I went to see an endocrinologist who went over my test results.
My results back in 2009 (was tested due to period changes)
Free T4 16.5 pmol/l (9.8 - 23.1)
TSH 0.73 mu/L (0.35- 5.50)
My test results in November 2017 were
TSH 3.41 mu/L (0.30- 4.40)
Free T4 level 10.9 pmol/L (9.0-19.1)
My results in February 2018 were
TSH *4.57 mIU/L (0.27 - 4.20)
FREE THYROXINE (FT4) *11.4 pmol/L (12.00 - 22.00)
TOTAL THYROXINE(T4) 73.4 nmol/L (59.00 - 154.00)
FREE T3 4.8 pmol/L (3.10 - 6.80)
THYROGLOBULIN ANTIBODY <10 IU/mL (0.00 - 115.00)
THYROID PEROXIDASE ANTIBODIES 11 IU/mL (0.00 - 34.00)
He did some explaining but I've forgotten what he said (suffering with memory issues at the moment), about what certain levels mean if they go up and down.
He said that it was 'odd' that my T3 was good, but my TSH was rising. What does that indicate?
He's sending me for blood tests to do further monitoring.
I don't have Hashimotos as I don't have any antibodies, and he says it's unlikely to be a pituitary issue. What else could be causing this? (He's also looking into the possibility that I'm going through premature peri-menopause as well)
Could someone explain what this all means, please?
