How much levothyroxine are you taking and which brand
How long on this dose
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
I’m taking 100mg of levothyroxine (Accord) I have been taking this for a couple of years now.
Last time my Vitamin D was tested I was over range,My iron levels are always on the low side but unable to take supplements although I do try and have iron rich foods.
I take theMagnesium supplement Floradex liquid formula 20ml.
Test was done before 9am fasting water only but levothyroxine taken at 10pm the previous evening.
Last dose levothyroxine should be 24 hours before test
next test
If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test
If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal
Okay I will ask the GP to test iron and ferritin levels I’m just worried in case she tries to reduce my medication,I’m new to the surgery and she doesn’t know me well.
Hi I’ve always had high platelet count usually around 650 ish also high basophil & eosinophils count. GP’s response has always been “we know yours is always high”.
I think they said inflammation due to RA. I’m interested to know how you get on.
Well she wasn’t bothered about the high Basophil or Platelets,I am having more Blood tests and she will keep an eye on them but thinks I may need an increase in Thyroxine and has agreed to test my iron and Ferritin levels ,She agreed my T4 result were probably a false high.
So still waiting until after next results but at least she listened to me.
Thanks. It’s strange they don’t seem bothered they are raised don’t you think? I’m glad they are doing more blood tests though. And it’s good to be listened to. Everything is a waiting game unfortunately
Thank you Otto 11,yes it is strange but hopefully in the long run we will get to the bottom of it and if I can get an increase of my Levothyroxine I think I will feel much better.
With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a separate B12 supplement and a week later add a separate vitamin B Complex
Then once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.
If Vegetarian or vegan likely to need ongoing separate B12 few times a week
Igennus B complex popular option too. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12
