Medichecks: "Contradictory Results"

[leylandi]

Is this a rogue result for T4 or could there be a rational explanation?

Thyroid Hormones

:

TSH 0.04 mIU/L (Range: 0.27 - 4.2)

Free T3 4.34 pmol/L (Range: 3.1 - 6.8)

Free Thyroxine 11.600 pmol/L (Range: 12 - 22)

Inflammation

: CRP HS X 9.93 mg/L (Range: < 5)

Iron Status

: Ferritin X 29.6 ug/L (Range: 30 - 400)

Vitamins

Folate - Serum 8.36 ug/L (Range: > 3.89)

Vitamin B12 - Active 150.000 pmol/L (Range: > 37.5)

Autoimmunity

Thyroglobulin Antibodies X 591.000 kIU/L (Range: < 115)

Thyroid Peroxidase Antibodies X 48.4 kIU/L (Range: < 34)

I do not take Biotin nor keep cattle, sheep or mice which Medichecks suggested might have affected the results (and took no supplements for a week prior to the test).

Your thyroid results are similar to mine! Suppressed TSH and T3 normal, with low T4. You seem to need slight more T4. Advice on here is that T4 is better in the middle to top of the range.

Your Ferritin is low. Do you take iron supplements ?

Do you also take B12? Readings are high for this. If you do, stop?

What medication do you take?

I'd say you have scope to increase T4, if you feel a need to. If you're taking T3 or NDT, that explains the result.

It's bugging me that medichecks don't have an upper limit on B12 these days. How else do you know when it's good enough!

How much Levothyroxine are you currently taking?

Previous post two years ago says 50mcg, which is only a starter dose

Both FT4 and FT3 are low, suggests you need dose increase in Levothyroxine

Your high antibodies confirm you have autoimmune thyroid disease also called Hashimoto's.

As you have Hashimoto's Are you on strictly gluten free diet?

Low vitamin levels often lower TSH

Ferritin is very low. Ask GP for full iron panel testing for Anaemia

Eating liver or liver pate once a week, plus other iron rich foods like black pudding, prawns, spinach, pumpkin seeds and dark chocolate, plus daily vitamin C can help improve iron absorption

Do you supplement B12?

folate on the low side. Supplementing a good quality daily vitamin B complex, one with folate in not folic acid may be beneficial.

B vitamins best taken in the morning after breakfast

Igennus Super B complex are nice small tablets. Often only need one tablet per day, not two. Certainly only start with one tablet per day after breakfast. Retesting levels in 6-8 weeks

Or Thorne Basic B or jarrow B-right are other options that contain folate, but both are large capsules

If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before any blood tests, as biotin can falsely affect test results

You need Vitamin D tested too

We need to know what thyroid hormone you are taking. You have high antibody levels which suggests autoimmune thyroid disease. This can cause erratic release of hormone especially T3, this would explain your results. If this is the case it's quite possible you've had periods of high hormone levels and this can suppress TSH for quite some time, many months. Sometimes the TSH levels do not normalise.

[SlowDragon Administrator]

Your results are typical of someone on Levothyroxine plus T3 or NDT in that TSH is suppressed despite low FT4

Depending on your symptoms.......they suggest perhaps you are in need of dose increase
