Help interpreting results please

Hello

I had a private thyroid check done, and it came back saying the results are within the normal range. However, I have been experiencing a number of symptoms that make me think that my thyroid may be low. I would really appreciate any help you could give me.

THYROID STIMULATING HORMONE 2.05 mIU/L 0.27 - 4.20

FREE THYROXINE 14.900 pmol/L 12.00 - 22.00

FREE T3 5.35 pmol/L 3.10 - 6.80 T

HYROGLOBULIN ANTIBODY <10 IU/mL 0.00 - 115.00

THYROID PEROXIDASE ANTIBODIES 9.07 IU/mL 0.00 - 34.00

Many thanks

Did you do your test early in the morning, no later than 9am, and delaying breakfast/tea/coffee/etc until after the test?

Your results are euthyroid (normal). In a normal healthy person one would expect to see TSH up to about 2. No-one knows where our FT4/FT3 levels are good because they're never tested when we're well. Your FT4 is on the lowish side, one would expect to see that around the half way mark, but your FT3 is good and it's low FT3 that gives symptoms. Your thyroid antibodies are negative for autoimmune thyroid disease (Hashimoto's) with this result.

Is this all you had done? Looking at nutrient levels is the next step as low levels/deficiencies bring their own symptoms, some overlap with symptoms of hypothyroidism. You need

Vit D

B12

Folate

Ferritin

Hi CKC79, could you be more specific about your symptoms? Blood tests are really just a guide, and symptoms are more important.

I'd say these results are in the normal range, but look a bit sluggish. Your freeT4 (thyroxine) is quite a way below the healthy midpoint. This is the main hormone your thyroid produces, so it gives us a sense of how productive the thyroid is. FreeT3 is the active hormone your body converts the T4 into. This is a lot higher in range than the freeT4, which suggests your body is working overtime to convert as much as it can and keep the body stable.

The TSH is just on the high end of what I'd consider normal. If it was 2.5 I'd say you've almost certainly got a thyroid problem brewing.

Unfortunately this doesn't help you much, as this is a million miles away from getting a diagnosis :(

Its possible this is a temporary downgrading of thyroid function as a result of another illness, a stressful event, burnout, depression, too much exercise, this kind of thing.

I agree with Seaside Susie you should look into vitamins. Do all you can to support your thyroid, eat right, get good rest, cut down on activity, take up meditation or yoga, cut out stress. Take seriously that you might have an illness starting up and take care of yourself. Also think about repeating these tests 6 months or a year's time to see which direction you're going in.
