Your new results show that your FT4 is under range suggesting undermedication yet your TSH is still low in range.
When did you take your last dose of Levo before the test?
Do you take Biotin or a B Complex or any supplement containing biotin? If so did you leave it off for 3-7 days before the test?
Also my plasma creative protein (0-5) has gone from 2 to 22
Erythrocyte sedimentation rate (0-15) 28
These are both inflammation markers and being over range show that you have inflammation.
These results, coupled with your large drop in FT4, could suggest Hashimoto's. I know that a previous test showed no elevated antibodies, but because antibodies fluctuate they could be raised another time, plus it's possible to have Hashi's without raised antibodies.
Could there be any other cause for inflammation? Recent infection? Rheumatoid arthritis, etc?
Serum gamma GT level (0-45) 69
Raised GGT level can be a sign that your liver isn't working properly. Has your GP discussed this result with you?
My Levo was taken the night before and I gave blood at 10am the next morning.
That will have given a false high FT4 result.
We should leave a gap of 24 hours between last dose of Levo and blood test to get a measure of the normal amount of circulating hormone. When we take Levo at night we adjust timing for a couple of days before the test to provide for the correct time gap.
The only other thing is I did have COVID about 6 weeks ago. Could that affect me now?
So little is known about Covid and how it can affect us. I had high hormone levels for a few months after my booster jab and I've had to slightly adjust my dose, so it's very possible that having Covid so recently may have skewed results. Plus you may still be having effects of Covid, my daughter had the Omicron version and suffered no more than having a bad cold but it's left her with tinnitus. It's not possible to know how an individual will be affected. Maybe that's the reason for your raised CRP and ESR, but I don't know about the raised GGT I really think that is something for your GP to look into.
Hi SlowDragon,My vitamins are always low. I do supplement but not 100% it’s difficult as you probably know, getting all supplements in the correct times.
I couldn’t tell you all the brands but they were recommended on the Facebook page.
It is likely COVID has affected your results, hopefully short term.
Having the blood taken about 12 hours after your last levothyroxine dose is ideal, it will give a result that reflects your average fT4 level, similar for TSH and fT3. If you were to leave 24 hours between your last dose and taking the blood you would get a false fT4 figure but only about 5 percent lower.
If you have the option I would take a little liothyronine for a few weeks until my body recovers. You didn't measure fT3 but it is possible you have low T3 syndrome which is how the body responds to an infection. Hopefully you will recover within a few months.
