Blood Test

Hi Everyone would like some advice on blood test I am having done through Blue Horizon as recommended on here. I have gone for the 15 point test which hopefully will give me the best indication as to why I feel so rubbish. Is there anything I should do prior to test? I know I have to fast for 8 hours and make sure I drink plenty of fluids. Do I take my medication that day? Are there any other things anyone would recommend?

Thank you for your help it really is appreciated.

Merry Christmas to you all.

Allow a gap of 24 hours between last dose of levothyroxine (if you are prescribed or take any). It should also be a fasting test and at the earliest possible as TSH is highest then and drops throughout the day. Food or coffee can reduce the TSH.

Thank you so much, it worried now as they have given me a 4pm appointment is that too late?

If it is for a blood test for your thyroid hormones - yes it is too late.

I'd make a new appointment and get the earliest possible blood draw. It can make the difference between being diagnosed or not as the TSH is highest early a.m. and drops throughout the day.

I always make my appointment well ahead so I do have the earliest one.

Thank you for your reply, I will get it changed, yes it is for my thyroid I am currently taking 150mg of Thyrovanz NDT but not feeling great so thought I would go for a full blood test as my GP just says my levels are normal but my body aches so bad, Have headaches, cannot sleep at all and cannot lose any weight.

Keep in mind that blood tests were introduced along with levothyroxine, which is for T4 only.

Therefore if we add T3 to T4 or take NDT, the tests wont correlate and it is all about how we, the patient feels on a particular dose, i.e. slowly relieving clinical symptoms. I will give you some links which might be helpful and they were by an Adviser to ThyroidUK before he died due to an accident.

He only ever took on blood test and that was for the initital diagnosis, and thereafter it was all about the relief of our symptoms - that was the priority.
