Latest blood test results

Hi all, these are my latest test results. I am currently taking 125mcg levothyroxine, 2000IU vitamin D3, vitamin c, b12, b complex, vitamin k2 and 200 MCG iron. My go has prescribed me an iron/folic acid pill.

Vitamin D 83 nmol/L

Serum iron 10.7 micromol/L 11.00-30.00

Serum folate 8.5 microg/L 3.00-20.00

Serum ferritin 39.1 microg/L 10.00-200.00

Vitamin b12 1031 ng/L 180.00-900.00

TSH 0.24 mU/L 0.30-4.20

T4 15.6 pmol/L 9.00-19.00

T3 4.1 pmol/L 2.60-5.70

All my thyroid results have gone down since my last test in January.

Any advice would be greatly appreciated.

  • Catpurple7,

    TSH usually goes up when FT4 and FT3 drop. Your results indicate 125mcg is an adequate dose as TSH is low, FT4 is close to top third of range, and FT3 is half way through range. If you are symptomatic there is scope to increase dose to improve FT4 and FT3. Read Treatment Options in thyroiduk.org.uk/tuk/about_... Email louise.roberts@thyroiduk.org.uk if you would like a copy of the Pulse article to show your GP.

    I would continue supplement vitD until May/June when natural sunlight should provide the vitD you need but you will need to resume supplementing Oct-April.

    Iron and ferritin are low but you are supplementing iron. Take 1,000mcg vitamin C with each iron tablet to aid absorption and minimise constipation.

    Folic acid will also boost folate.

    B12 is good because you are supplementing.

    Take vitD and iron 4 hours away from Levothyroxine.

  • Thanks Clutter that's really helpful, in regards to iron can I take 2 tablets together or do they need to be spaced apart?

  • Catpurple7,

    I'm not sure. Didn't the GP direct how you should take it?

  • I was thinking of taking an iron tablet along side the iron/folic acid tablet to try and increase my iron intake.

  • Catpurple7,

    I believe the folic in iron/folic tablet increases absorption but I don't know whether you should take another iron tablet with it or take it seperately.
