Good afternoon,
I had a postnatal thyroid bloods check this week (baby is 5 months- and I was shocked to see TSH has come back at 0.01 (range 0.2-5). This was taken mid morning, no fasting, just a routine blood test. My levothyroxine dose has not been reduced since it went up to cope with pregnancy. I am guessing I am taking too much levo and need to see GP? My blood test has been “passed” as in I haven’t been called to see them, but that does look very low. They only did TSH so I know maybe I should ask for T3 T 4 bloods too? I should add I feel really good at the moment, apart from no sleep with baby!
To give a reference point, these were my levels at the start of December, Results were:
TSH 0.957 mIU/L (0.27 - 4.20
pmol/L)
FREE THYROXINE
17.3 (12.00 - 22.00
pmol/ L)
FREE T3 4.98
(3.10 - 6.80
IU/mL)
THYROGLOBULIN ANTIBODY
24.8 (0.00 - 115.00
IU/mL)
THYROID PEROXIDASE ANTIBODIES*83.7 (0.00 - 34.00)
Thank you!
