I was diagnosed with a under active thyroid 10'years ago next month and I've just started looking into it as I've always struggled with my weight and never felt right I have been on 175 mg for the past 3-4 years.
My most recent blood tests are below and I'm not sure how to read them I am on levothyroxine and I took my tablets approximately 14 hrs before taking the blood test:
TSH SERUM 0.03
FREE T3 SERUM 4.7
T4 SERUM 21.00
B12 SERUM 483
VITAMIN D 44
SERUM FOLATE 8.4
Any help on the above would be greatfully received .
