I was at the pharmacy today picking up a prescription, and I noticed the blood glucose testers for sale behind the counter. The most expensive one was $74.95. I had to wonder why they are SO much cheaper than a protime machine...of course, they aren't for sale in the pharmacy, which may be the reason, but last time I tried to get one it was $2,500, and even going through my brother the dr., his price to get one was $700. That's such a huge difference for something that seems to me to be similar, and I was just wondering....why is that? I know the number of protime home testers is much lower than that of diabetic home testers, so less machines made; maybe I am answering my own question! Still had to ask.
