Hi, I am a 42 year old women, with three children. I previously posted on a bit about my medical history : (20 years ago I was diagnosed with M.E now been told I have CFS and Fibromyalgia, recently been very tierd,sore and stiff with bad headaches and rashes and also been diagnosed with raynauds disease & roscea) Kindly I was replied to on this forum and advised to find out my blood test results and post them on. I am picking up a full copy on Tuesdaybut was given the following which I do not have units or ranges for but was advised that myTSH was normal and my free t4 normal, but had antibodies present (anti thyroid peroxidase). Apparently no free t3 results. Results as follows:
TSH 4.0 (at present i have no ranges will try to acquire from doc.)
FREE TS4 12 & no FREE TS3 was taken or least recorded.
ANTI-THYROID PEROXIDASE - 124.1 (Dont really know what that indicates or if this is high?) GP said out of normal range!
My GP stated that the antibodies meant that I had to have an annual thyroid check up but other than that had no bearing on my health or any of my current symptoms. I have been feeling really awfull recently for last 2 months and am now unable to continute with my university course so really just desperatly seeking some answers for myself and my family who have been up and down with me for last 20 years. My husband and parents have been a contsant support and really a lot of the time I would struggle without their help. Can anyone advise regarding my results. Thankyou.
Mona,
Taking a guess at the ranges (and in the UK though they vary, they tend to be fairly similar), I'd suggest the following story.
You are fairly early in having Hashimoto's thyroiditis. The antibody test allows for a very low number being normal - the threshold below which the test is negative. Above that number, as you are, means that something is attacking your thyroid allowing thyroid peroxidase to spill into the blood stream. These antibodies are there to mop up that spilled thyroid peroxidase. They are not what are attacking your thyroid.
In the earlier stages of Hashimoto's it is quite common for the free T4 level to drop (and you are towards the bottom end of the range for that). But, as if to compensate for that drop, the free T3 level can rise. The overall effect is that your TSH remains only modestly raised. That is one of the reasons that excessive reliance on TSH testing is inappropriate.
At some future point you can expect your ability to maintain that relatively elevated free T3 level to diminish. And then your TSH might rise markedly. Whether this will be slow (months, years) or fast (days, weeks) I really don't know.
The thing that is often forgotten or ignored is that if you have one autoimmune condition you seem to be at higher risk of having others. All the other diagnoses you have had, or suspect, could at least have some autoimmune element to them.
On a personal note, though I do not have antibodies (hence do not have autoimmune thyroid disease), I was diagnosed with a TSH only a bit higher than yours (just over 5), and free T4 of 12. And I have distinctly improved since starting thyroxine.
