Test results for teen - opinons?

[minxabroad]

The following are blood test results for my teen daughter over the past year. Opinions appreciated as gp says they are normal and nothing should be done about them.

We have tried to get them to test the antibodies and T3 several times but they have not done so. Switiched to a new GP this week and hoping for better treatment.

Results include some tests not directly thyroid related just in case there is an indirect indication of something:

April 2017

------------------

Serum free T4 9.6 pmol/L - (7.9-13.3)

Serum TSH "Above Range" 5.80 mU/L - (0.9-3.11)

Serum creatinine level "Below Range" 52 umol/L - (53-97)

Serum C reactive protein "Above Range" 8mg/L -(0.0-4.0)

Serum Ferritin "Below Range" 9ug/L - (11 - 307)

Serum 25 hydroxy Vit D3 "normal" 58 nmol/L - (Vit D>50 is sufficient for most people)

The GP did not want to give her Iron and asked her to rely on the iron in her diet but eventually did give in to giving her iron tablets. GP suggested she was tested again in 6 months time but I was insistent she be checked again sooner than that so she was tested again in June. They only tested several things, not the FBC.

JUNE 2017

----------------

Serum free T4 "normal" 11.4 pmol/L - (7.9 -13.3)

Serum TSH "Above Range" 3.58 mU/L - (0.9 - 3.11)

Serum C reactive protein "Above Range" 7 mg/L - (0.0-4)

September 2017

--------------------------

Serum TSH 5.24 mU/L (0.38-5.33) This is now in range as the reference range for Serum TSH was changed from August 2nd but obviously would have been ABOVE RANGE if it had been a result in either of the previous months tests.

I suppose there is not much to say other than she needs the antibodies and the T3 checked? What say you?

Minxabroad,

TSH above range isn't normal. As your daughter has more than one abnormal TSH her GP should have considered making a diagnosis of subclinical hypothyroidism as FT4 is normal. Ask her GP to check thyroid antibodies to confirm or rule out autoimmune thyroiditis (Hashimoto's). Fluctuation in TSH and FT4 is usually due to Hashimoto's. Her last TSH result was in range, just. It would not have been above range in previous months because the lab analysis machine will have changed as that is why the range has changed. FT3 is rarely tested in primary care, especially when TSH is high because it is very unlikely FT3 will be high when TSH is high.

Creatinine mildly below range is not usually a matter for concern - labtestsonline.org.uk/under...

C Reactive Protein is an inflammation marker. Your daughter's is high which indicates inflammation somewhere in the body. Having positive antibodies for Hashimoto's can elevant CRP.

Ferritin was deficient in April and that can indicate iron deficiency anaemia. You've not included ferritin, iron or FBC from June. Ask her new GP to recheck ferritin and if it is still deficient to do a full iron panel and full blood count.

VitD 53 is sub optimal. VitD is optimal 100 - 150. I would buy 5,000iu D3 softgel capsules to take daily x 8 weeks then reduce to 5,000iu alternate days and retest late March. If you buy on Amazon please use the affiliate link healthunlocked.com/thyroidu...

If your daughter is prescribed Levothyroxine she should be careful to take it 4 hours away from iron and vitamin D.

Thank you very much.
