hi just had blood test back still don’t understand

My t4 was 18.3 and tsh 0.01

Can anyone work it out

The TSH (thyroid stimulating hormone, from the pituitary) is low. Which doctors interpret as the pituitary telling thyroid there is too much thyroid hormone.

The TSH isn’t reliable you need to look at FT4 & FT3.

If you take lio (T3) the TSH very frequently goes very low.

What is the range on FT4 (is on range by most ranges) was FT3 tested? It should be as you take lio.

How much levo & lio do you take?

Do you feel well?

Your doctor may reduce your replacement dose on these results (they focus on TSH), but you may not be over replaced.

Was the test in morning? Did you fast, how long was test after taking replacement?

Hi I take 30 mg t3 100 mg in 5 ml thyroxine I’m taking teva was taking zenteva had side effects on that pharmacy say can’t get mercury pharma Had blood test at 8 10 am not got the t3 results back yet

What about timing of dose before test? If you took replacement prior to test it might show a higher result.

Do you feel over replaced or do you think level is right?

Once you have range and FT3 results you can make a better judgement.

Don take medication before test and only water

Looking at your previous post you’re on T3 …..and presumably on levothyroxine too

How much levothyroxine

How much T3

Do you always get same brand levothyroxine and same brand T3

Just testing TSH and Ft4 is completely inadequate

You will need to test privately

Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine or T3

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.

Very important to test vitamin D, folate, ferritin and B12 at least once year minimum

Do you have autoimmune thyroid disease

About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies

Autoimmune thyroid disease with goitre is Hashimoto’s

Autoimmune thyroid disease without goitre is Ord’s thyroiditis.

Both are autoimmune and generally called Hashimoto’s.

Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis)

20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis

In U.K. medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)

Recommended on here that all thyroid blood tests early morning, ideally before 9am and last dose levothyroxine 24 hours before test

Day before test split T3 into 2 or 3 smaller doses spread through the day…..last dose T3 approx 8-12 hours before test

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
