Hello wonderful people,
Following a thyroid and vitamin blood test with Medichecks in May this year, my GP increased my Levo from 75mcg to 100mcg (yaay). I have recently had an NHS blood test and was tested for TSH...... T4 AND T3 .... (another yay). Not sure how to interpret the results and was hoping you kind, knowledgable lot could help me out.
Here are the Medichecks results from 24 May 2022:
TSH 1.28 (0.27-4.2) 25.7% through range
FT4 17.3 (12-22) 53% through range
FT3 3.94 (3.1-6.8) 22.7% through range
Here are my results from 18 August 2022:
TSH 0.23 (0.2-5.5) -1.35% through range
FT4 16.5 (12-22) 45% through range
FT3 4.2 (3.1-6.8) 29.73% through range
I followed the pre-blood test advice given here for both tests. I did actually do a fasting test for the NHS test as well as the Medichecks, not sure if that was necessary thinking about it. After receiving excellent advice about vitamins from Seaside Susie in May, I now take Thorne B complex, D3, D2 MK27, magnesium spray and get selenium from Brazil nuts .... grown in selenium rich soil - another good nugget of information gleaned from this site!!
Symptom wise, I feel better now than I did in May, however the negative value of my TSH in August looks scary. I'm sure I've read that the FT3 should be 65% through range and FT4 should be 50% through range, which I'm not achieving at the moment.
So what I'm asking is - do I worry about the negative TSH? Do I need to do something to increase my FT3 and FT4 ranges? Oh and is the advice to fast prior to a blood test for TSH,T4 and T3?
Much appreciate all the help this forum has given.
