My daughters thyroid test results

[TiredMummy]

Hi all,

I posted on here a while ago about getting a thyroid blood test for my 13 year old daughter as she was finding it difficult to concentrate in class. I have Hashimotos so I just wanted to rule it out.

The good news is her results to my eye look ok, but would be grateful for any comments:

TSH - 0.70 (0.27-4.2)

Free thyroxine- 14.4 (12.0-22.0)

Free T3 - 6.0 (3.5-7.7)

Thank you x

In 2-3 months i would retest including thyroid antibodies, vitamin D, folate, B12 and ferritin

Make sure to test early Monday or Tuesday morning

I would look to test ferritin, folate, B12 and vit D as a next step, as there seems nothing of concern in her current thyroid test. Could your daughter’s tiredness be linked to puberty/ menstrual cycle?

Hi Buddy,

I had some tests done for her very recently on the NHS:

Vitamin D - 48 (30-250)

Folate - 12.4 (3.00-20.00)

Serum iron - 22.1 (11.00-30.00)

Serum ferritin - 39.2 (30-336)

Serum transferrin - 2.9 (1.80-3.60)

Serum B12 - 234 (180-900)

Serum potassium- 3.7 (3.50-5.00)

TSH - 0.64 (0.30-4.20)

Free T4 - 10.9 (10.00-17.00)

To my eye her ferritin looks low but I don’t understand iron tests really and her serum iron level looks more promising particularly as she’s turned vegetarian. Her vitamin D looks low and also B12 & potassium are on the low side. Her T4 looked low to me which is why I had the private test done so I could see the T3.

I'd say her vitamin D is a bit low and it's worth getting an active B12 test done too to compare the two. My bones hurt when my Vit D was 48, which went away after supplementing. Does she have any other symptoms?

[TiredMummy in reply to Mixteca]

Thanks, her only symptoms really are that she finds it difficult to concentrate in class so this could be a number of things and indeed a combination of things. I will seek advice on the vitamin front for now.

I would consider supplementing D3/k2, especially in Winter months. I find the ‘Better You’ spray very easy to use.

I will tag humanbean re low ferritin advice, as she has some very useful links.

[TiredMummy in reply to Buddy195]

Thank you Buddy, I will look that spray up!

I would not rule out thyroid problems yet. Her FT4 is rather low but her FT3 is over mid-range. That, in itself us unusual. I would say keep testing.

That said, was this a private test? Did the company know she's only 13? Ranges might be different for her age group.

Did you get both antibodies tested?

[TiredMummy in reply to greygoose]

Hi Greygoose, yes this was a private test and the requesting doctor certainly knew her age but I’m not sure if the lab knew but I can find out. I didnt get antibodies done. I had a thyroid NHS test done before this and the results prompted me to get a private test done so I could see her T3 levels. These are the results from the NHS test which was done 15th September:

TSH - 0.64 (0.30-4.20)

Free T4 - 10.9 (10-17)

The test was taken at the doctor’s surgery at 9:40am. Her T4 looked on the low side to me which is why I wanted the T3 test as a follow up.
