Hi. I posted my private blood test results yesterday and question about T3 and NDT. I had so many comments and I thank to all of you who took time to respond.
I had a phone consultation with a consult endocrinologist this afternoon. Well, that was interesting. Some things were predictable like basing any decisions regarding dosing of meds on TSH alone (when questioned, she simply replied that that is what their medical body requires and that it is a hormone that indicates the level of hormones produced, didn't want to go into discussion about T4 and T3 of course).
So basically, my blood test results from last Wednesday in my GP surgery were:
TSH 0.76 (0.35-4.78),
FT4 16.3 (10-20) 63% through range
Yesterday I posted my Thriva results from this Monday:
TSH 2.19 (0.27-4.20),
FT4 14.4 (12-22) only 24% through range
I took the blood tests at similar time 9 am, fasted state, after last T4 dose 24 hours earlier. How come there is such a discrepancy? Is it because one was pin prick and one venous blood draw? I asked her that and she said, because they may use different assay (procedure for measuring) - but the ranges are very similar. My GP blood test in March was TSH 0.94 but I took Levo that morning so no good.
Of course according to her results, my TSH is lower than NHS target of 2 (and even lower than our target of 1) and she didn't want to increase by 25 mcg due to worry of me being over medicated - I guess her hands are tight because of blood test result? She actually said, she was more inclined to lower to 75 mcg as TSH needs to come higher. Some symptoms I have of tiredness, mood swings, nervousness can be both hyper and hypo. I do sometimes feel faster heart beat.
Because of my quite bad symptoms of joint and muscle aches and sluggishness, the endocrinologist suggested it may be Levo brand related (her Mum changed meds and felt much better). She advised me to go to pharmacy and change the brand and see what effect it will have and whether my symptoms will improve. I will get another appointment in 3 months and a blood test a week before that.
As for meds, I think I used to be on Mercury Pharma 100 mcg and that changed to North Star but I am not sure when as I never paid attention to these things before so cannot say if the symptoms worsening was around that time. My local pharmacy, where I went straight after the phone call, could't give me my meds history and when I asked them to order Mercury Pharma, they said it was very difficult to order different brands (they get what they are given - probably the most cost/profit effective option) so for them administrative, logistical and financial nightmare. But she agreed to try to order some for tomorrow but couldn't guarantee that they will receive it. My next option is to take the prescription and go around local pharmacies to find out what brands they stock (I already checked with one that has Aristo and Teva (no way I am touching this one as I am learning fast on here).
So, I am a bit confused as to what I need to do and what blood tests to believe really - I know that symptoms are always the best indication but as I said they can be quite similar. But officially, no increase of meds for me at the moment. My journey may be longer than I thought.
By the way I asked her about testing FT3 and why I wanted it but luckily that was at the end of the consult and she quickly but at least politely ended my already long consultation. I wonder why? lol
