosed with thyroid issues NHS keep saying all is normal. What can FREE T3 be with?

Is this auto immune or just T3 hormone issues?

My result back then said my result was 'insufficient' on FREE T3 the Normal Range was 3.1 to 6.8 County Pathology Ltd. I have no clue how I ever missed this test
