Your TSH is at a good level but FT4 is only 39% through range which is low. When on Levo only, the aim of a treated hypo patient generally is for TSH to be 1 or lower with FT4 and FT3 in the upper part of their ranges if that is where you feel well. So your low FT4 suggests you may be undermedicated.
Dr Toft, past president of the British Thyroid Association and leading endocrinologist, states in Pulse Magazine (the magazine for doctors):
"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l. In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l. Most patients will feel well in that circumstance. But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l. This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l).*"
*He recently confirmed, during a public meeting, that this applies to Free T3 as well as Total T3. You can obtain a copy of the article by emailing Dionne at tukadmin@thyroiduk.org print it and highlight question 6 to show your doctor.
However, FT3 and thyroid antibody tests are also important.

Remember that I'm not medically trained but these are just my thoughts on the following:
Cholesterol 6.8 (3.1-6.5)
This may be raised due to possibly being undermedicated as high cholesterol is a symptom of hypothyroidism.
Cholesterol LDl. 4.2 (4.2)
Presumably there is a bottom of range also and you've just given the top of range, in which case you are right at the top. Same thoughts apply as given for the above cholesterol result.
None help cholesterol 5.20
I don't know what that is.
Serum triglyceride levels 2.2 (0.2-2.0)
High triglycerides can be a sign of hypothyroidism, certain medications can cause high triglycerides too.
White blood count 5.1 (4.5 -11.0)
This is at the lower end of the range, can sometimes be low due to infection.
Lymphocyte count 1.4 (1.0-4.8)
This is at the low end of the range. I don't have any information about this, but maybe it's something your GP might want to check another time.
Lymphocytes are a type of white blood cell so these results are possibly linked.

Your Vit D, B12 and folate were covered in replies to previous posts.
Do you have a result for ferritin? Or an iron panel?
Thank you so much it kind of confirms what l have been telling them.
no ferritin results.
When l was seen this morning she was very dismissive of me said oh your disputing the finding s are you ?
I can't tell what's going on its all very confusing !
Well more so for me l replied, after explaining that they had taken me from 200mg to 125mg ,but l still felt bad she has said let's look at your bloods again fasting this time !
To see if anything else is going on as all your results are normal.
Your serum iron level is pretty good at 53%, optimal is 55-70% with the higher end being for men. But that is only one part of the iron panel, you need ferritin as well. Was there TIBC and transferrin saturation?
Why was your Levo reduced from 200 to 125mcg? Do you have the results that prompted that?
Have you ever had thyroid antibodies tested - Thyroid Peroxidase and Thyroglobulin?
I can't see that on any of the information that l have, l can ask for them next time l go for bloods ,never had thyroid antibodies tested that l know of, should l request this.
Today she told me that my thyroid was toxic and that's why they reduced it and stressed that it was dangerous to have too much thyroxin, l felt like a could have exploded , GP 29 mins late for my double appointment then fobbed my off with blood even after l asked question about water retention and arthritis!
