Thyroid Ranges

[corena7]

My daughter and I picked up our copy of our blood test today. We noticed that the ranges on our results for our TSH 0.3 - 5.0 and Free T4 7.9 - 16.0 were the same, but my daughter is underactive and I am overactive so how can the ranges be identical? How can this be correct?

The range is the same for everyone. It's the result that is important and where it falls within (or outside of) the range.

So what are your results?

Are you both diagnosed and on medication?

[corena7 in reply to SeasideSusie]

My results on recent blood test are TSH 2.21. 0.3—5.0.

FreeT4. 9.2. 7.9—16.0

VitaminD 72 . 50-75 FreeT3. 5.6. 3.8—6.0

B12. 335. 120—900

..Medication raised November 2019. to. Carbimazola 10mgs per day.

Was diagnosed in 2010 Hyperthyroid.1

Medication raised November 2019. to. Carbimazola 10mgs per day.

TSH 2.21. 0.3—5.0.

FreeT4. 9.2. 7.9—16.0

FreeT3. 5.6. 3.8—6.0

What were your results that prompted the increase of the Carbimazole to 10mg daily?

Your results are certainly no longer hyperthyroid.

I'm not au fait with treatment for overactive thyroid, but if you were hypOthyroid then your TSH would be too high and your FT4 too low.

Your Vit B is too low, need a unit of measurement to comment further, i.e. pmol/L, pg/ml or ng/L, plus a Folate result.

Can't comment on Vit D without knowing the unit of measurement, i.e. ng/ml or nmol/L.

Corena The ranges are what they expect a normal person to be. Ranges are like a ruler. The ruler stays the same size but is used to measure everything big or little.

For full Thyroid evaluation you and your daughter need TSH, FT4 and FT3 tested.

Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, with Graves’ disease (hyperthyroid) and Hashimoto’s (hypothyroid)

Ask GP to test vitamin levels

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Your daughter...Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Are you both on strictly gluten free diet?

If not ........Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and slowly lower TPO antibodies

While still eating high gluten diet ask GP for coeliac blood test first or buy test online for under £20, just to rule it out first

Assuming test is negative you can immediately go on strictly gluten free diet

(If test is positive you will need to remain on high gluten diet until endoscopy, maximum 6 weeks wait officially)

Trying strictly gluten free diet for 3-6 months

If no noticeable improvement, reintroduce gluten and see if symptoms get worse
