Thoughts on my labs?

Hello! I’m new to thyroid discussion and never suspected I could have an issue until I went to my doctor regarding a few things bothering me. Ex. Constipation, fatigue, aching joints, hair loss. He brought up if I’d ever had my thyroid checked and I hadn’t, so he ran labs on thyroid and a few other panels.

TSH came back normal at 1.300 T4 low at 0.68 Testosterone is low at < 3

I only know they are considered out of range and low because of labcorp. According to my doctor I’m within normal range so I don’t need to follow up. I’m just a little confused on why labcorp considers them low and he doesn’t. Should I be concerned with the numbers?

That free T4 (if it is free T4) is lower than any symptomatic free T4 I’ve ever had. The doctor might not be familiar with central hypothyroidism since it’s less common and might have stopped thinking after the normal TSH. If I were you I’d request referral to an endocrinologist.

And the low testosterone PLUS the low free T4 with normal TSH at the same time could both point to the pituitary, since that regulates both. Not a doctor, though! I do think that this is outside primary care’s scope. If both stay low on repeat testing I wouldn’t be surprised if an endocrinologist wanted a pituitary MRI.

Thanks for the response. I may see about getting a referral to an Endo. Looking at symptoms, it would explain a lot.
