Within range bloods - can someone confirm please?

[Barny12]

Hi all,

After being diagnosed with atrial fibrillation five years ago and an ambiguous NHS blood test showing possible hypothyroid symptoms I decided, as my diet is mostly plant based, to take a vegan multivitamin/mineral including iodine. I had a private thyroid test done a few months later which appeared to be within "normal" parameters apart from ferritin.

I've just had another test to see how things are, and again all seem to be within parameters, apart from the B12 (which I supplement). Can someone confirm please?

Thanks very much

* Vitamin D (25 OH) 70 (50 - 200 nmol/L)

* Magnesium 0.96 (0.66 - 0.99 mmol/L)

* CRP <0.60 (<5.0 mg/L)

* Ferritin 51.80 (30 - 400 μg/L)

* Serum Folate 38.10 (8.83 - 60.8 nmol/L)

* Active B12 >150 (37.5 - 150 pmol/L)

* TSH 1.86 (0.27 - 4.20 mIU/L)

* Free T4 15.0 (12.0 - 22.0 pmol/L)

* Free T3 4.7 (3.1 - 6.8 pmol/L)

* T4 Total 86.7 (66 - 181 nmol/L)

* Anti-Thyroglobulin Abs 14 (<115 IU/mL)

* Anti-Thyroidperoxidase abs <9.0 (<34 IU/mL)

* Cortisol (Random) 450.0 (73.8 - 507.0 nmol/L)

* Vitamin D (25 OH) 70 (50 - 200 nmol/L)

Too low. Should be more like 100

* Magnesium 0.96 (0.66 - 0.99 mmol/L)

Irrelevant. The results are not reliable with magnesium. Not worth testing.

* Ferritin 51.80 (30 - 400 μg/L)

Too low. Should be over 100.

* Serum Folate 38.10 (8.83 - 60.8 nmol/L)

* Active B12 >150 (37.5 - 150 pmol/L)

Good.

* TSH 1.86 (0.27 - 4.20 mIU/L)

On the high side.

* Free T4 15.0 (12.0 - 22.0 pmol/L) 30.00%

Too low. Should be more like 50% through the range.

* Free T3 4.7 (3.1 - 6.8 pmol/L) 43.24%

Too low. Should be just slightly lower in range than the FT4. The fact that it is higher is an indication that the thyroid is failing.

* T4 Total 86.7 (66 - 181 nmol/L)

Irrelevant.

* Anti-Thyroglobulin Abs 14 (<115 IU/mL)

* Anti-Thyroidperoxidase abs <9.0 (<34 IU/mL)

Negative, but that does not entirely rule out Hashi's.

* Cortisol (Random) 450.0 (73.8 - 507.0 nmol/L)

What time was the blood draw for this test? Cortisol levels change throughout the day - as does TSH.

It's not just about being in-range, it's about being in the right place within the range. All your results are in their ranges, but that does not make them normal for you.

I decided, as my diet is mostly plant based, to take a vegan multivitamin/mineral including iodine.

Multivits are a very bad idea - iodine is an even worse idea! There are many things wrong with multi-vits - such as containing iodine! But if they also contain iron, that will block the absorption of the vitamines and a lot of other things, too. There is never enough of anything to treat a true deficiency, and usually the cheapest - i.e. least easily absorbed - ingredients. Best to take supplements individually according to your need.

Thanks for the analysis - I'm a newbie round here, though so could you let me know what all this means? Am I hypothyroid? Or is this something I can tweak with a change of diet/vitamins or do I need meds? Can't imagine my GP will be interested as the results seem within range...
