T4 range normal or not?

[hardakersarah1971]

Hi,My last NHS thyroid blood test came back Normal Range but on other thyroid sites My T4 is high? I have Hypothyroidism and take 100mg Levothyroxine,Does this seem correct? My result was THS 2.1 T4 9.8

Ive been battling for years to get the 6 stone i put on since having the diognosis 10 years ago! Kind thanks Sarah.

Please post your results with the reference ranges. We can't tell what your results mean without those. Usually in brackets after the result.

All thyroid tests should be done as early as possible in morning before eating and drinking anything apart from water and last dose levo 24 hours before test

Essential to test vitamin D folate ferritin and B12 too

Guidelines on dose by weight is 1.6 MCG per kilo of your weight

Dose should be increased slowly upwards in 25mcg steps

What do you mean by "other thyroid sites"?

Each lab has it's own reference range, you can't use the range from one lab with results from a test done by a different lab.

My result was THS 2.1 T4 9.8

Are these your NHS results? What are the ranges?

Is that Total T4 (TT4) or Free T4 (FT4)?

There is nothing high about that T4 as the ranges we see here for FT4 are 7-17, 9-19, 11-23, 12-22 and others, No FT4 range, private or NHS, has ever had an upper limit so low that 9.8 would be classed as high.

Have you done the Medichecks test yet that you were asking about last week?

But what are the other thyroid sites you mention and what makes you say your T4 of 9.8 is high?
