Blood Test Results

Hi all

I have an underactive thyroid and following the advice of people on the forum I got my Vitamin levels checked. My Vitamin D and Folate came back defficient, and GP has just phoned today to say my iron is defficient. However on the results online, I have noticed that there is another result which looks high, but the GP hadn't mentioned this:

Serum C reactive protein level 11 mg/L [0.0 - 5.0]

How concerning is that level? If the GP hasn't mentioned it, I'm not sure whether it's worth bringing up or anything to worry about

This basically shows inflammation. It could be if you have under treated hypothyroidism, coupled with low vitamins your body is a bit stressed. I would tell your GP that youd like to know more about this resuly though so he/she can explain.

Hi waveylines , thank you so much for your reply! I actually noticed that back in 2017, I had a C Reactive Protein level of 20 mg/L and after an increase in Levo it went down to 6 mg/L

I did have TSH tested a few weeks back and the level was 1.9, could that have caused the CRP to rise back up to 11 mg/L? It's a lower TSH than when I had a level of 20 mg/L

The other thing I have read is that Coeliac inflammation could be another cause of high CRP. I'm waiting for a test to come back on that, but did find out my grandma had it herself

Yes it could well be contributing......has your thyroid meds been raised since test result? TSH of 1.9 is too high......should really be 1 or under. What was your ft4 and ft3 ......please include the ranges. My CRP was also raised. I went on a gluten free diet last December. i feel much much better.....my digestive issues have settled except am still a bit sensitive to coffee. My GP thinks I probably have Gluten Ataxia. Not heard anthing from the clinic she referred me to but guessing I wont for months yet due to pandemic. Not keen to go back on a gluten diet as the smallest amount upsets my tummy & makes the tremors worse.

Hi waveylines , so I sent a message to my GP practice today regarding the raised CRP and the lady that replied explained CRP to me. She then said that she noticed from my record that my blood test was taken a couple of days after my Covid vaccine. She said that the vaccine will cause a raised CRP on most people as it triggers a response in the body to protect from a virus

You almost certainly need 25mcg dose increase in levothyroxine

Just testing TSH is completely inadequate

thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

cheapest option for just TSH, FT4 and FT3

£29 (via NHS private service ) and 10% off down to £26.10 if go on thyroid uk for code

Presumably you have autoimmune thyroid disease also called Hashimoto’s diagnosed by high thyroid antibodies

Hashimoto's frequently affects the gut and leads to low stomach acid and then low vitamin levels

Low vitamin levels affect Thyroid hormone working

Poor gut function with Hashimoto’s can lead leaky gut (literally holes in gut wall) this can cause food intolerances. Most common by far is gluten. Dairy is second most common.

According to Izabella Wentz the Thyroid Pharmacist approx 5% with Hashimoto's are coeliac, but over 80% find gluten free diet helps, sometimes significantly. Either due to direct gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link)

Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and slowly lower TPO antibodies

You need to continue eating gluten if coeliac test is positive, until you get endoscopy (max 6 week wait)

Assuming coeliac test is negative you can immediately go on strictly gluten free diet

Trying gluten free diet for 3-6 months. If no noticeable improvement then reintroduce gluten and see if symptoms get worse

Non Coeliac Gluten sensitivity (NCGS) and autoimmune disease

ncbi.nlm.nih.gov/pubmed/296...

The predominance of Hashimoto thyroiditis represents an interesting finding, since it has been indirectly confirmed by an Italian study, showing that autoimmune thyroid disease is a risk factor for the evolution towards NCGS in a group of patients with minimal duodenal inflammation. On these bases, an autoimmune stigma in NCGS is strongly supported

ncbi.nlm.nih.gov/pubmed/300...

The obtained results suggest that the gluten-free diet may bring clinical benefits to women with autoimmune thyroid disease

nuclmed.gr/wp/wp-content/up...

In summary, whereas it is not yet clear whether a gluten free diet can prevent autoimmune diseases, it is worth mentioning that HT patients with or without CD benefit from a diet low in gluten as far as the progression and the potential disease complications are concerned

restartmed.com/hashimotos-g...

Despite the fact that 5-10% of patients have Celiac disease, in my experience and in the experience of many other physicians, at least 80% + of patients with Hashimoto's who go gluten-free notice a reduction in their symptoms almost immediately.

Hi SlowDragon , have no idea yet if I have Hashi's or not. Can't afford antibody test atm as out of work, and I know it can be difficult to get GP to test them

Have you checked previous test results to see if thyroid antibodies were tested in past?

If not been tested yet.....Ask GP to test thyroid antibodies at next test

clatow23 in reply to SlowDragon

Hi SlowDragon , GP has never tested antibodies. Next thyroid test at GP isn't due until next year now - would you say to wait until then or ask them sooner?

Just replied on older post

Yes definitely...push for thyroid testing in 2-3 months .....6-8 weeks after you add all vitamin supplements and make dietary change to gluten free diet
