Dr wants to run some more tests after Thyroid Panel

[MooseBeTimeForSnow]

I had bloodwork on Friday - my Dr requested a Thyroid panel. The office rang this morning to say one of the results was low and the Dr wants further tests for CRP, TRO and Ferritin.

Any ideas on what the train of thought is? I’m in Canada, so the ranges might be different:

T3 Free 5.1 (range 3-6.5)
T4 Free 12.3 (range 10-25)
TSH 2.31 (range 0.2-6.5)

I have dry skin, thinning hair, poor sleep, fatigue, brain fog and irritability. I’m almost 49 and thought this was all peri/menopause related. Possibly not!

Did they just do those three tests, or is it possible they did other tests and it's a follow-up to one of those?

They did lots of others - full CBC and Diff, fasting panel etc.

Off the back of these I was then sent for Ferritin, TPO and CRP

Tagging @DogInATent so you catch my reply 😊

So they're doing some follow-up. That's normal. Nothing to worry about.
Once they take an armful and start analysing it, they're bound to find something a little off to look at in a different way.

Your t4 is going towards the lower end but within range, I currently have the same t4 and menapausel as well and have the symptoms you mention.
