Blood test results

[erithstreet]

Hi i have recently had a blood test that says TSH 0.04. And T4 21. I have had an underactive thyroid for 16 yrs and its usually on the low side despite thyroxine. In April 2020 my T4 was 11 so drs advised me to up my dose of thyroxine to 200 mcg. But then i started feeling awful but put a lot of my symptoms down to menopause. I eventually had a blood test with the above results. But when i phoned for results i was told was in normal range so no further action. I always ask for a print out of results and it clearly states that patient may be taking too much thyroxine. And to have a repeat test in 3 months. No one at drs told me this . Surely its good practise to have advised me of this. Or is this still thought to be in normal range ? Sorry for long post

In order to make any accurate comment, please add the reference ranges for the test results, these will be on the print out. Ranges vary from lab to lab so we can't interpret your results without the ranges that came with them.

Do you always get same brand of levothyroxine

What vitamin supplements are you currently taking

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies

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 .

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)

Is this how you do your tests?

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

You may be on too much now. I would reduce your dose a little and see if you feel better.

How large was the increase in dose ? what was your previous dose. Maybe try reducing by 12.5 mcg /daily and see how it feels for a few weeks.

I agree , it would be good practice if gp's discussed with you the recommendations from lab , ( even though they are often incorrect in practice) , but it's normal for them to not mention anything if in their opinion it's 'normal ' for you, or they think it might be a 'one off'. Sometimes they do nothing , sometimes they ask you to have a repeat in a few months.

Very Very rarely do they do anything sensible like Ask YOU how you are feeling....Duh!
