Can someone help me with my results please

[Mickdondan]

Serum TSH levels 0.9 mU/L 0.35 - 5.00

Serum Free T4 level 21.7 pmo1/L 11.0 - 23.0

I have been diagnosed with underactive thyroid for over 10 years but can’t understand my blood results. Could anyone please translate these for me please. I’m 52 year old female. Always tired. Hair is thinning. Test was taken first thing but I did take my daily 75mg as I’ve never been told not to. VitaminD levels are fine.

Was test done early morning, ideally just before 9am, only drinking water between waking and test and last dose levothyroxine 24 hours before test

How much levothyroxine are you currently taking

Do you always get same brand levothyroxine at each prescription

Looking at your forum name are you male?

Approx age and weight

And …..how do you feel

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

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

Also both TPO and TG thyroid antibodies tested at least once

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

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

What vitamin supplements are you taking

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 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

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

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

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