I've just ordered my fingerprick tft just in time to read the post about how sore your fingers get, and when I did a site search (to reassure myself lol) I found a post where someone recommended taking the blood from the earlobe.
Now Idk if you've ever had your earlobe snipped during a haircut, but it does bleed like b*****y, and there are fewer nerve endings there. It seemed a good idea, but of course the testing company don't recommend it. Why? Because the lab recommends the fingertip.
I googled it a bit and opinion seems divided between those who think it makes no difference if you do it that way every time and those who think it makes no difference. I understand that blood glucose can be a bit different because it is used in your tissues or some such thing, but does that apply to tft? (Anyway, apparently the earlobe is sometimes used to take blood for glucose testing anyway in cases where it's not practical to use the finger, so is that incompetence or practicality?)
If I had a spare £70 I'd do a comparison, but...
Does this fall under the category or 'We do things this way because this is the way we do them' or is there an actual compelling reason? Anyone know? TIA.
