Here’s a snippet below of what you can further read at this link -
“I wrote up a blog a few weeks - about taking a rest from testing my fingers (My Porky Pigs Fingers are tired). Well, Doris a frequent poster here posted a reply and she pointed out - which I didn’t know about - and I quote - “Please just remember that using any place other than your fingers is less than accurate due to proximity to the heart”. Lordy, lordy - this is news to me about the heart bit effecting my blood sugar readings when I test - I feel like Jethro from The Beverly Hillbillies . I mean here in Canada not having the use of the Joslin Institute that some of you are fortunate enough to have makes me feel quite inadequate to say the least. Sigh.”
