High Cortisol and unusually higher TSH blood test results.

I have not felt well for a couple of weeks and the duty GP reduced my Levothyroxine dose after an incorrectly taken blood test at hospital (wrong time and not long enough after taking levothyroxine medication). My TSH from that poorly conducted test being 0.23 miu/L, which was not as low as I was expecting.

I decided to take a thyroid blood test with Blue Horizon, even though it had not been 8 weeks of same levothyroxine dose because I have been feeling so ill.

I have now received blood test results from Blue horizon. They are a bit concerning in terms of the Cortisol result. I totally appreciate my fT3 is on low side with poor conversion. My biggets concern is the Cortisol result as I have been feeling very jittery for some time now.

TSH 1.63 miu/L (0.27 - 4.2)

Free T4 18.2 pmol/L (12- 22)

Free T3 3.8 pmol/L (3.1- 6.8)

Cortisol 593 onmol/L (73.8-507.0) This is my second high Cortisol result in a few months.

Not an expert but wonder if T3 being low you body is living on adrenalin?TSH is only going to go up and T3 and T4 down so make GP retest and put dose back -trial has not worked.

Sorry your struggling.

low Ft3 means you’re running of adrenal hormones instead of thyroid

Retest vitamin levels at next test

Have you been taking separate methyl folate to improve you folate levels

If Ft3 remains low look at getting T3 prescribed alongside Levo

Here’s link for how to request Thyroid U.K.list of private Doctors emailed to you, but within the email a link to download list of recommended thyroid specialist endocrinologists who will prescribe T3

Ideally choose an endocrinologist to see privately initially and who also does NHS consultations so that might eventually transfer to getting T3 on NHS

Many thanks for the information, particularly about the blood tests I need. I have been taking methyl folate but my recent folate result is 8ug/L (3-20.5), serum iron is 10 umol/L (9-30), transferrin saturation index 19% (15-50) but my serum ferritin 357ug/L (30-250) following an iron infusion 11 months ago. I have severe absorption problems with tablets but obviously need to persevere given how unwell I feel currently.

I am looking to order the monitor my health test kit you recommend, but am wondering if it would be useful/valid just after a number of changes to my levothyroxine medication, which was 125 mcg daily but reduced to 100mcg by a duty GP a week ago. Many thanks for your advice SlowDragon.
