Hi All!
So, following on from this post:
healthunlocked.com/thyroidu...
Blood results are in.
Plasma Cortisol (140-690 nmol/L)
24/07/18 = 237
15/09/16 = 233
The general consensus on the last post that the level of 233 (from Sept 2016) was a tad low for a 9am cortisol and there was some discussion suggesting the range given might have been for the whole day rather than just a morning range. Print out from most recent test had this to say:
"Plasma cortisol levels show diurnal variation. As a guide, morning values will be in the range 140-690nmol/L and evening values in the range 70-350nmol/L"
Am a bit flummoxed by this. So by all accounts my readings would be considered normal at night time, but also normal for first thing in the morning??? Does not compute for me. Any thoughts?
Also, a query regarding Hashis which I thought had been deemed pretty unlikely by my previous results. Except, they appear (at least the TPO does as the other wasn't tested) to have increased since my last test. While still regarded as normal, this does suggest to me that something is occuring in a wax and wane kind of way, if only at a "sub clinical" level (Results in reverse order):
24th JULY 2018
Plasma TSH (0.3-5.6 mu/L)
1.46
Free T4 (12 - 22 pmol/L
) XXX
Free T3 (3.1 - 6.8 pmol/L)
XXX
TPO antibodies (0-60 IU/mL
) 33
TG Antibodies
(0-115 IU/mL) XXX
5th JULY 2018
Plasma TSH (0.3-5.6 mu/L)
4.73
Free T4 (12 - 22 pmol/L
) 11.8
Free T3 (3.1 - 6.8 pmol/L) 3.61
TPO antibodies (0-60 IU/mL
) <9
TG Antibodies (0-115 IU/mL) <10
At this stage I had taken no thyroid meds. Both tests performed fasting and first thing. So same conditions. So as my TSH has fallen my TPO has risen (or possibly vice versa). Any thoughts ??
The upshot of my meeting with the GP today was a referall to one of the Endos from the TUK list. With a view to further assessment regarding Central/Secondary Hypo. Despite what they are regarding as normal cortisol and prolactin results I pointed out that CH can impact TSH on it's own without other hormones being affected. And that if I had a pituitary dysfunction (including potentially an adenoma) then I felt that really, this is something I should know! (Despite cortisol and prolactin being normal). "absolutely" she says! I offer the name of the Endo from the list and she addressed the letter directly to him. I know that in our area though, people are waiting over a year from referall to appointment. So I've decided to start on the Levo and see what happens in the meantime.
I feel pretty strongly that CH is likely having now read up. But always interested to hear any insights you clever lot have to offer. Bloods in reverse order as follows (same ranges as before/above):
24th JULY 2018
Plasma TSH 1.46
Free T4 - not tested
Free T3 - not tested
5th JULY 2018
TSH 4.73
Free T4 11.8
Free T3 3.61
18th JUNE 2018
TSH 2.56
Free T4 13.5
Free T3 3.34
21st Feb 2018
TSH 4.43
Free T4 not tested
Free T3 not tested
These from 2014 and 2010 I now know to hint at a possible issue despite being told everything normal:
31st JULY 2014
TSH 1.21
Free T4 9.5
Free T3 not tested
23rd JUNE 2010
TSH 0.67
Free T4 9
Free T3 not tested
Having learnt alot from you all in the past few weeks, I think that 2010 result potentially shows a CH issue
going back that far. What would you all say? I'm starting to think this could be the answer to it all. The b12, iron, folate and vit d issues with absorption, fatigue, pain, fog. The lot.
Started on Levo today (50mcg). God I hope this helps! Have agreed with GP that I will organise full thyroid panel via medichecks in 8 weeks time and they will accept the results of that and dose based on a combo of symptoms and T3/T4 levels.
Fingers crossed.
