I posted a week ago about my friend doubting the private finger prick tests reliability and how it concerned me.
She had an NHS test a few weeks ago just before 9am, her TSH was 3.6 (0.3-5.5). She did a private test Thursday with Medicheck and she has had her results today TSH 4.65 (02.-4.2) and FT4 16.04 (12-22).
The reason she doubted it was her TSH was 5.8 back in April with Medicheck, I told her things can improve and it doesn't always lead to full on hypothyroidism. She was very stressed earlier this year.
The thing is there is a whole point between the recent NHS and recent Medicheck results. I have told her that results differ depending on the range but my friend is sure that isn't the case, a result is a result. Is this right? I am interested to know
TSH fluctuates, even through the day, let alone over weeks. It's a snapshot. Unless you draw the blood at the same time on the same day and send them to the different labs you're not doing a comparison that has any meaning.
I think a TSH result is a result. The ranges are based on a different approach to treatment levels.

Thank you.
They are a few weeks apart and I said they can fluctuate. They are the same time of day both times but it can change slightly. It's only if like mine which rocketed from 7.5 to 9.28 in a few weeks it shows there may be a need for treatment. Her TSH is still above normal but GP won't acknowledge that.
