First time posting so a little information I am a 28 year old male with hypothyroidism symptoms, not diagnosed with anything.
Got my results but I am unsure what they mean or if I need to do anything, I'll post them with the values included and ranges and hopefully someone can help.
Serum TSH Level - 0.34 mu/L [0.35 - 4.7]
Serum free T4 level - 9.0 pmol/L [7.8 - 21.0]
Serum Ferritin Level - 106 ug/L
Serum Folate level - 11.1 ug/L
Serum vitamin B12 - 241 pmol/L [115.0 - 1000.0]
I was also high on bilirubin levels and alanine aminotransferase level (ALT) not sure if they matter.
Any advice would be greatly appreciated.
I just need to know if there is anything I need to do or move onto looking at other things?

Your results are suggestive of Central Hypo - just a pity that you don't have the FT3, but your FT4 is only 9.09% through the range, but your TSH is very low.
Central Hypo is when there is a problem with the pituitary (Secondary Hypo, where the pituitary cannot secrete enough TSH to stimulate the thyroid) or with the hypothalamus (Tertiary Hypo, where the hypothalamus cannot secrete enough TRH to stimulate the pituitary), rather than the thyroid itself (Primary Hypo).
Unfortunately, as doctors are only trained to looke at the TSH, they rarely pick up on Central Hypo, and need a nudge from the patient himself. You need to see an endo for further investigations.
It's really not surprising that you have hypo symptoms with such a low FT4.
Thank you very much for your helpful information, I think my next step will be to see my GP and insist on seeing an endo, I will use your information as reference.
For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12
Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies
Ask GP to test vitamin D and thyroid antibodies
Your B12 is rather low
You may need to get full Thyroid testing privately as NHS refuses to test TG antibodies if TPO antibodies are negative
Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .
Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies
Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random
Cheapest option for just TSH, FT4 and FT3 £29 (via NHS private service )
Some hints re getting a blood test for thyroid hormones:-
The very earliest appointment, fasting (you can drink water) and if taking thyroid hormone replacements allow a gap of 24 hours between last dose and test and take afterwards.
greygoose has given an excellent response.
Your B12 is too low and is more a pro-hormone than a vitamin and has an important function in our body. We can develop problems later in life and you must get checked in case you have Pernicious Anaemia which can cause serious symptoms if untreated, or some develop dementia.
There's also a PA section in healthunlocked, so I'd post on there as well.
