Had a private blood test to give a better picture. I would be grateful for any comments to help me understand them.TSH. 0.20 mU/L (0.27-4.20)
Total T4 118 nmol/L (66-181)
Free T4 21.4 pmol/L (12-22)
Free T3 4.26 pmol/L. (3.1-6.8)
CRP 12.05 mg/L (<5)
Ferritin 46.3 ug/L. (13-150)
Magnesium 0.80 mmol/L. (0.66-0.99)
Cortisol (random) 265.0 nmol/L
Vit B12 278 pmol/L (145-569)
Vit D(25 OH). 76 (optimal 75-200)
Serum Folate. 5.89 nmolL (8.83-60.8)
Anti-thyroidperoxidase abs < 9 IU/ml (<34) new unit
Anti-thyroglobulin abs 10 IU/mL (<115) new unit
Hope you can make sense of them. I got this test done so I had a better picture of what is going on. Its going to be a while before the appointment comes through. Thank you all, have a lovely weekend
Looking at your previous post am I right in thinking you do not have a diagnosis of any thyroid condition and are not on any thyroid meds?
TSH. 0.20 mU/L (0.27-4.20)
Total T4 118 nmol/L (66-181)
Free T4 21.4 pmol/L (12-22)
Free T3 4.26 pmol/L. (3.1-6.8)
Low TSH and high in range FT4 although FT3 is only 31.35% through range. Not hypERthyroid and obviously not hypOthyroid.
Anti-thyroidperoxidase abs < 9 IU/ml (<34) new unit
Anti-thyroglobulin abs 10 IU/mL (<115) new unit
Antibodies nice and low so these results show no sign of autoimmune thyroid disease. However, antibodies fluctuate and testing another time may show a different result. Also, it's possible to have Hashimoto's without raised antibodies.
CRP 12.05 mg/L (<5)
Raised CRP tells us there is inflammation somewhere. It is a non-specific inflammation marker so can't tell us what's causing the inflammation. Did you have a cold, or viral or bacterial infection at the time of the test? Do you have any kind of inflammatory condition?
Ferritin 46.3 ug/L. (13-150)
Low but as ferritin is raised when inflammation is present your normal ferritin level may well be even lower than this. It would be worth doing a full iron panel which includes serum iron, transferrin saturation percentage, total iron binding capacity plus ferritin. This would show if you have iron deficiency.
Magnesium 0.80 mmol/L. (0.66-0.99)
Testing magnesium is unreliable. About 99% of magnesium is stored in bone, muscles and soft tissues, leaving about 1% in the blood. So testing what's in the blood isn't giving an accurate picture of our magnesium status.
A red cell magnesium test is the better indicator of magnesium status, not the standard serum magnesium test. The red cell test is expensive and requires phlebotomy which is why it's not included in these bundles.
Cortisol (random) 265.0 nmol/L
You haven't given the ranges nor the time of the test.
Vit B12 278 pmol/L (145-569) = 377ng/L
This is low. According to an extract from the book, "Could it be B12?" by Sally M. Pacholok:
"We believe that the 'normal' serum B12 threshold needs to be raised from 200 pg/ml to at least 450 pg/ml because deficiencies begin to appear in the cerebrospinal fluid below 550".
"For brain and nervous system health and prevention of disease in older adults, serum B12 levels should be maintained near or above 1000 pg/ml."
Do you have any signs of B12 deficiency – check here:
If you do then list them to discuss with your GP and ask for testing for B12 deficiency and Pernicious Anaemia. Do not take any B12 supplements or folic acid/folate/B Complex supplements before further testing of B12 as this will mask signs of B12 deficiency and skew results and if you have B12 deficiency and it is not detected and treated then this could affect your nervous system. B12 deficiency should be treated before starting folic acid because folic acid can sometimes improve your symptoms so much that is masks B12 deficiency.
If you do not then consider supplementing with B12 sublingual methylcobalamin 1000mcg along with a good quality bioavailable B Complex.

Your current level of 76nmol/L = 30.4ng/ml
Vit D Council's website: web.archive.org/web/2019070... Vit D Council, the Vit D Society and Grassroots Health all recommend a level of 100-150nmol/L (40-60ng/ml), with a recent blog post on Grassroots Health mentioning a study which recommends over 125nmol/L (50ng/ml).
A lot of information there but I will look into it. The test was done about 09.10am at home and I am and was well. Thyroids been repeated since 2020 for fluctuating levels, mostly below range TSH. Dr told me last time over the phone that she thought subclinical hyperthyroid. No official diagnosis or treatment but referred to consultant.
CRP three results 2018 7mg, 2020 10mg and this one of 12.05. Highlighted at the lab but not addressed. I am concerned about this.
Cortisol was reported as I've written it.
Prescribed vit D3 800units about 25 years ago for deficiency, told I had to take them for life. I have checked and have quite a lot of symptoms. Another one that stood out from my gp notes is that one test came back with a report of large red cell and gave the % increase. The lab highlights the result but its not addressed.
so as you did your test at 9.10 then the 6-10am range is appropriate. You are within range but I don't know what the optimal level should be.
Prescribed vit D3 800units about 25 years ago for deficiency, told I had to take them for life.
Vit D deficiency would have loading doses prescribed followed by a maintenance dose of 800iu. However, that amount is not always enough. I had severe Vit D deficiency with my original level being 15nmol/L and after I increased to the recommended level I've found that I need a maintenance dose of 5,000iu daily all year round.
Another one that stood out from my gp notes is that one test came back with a report of large red cell and gave the % increase. The lab highlights the result but its not addressed.
In that case it's worth looking at a full blood count and iron panel together.
You got it, blue horizon. Those numbers are there just didn't understand as I'm new to all this. I have had the same vit d dose for as long as I can remember. Thank you for your help.
Once the recommended level has been reached then a maintenance dose will be needed to keep it there, which may be 2000iu daily, maybe more or less, maybe less in summer than winter, it's trial and error so it's recommended to retest once or twice a year to keep within the recommended range.
As you are taking D3 are you also taking D3's important cofactors - Vit K2-MK7 and magnesium?
D3 aids absorption of calcium from food and Vit K2-MK7 directs the calcium to bones and teeth where it is needed and away from arteries and soft tissues where it can be deposited and cause problems such as hardening of the arteries, kidney stones, etc. 90-100mcg K2-MK7 is enough for up to 10,000iu D3.
Magnesium helps the body convert D3 into it's usable form.
There are many types of magnesium so we have to check to see which one is most suitable for our own needs:
Magnesium should be taken 4 hours away from thyroid meds and as it tends to be calming it's best taken in the evening. Vit D should also be taken 4 hours away from thyroid meds. Vit K2-MK7 should be taken 2 hours away from thyroid meds. Don't take D3 and K2 at the same time unless both are oil based supplements, they both are fat soluble vitamins which require their own fat to be absorbed otherwise they will compete for the fat.
