Thyroid tests - new results after Levo change.

[mids_thyman]

I posted recently because I changed my own Levo does (as my doctor wouldn't). My new results, 8-weeks later are now in:

I have an update at the 8-week mark I've had my levels retested. My new results are:

TSH levels 0.98 mu/L (normal range 0.27 - 4.2 mU/L)

FT3 levels 4.9 pmol/L (normal range 3.1 - 6.8 pmol/L)

FT4 levels 19.3 pmol/L (normal range 12 - 22 pmol/L)

Vitamin D: Your result is 81 nmol/L - replete

It looks as though the TSH is the only one that has seen a notable change. Do these look OK on my new dose?

Frustratingly some of the results weren’t done as there was a lab error so I need to retest:

• HB, Ferritin, TSAT, Active B12, Folate

For info my previous test results were:

TSH level: Your result is 2.39 mu/L (normal range 0.27 - 4.2 mU/L)

FT3 level: Your result is 4.8 pmol/L (normal range 3.1 - 6.8 pmol/L)

FT4 level: Your result is 19.4 pmol/L (normal range 12 - 22 pmol/L)

Free T4 (fT4) 19.3 pmol/L (12 - 22) 73.0%

Free T3 (fT3) 4.9 pmol/L (3.1 - 6.8) 48.6%

Your FT3 is getting close to optimal. Your FT4 could be a little higher. Suggest dose increase of 12.5mcgs or 25mcgs alternate days.

Start a new post when you get the vitamins retested.

Optimal is not a number, it's how you feel. You cannot possibly tell if someone's FT3 is optimal just by looking at a blood test result.

previous GP result on 50mcg (October , levo taken on day of test) :

TSH 4.2

FT4 13.2 (range ?)

you got MMH result 2 mths ago , still on 50mcg : (24 hrs after last levo)

TSH: 2.39 (0.27 - 4.2)

FT4: 19.4 (12 - 22)

FT3: 4.8 (3.1 - 6.8 )

GP wouldn't increase even though they were looking at their own TSH result of 4.2, saying symptoms not relevant , .. so you (quite reasonably) increased yourself .

what dose did you increase to ?

now after 8 wks : (24hrs after last levo)

TSH: 0.98 (0.27 - 4.2)

FT4: 19.3 (12 - 22)

FT3: 4.9 (3.1 - 6.8) ..... (interestingly fT4 / fT3 haven't really moved on the higher dose , but TSh has dropped significantly)

How do you feel after 8 weeks on this dose ?

while your TSH is still in range (just) it might be an idea to get retested by GP on this dose , hopefully if TSH is in range on their test , they may agree to increase your prescription to whatever you are taking (assuming you feel better now than you did on 50mcg)

strategically , i do not think it is a good idea to increase your dose any further AT THIS POINT ~ if you do , your TSH will likely go below range giving GP the opportunity to say 'told you so' and they will definitely not agree to increase your prescription.

Also ~ if you have felt any improvements on higher dose in the first 8 weeks , it is reasonably likely that these improvements will continue steadily if you stay on that dose for another month or so.

it is also possible that your TSH might come back up a little bit if you wait another month or so before testing with GP,, but thats very much a 'suck it and see' issue , it might, or it might go lower , no way to know for sure.

So you are now taking 75mcg every day

Have you had prescription updated to reflect this?

Come back with new post once you get other vitamin results
