To wonder if my blood test results were actually low?

[Hogwartsian]

For the last decade I have struggled with fatigue, depression and anxiety. I sleep about 12 hours across the day. I wake up every morning like I haven't slept for a week. I'm 30 years old now, a woman and 5'2.

When I was 25, I got my bloods done and it all came back normal range and the GP waved me goodbye. However I found my results last night and I wonder what you all think. I'm getting mixed results on the internet as to what is actually the acceptable range! Can anyone with experience in this help me?

Thyroid serum TSH 3.358 mu/l
Serum free T4 8.3pmol/l
Ferritin 28 ug/l

Are they actually normal?

Or not necessarily low, but not entirely normal/a concern.

This was 5 years ago? If you’re still having problems then you need to return to your GP

Your ferritin was a bit low. You do need to go back to your GP.

Your thyroid looks like borderline hypothyroidism and it would have been best to follow up with a blood test after three months.

Your ferritin looks like it's bumping along towards the bottom of normal.

Back to the GP and advocate hard, get copies of results and compare to reference ranges. Note your previous results and lack of follow-up and how you have continued to feel exhausted. If you get nowhere can you afford to see an endocrinologist; couole of visits £500 to £600. They might accept recent full bloods. A letter from them based on your resulys might make the GP take you seriously.

I am definitely going to go and get new bloods done and compare. I just thought the fatigue must be a result of the antidepressants I take. But maybe it's not.

I'll probably get shot down for this, but I have had bloods done in the last few days and couldn't make head nor tail of the medical jargon on my NHS app notes, so I copied and pasted it into an AI search to interpret it for me. It looks like I'm quite anaemic (low ferritin and iron) although I feel fine. I'm not suggesting for one minute that folk should rely on AI for a diagnosis but if you want a rough idea what you're dealing with it might be worth a try, then get booked in with your GP. I've got an appointment with the GP to go through my results properly on Friday.

Stop using 5 year old bloods and maybe go see your gp.
and no you don’t need an endocrinology as suggested at this stage.

@UncharteredWaters I said, if the op gets nowhere with the GP.

5yo blood test results are irrelevant really - if you’re struggling you need to go back to your GP and ask for help. My anaemia wasn’t picked up on by routine bloods - I was sat at the bottom of normal so I was dismissed originally - I had to push and see another doctor before they would re-check everything.
