Blood test results

I had my blood test on Monday. The nurse asked for antibodies to be done but they haven’t been done. The blood test was taken at 2.30 pm (only one they could give me). I did fast and hadn’t had my tablets that I usually take at 7.30 am.

So I had my thyroxine increased from 150 to 175! In March TSH was 0.05, (0.30-5.00). T4 was 17.8 (11-22) and T3 was 4.8 (3.10-6.80).

I feel a whole lot better on this higher dose. I put off the repeat blood test because I was worried about gp decreasing it again.

I have a telephone consultation for Wednesday.

Can I justify remaining on this dose? Why is the result so different with just 25 increase?

Any feedback and advice would be welcomed.

Your Vitamin D is very low. This can hinder Thyroid hormones being used. So you need to supplement to improve. GP could/should prescribe but you are likely better off self supplementing. Aiming to improve to around 100nmol.

GP should prescribe 2 x 800iu tablets be day

But Vitamin D mouth spray by Better You is good as avoids poor gut function. Widely available. Suggest you try 2000iu daily for 2-3 months and then retest. It's trial and error what dose each person needs. Once you Improve level, very likely you will need on going maintenance dose to keep it there. Retesting twice yearly via vitamindtest.org.uk

B12 and folate are also quite low. (GP won't agree.) So you might benefit from self supplementing a good quality daily vitamin B complex. One with folate in

If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results

Only make one change at a time or add one supplement at a time and wait 2 weeks to assess any improvements.

Essential to test both TPO and TG antibodies

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.

Thank you for your reply. That’s great advice and I will get some vitamin B. Hopefully the GP will give me some Vit D and I will read the attached information.

I have sat and read these links this evening- they are very informative. Could you recommend a brand for good quality supplements for the magnesium, K2, and other recommended supplements including the B complex you suggested as I have never bought any supplements before I like the idea of pickling veg for vit K but probably would never keep it up! Thank you.

SlowDragon I would be grateful for you advice. I have bought Solgar Vit B complex ‘100’ extra rich potency but it has folic acid ( is this the same as folate?). I have also bought ‘better you’ Vit b12 oral spray. The person in the health food shop said I could take both?

I also bought ‘better you’ Vit D 3000 iu plus K2. 75 ug. Could you advise me on how much magnesium I should add and do I need to take calcium alongside these?

Thank you.

Not really, you are overmedicated. Considering that your last dose of Levo was 7.30am the day before, and your blood was drawn at 2.30pm, that's 31 hours, your FT4 and FT3 are both over range.

It's possible that a 12.5mcg increase may have been enough.

It's also possible that you have raised antibodies which means Hashi's.

Thank you. Your reply makes perfect sense and I think I was just burying my head because I don’t want the symptoms I was having before the increase to return. My joints were so bad I thought I was menopausal but the increase dose sorted me out and I have felt great. Putting my sensible head on with your advice has made me realise that other issues arise by being over medicated too. Thank you for your advice.

I would suspect Hashi

You need to ask GP to test antibodies or test privately

I will ask again. The nurse did write it on the form but as in my last post, she was confused as to which test was needed and possibly put the wrong thing on the form. If he cannot do it I will do the private test. Thank you

Agree with all the above.. Antibody attacks (Hashi's flare-ups) can temporarily raise T4 / T3 and suppress TSH. Lowering your dose long term may not work.

On the other hand it could just be over-medication. This is why you must get those antibodies tested .... your nurse sounds switched on.

N.B. Going gluten / casein free can reduce antibody attacks as many of these peptides make it through the 'leaky gut' wall triggering an autoimmune response.
