Low FT4 and TSH?

[StinkyFinga]

I was just looking at some previous lab work and noticed that a my FT4 is at .7 (.6 - 1.6 range) and TSH is 1.8 (.34 - 5.00 range). Both on the lower end of the spectrum.

Do these numbers have any impact on testosterone levels ? As mentioned in my past post, my Test levels were 423.

your tsh is good, your ft4 is low though..im not sure what a good ft4 level is..mine came back at 1.22 and im not sure if that's good or bad..my tsh was 3.87 which is bad....but getting back to you, your tsh is good, ft4 is low which i think would lower your testosterone . 423 isnt THAT bad of a t level, yes it's low, and id like it higher with trt/thyroid medsr but it's not dramatically bad.
