GP Print out of Thyroid test ?

I have another printout and this gives the ranges the lab uses when assessing my results. I have a question here... as they are mentioning this as Abnormal, highlighted by an exclamation mark. !! The (short) printout reads like this:

Values and Investigations (latest Value)

6-July-2017 ! Thyroid function test - (GSD157) - Abnormal -

No Action

! Plasma TSH Level <0.01 mU/L 0,30 - 4.20mU/L

! Plasma free T4 level 19.2 pmol/L 9.00 - 19.00 pmoI/L

Plasma free T3 level 3.8 pmoI/L 2.60 - 5.70 pmoI/L

Any help to explain would be much appreciated.

Annie-it's marked abnormal because TSH is suppressed and FT4 very slightly over range. However, not enough to cause alarm.

What is very obvious though is that your FT3 is far too low for you to feel well. It should be in the upper part of the range.

Your T4 to T3 conversion is poor. Good conversion takes place when FT4: FT3 ratio is 4:1 or less. Yours is 5.05 : 1.

What you actually need is a slight reduction in Levo and some T3 added.

AnnieC11,

The exclamation mark is flagging up abnormal results to your GP. TSH is suppressed because it is <0.01 and FT4 is mildly over range. Some GPs will reduce dose when TSH is suppressed but you aren't over medicated because FT3 is within range.

You. Eed to address why you are t converting by looking at Vit D. B12, folate and ferritin. They need to. E optimum so post results for guidance and in time they should make your conversion good. You may not then need T3 and your overall health will be better from getting things addressed. It can take. Little time to get them up to a good level though if. Wet low and if that's the xaae then some of your symptoms could be because of that

Thank you all for your replies. Very much appreciated. My next step is to get an private blood test done through one of the Labs suggested on here and I then hope to post the results on here. Hopefully they will point me in the right direction.
