Iron test results advise please!

[Bluecat77]

Hi,

Thanks for the great advice on my last post.

Latest Thyroid results:

TSH 0.824 (0.27 - 4.2)

FT3 4.2 (3.1 - 6.8)

FT4 15.2 (12 -22)

TPA antibodies 13.1 (0 -34)

Thyroglobulin antibodies 285 (0 -115) HIGH

Since my last post I have seen a private thyroid GP and have been prescribed T3 I took 15mg per day for 3 months and although it lowered my TSH levels the T3 levels remained the same and my T4 levels actually decreased! So my T3 was upped to 30mg per day recently (split into Am & Pm 15mg doses) T4 remaining at 100mg in the morning.

I have been taking Vit b complex, magnesium & Vit D spay daily and my levels are now starting to look better.

No change in symptoms ( lethargic, exercise intolerance, cold hand & feet, brain fog)

I have had the results back from a iron test and wondered if I need to supplement, although the most results are within range they are at the low end.

all bloods taken around 9am and no medication on the morning of tests.

Hopefully the increase in T3 may start to kick in soon.

Thanks again.

TSH 0.824 (0.27 - 4.2)

FT4: 15.2 pmol/l (Range 12 - 22)

Ft4 only 32.00% through range

TPA antibodies 13.1 (0 -34)

FT3: 4.2 pmol/l (Range 3.1 - 6.8)

Ft3 only 29.73% through range

Thyroglobulin antibodies 285 (0 -115) HIGH

Were these results AFTER last increase to 30mg per day recently (split into Am & Pm 15mg doses) T4 remaining at 100mg in the morning.

Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test

On T3 - day before test split T3 as 2 or 3 smaller doses spread through the day with last dose 8-12 hours before test

possibly need increase in levothyroxine to 112.5mcg daily or even to 125mcg daily

Iron results:

Serum iron : According to the rt3-adrenals link rt3-adrenals.org/Iron_test_...

• 55 to 70% of the range

• higher end for men

Given that your result is 35% through the range and you are female I would say your result is a little on the low side.

TIBC (total iron binding capacity) or Transferrin

• Low in range indicates lack of capacity for additional iron

• High in range indicates body's need for supplemental iron

Your TIBC is 46% through the range and your transferrin is 14% through the range, both of which are in the lower half of the range. This suggests that you don't have the capacity for more iron.

Ferritin : 122

Optimal for ferritin depends on source. Some people aim for mid-range which is 96 for your range. Other suggestions are 90 - 110 ng/mL .

So over all I would say that although your serum iron is very slightly below optimal you don't have capacity for more iron via a supplement and added iron rich foods would be the way forward.

Thanks for your help Jaydee, I’ll see about adding some iron rich foods

Actually well spotted but I dont think it will make any difference in what I recommended.
