Your thyroid antibodies are within range meaning you don't have an autoimmune thyroid condition and your TSH is normal, however, your thyroid isn't working very well as your FT3 is very low.
As you have other symptoms such as hair loss, have you had your vitamin levels tested? Your thyroid won't function very well if they are too low. Are you on any medication that could interfere with thyroid function? Are you very under or overweight or on a very restrictive diet?
As both your FT3 and FT4 are low there may be other things to consider such as whether your pituitary gland is functioning well. I don't know much about central hypothyroidism but perhaps someone here will have a look at your results and see if it's a possibility.
Thank you Nanaedake. Nope, not on any medications although I am taking a vit D supplement as that came back as low. Normal weight, although have difficulty keeping this down as also have PCOS
I think PCOS can have an interraction with the thyroid gland but it's not something I know anything about. I know others have written more about it on this forum so you could do a search. Hopefully someone will be along soon to answer your questions more fully.
Post your vitamin D test result along with the lab range and the amount of supplement you're taking and people will let you know if your supplement is sufficient. If you have any othr vitamin results post those too as docs will often say results are fine even though they are just bumping along the bottom of the NHS range and it won't make you feel well.
You should most definitely consider Central Hypo. But it's something that your doctor has probably never heard of.
Central hypo is when the problem lies with the pituitary or the hypothalamus, rather than the thyroid itself. Not enough TSH is being produced to stimulate the thyroid to make thyroid hormone, so the FT4 and FT3 levels drop lower and lower, whilst the TSH stays the same, instead of rising. See if you can research it a little, so that you know a bit about it, then suggest it to your doctor. Ask him to refer you to an endo. It's very important to know if you have central hypo, because it will affect other hormones, too. 
Young daughters test results. Can anyone confirm they are ok?
