Help interpreting Test Results Please.

[HPMandy23]

Could someone please kindly help me understand what these results mean?

This is the 3rd time I’m over a year my CRP is high. I have been taking supplements so I understand why my Vit D and B are also high.

I’m concerned about the Reverse T3 number. What could this possibly mean?

The over-range rT3 - it's not that high - doesn't have anything to do with your thyroid.

It's really not worth testing rT3 because the result will tell you if it's high, but won't tell you why it's high. And there are many, many causes of high rT3, only one of which has anything to do with thyroid. And, your FT4 isn't high enough to be the cause of high rT3, so it must be something else:

· Chronic fatigue

· Acute illness and injury

· Chronic disease

· Increased cortisol (stress)

· Low cortisol (adrenal fatigue)

· Low iron

· Lyme disease

· Chronic inflammation

- Low iron

amongst many other things. But, the high rT3 won't hurt you. It just tells you there's a problem somewhere in the system. Down to you to find out where.

It's not worth testing magnesium, either. Your result can be high but that doesn't mean you're not deficient due to the way the body handles magnesium. And, if you're taking vit D, you should also be taking magnesium because the two work together.

As to the thyroid results, we first need to know if you are on thyroid hormone replacement. If so, you are under-medicated.

Thank you. I am not on any medication at the moment

[greygoose in reply to HPMandy23]

At the moment? So does that mean that you have been on it?

Your TSH is a bit high and indicates that your thyroid is struggling to maintain euthyroid levels of FT4/3. But, you're not quite hypo yet.

Antibodies are negative in that test. Have they ever been tested before?

[HPMandy23 in reply to greygoose]

I have never been on any kind of Thyroid medication. Gp has always said all fine and normal.

Last Antibodies test results from a year Ago were.

Thyroglobulin : 15.87

Thyroid peroxidase: 14.02

[greygoose in reply to HPMandy23]

Well, the GP will continue saying that until your TSH goes over 10, I'm afraid. They tend to ignore the reference ranges and set some arbitary point way above. But, keep testing occasionally, to see how things develop. You could go hypo, with time. Do you have hypo symptômes? Have you ever had an ultrasound of your thyroid?

This is the 3rd time I’m over a year my CRP is high.

Did you have doctor's comments? If so this would have given an explanation of the CRP test and what it indicates.

As it is an inflammatin marker, when CRP is raised one might expect to see Ferritin raised too if inflammation is present. Is your ferritin higher than normal too?

Some of us tend to have a higher than usual CRP level due to other conditions. I have COPD and my CRP is always in the upper half of the range, and sometimes over if I am experiencing an exacerbation/lung infection.

The "hs" CRP test is more sensitive and can measure lower levels of inflammation than the standard CRP test. The inflammation from atherosclerosis (hardening of the arteries [which tends to come as we age]) is a low level of long-term inflammation that produces only small amounts of CRP so this could show up in the hs-CRP test. I have atherosclerosis to a degree which showed up in a brain scan and was told it was normal for someone of my age. This could also contribute to why my CRP level tends to be fairly high. However, my ferritin is never raised, that's something I struggle to keep at a reasonable level, so it does get a bit complicated.

If you are concerned, you should discuss this with your GP.

High reverse T3 can have many reasons. Liver problems can cause it as T4 is converted to T3 in the liver. Viral infections can cause high RT3. Mine was very high when I had glandular fever.

Vitamin D is very high

Presumably you have been supplementing?

Suggest you reduce dose/ stop for a while
