BH results

After my panic a couple of days ago trying to take the sample, all was ok :-)

These are my results:

CRP 1.20 <5.0 mg/L

Ferritin 104.9 20 - 150 ug/L

Thyroid Function

TSH H 4.32 0.27 - 4.20 IU/L

T4 Total I 64.5 - 142.0 nmol/L Insufficient

Free T4 L 11.70 12 - 22 pmol/L

Free T3 4.83 3.1 - 6.8 pmol/L


Anti-Thyroidperoxidase abs H 251.0 <34 kIU/L

Anti-Thyroglobulin Abs H 399.5 <115 kU/L


Vitamin D (25 OH) 80 Deficient <25 nmol/L

Insufficient 25 - 50

Consider reducing dose >175

Vitamin B12 413 Deficient <140 pmol/L

Insufficient 140 - 250

Consider reducing dose >725

Serum Folate 26.19 10.4 - 42.4 nmol/L

I'm currently taking 50mg levo and 12.5mg T3.

Immediate thoughts are I need to get back on the B12 supplements with a B complex but is there anything else I need to be doing?

Thyroid peroxidase and thyroglobulin antibodies are positive for autoimmune thyroid disease (Hashimoto's) which causes 90% of hypothyroidism. 100% gluten-free diet may improve symptoms and reduce antibodies.

High TSH and low FT4 indicate you are undermedicated and should increase Levothyroxine dose. FT3 4.83 is relatively good and increasing Levothyroxine should also increase FT3.

VitD 80 is in the replete 75-200 range. You should be fine until Oct-Apr when you should supplement 2,500iu D3 to maintain levels through the winter.

B12 is optimal around 1,000. Supplement 1,000mcg methylcobalamin with a B Complex vitamin. Folate is good.

Hi Clutter

Thanks for your help.

I'm coeliac so already gluten free.

Will try and persuade my GP to increase my Levo......I won't hold my breathe though. If I have no joy, do you know if it's possible to buy Levo? I've had to do that with the T3



Your TSH is over range and FT4 below range so you shouldn't have any trouble getting a dose increase. It is possible to buy Levothyroxine without prescription but it won't be the Levothyroxine you get on NHS.


Thanks Clutter, I'll try my GP :-)
