Glucose Test - does site matter ?

I'v tested Fingers and arm.For myself it wasn't enough difference unless readings were questionally too high or low.Now thats just for me. Others may be different. I in ject Lantis and Novalog.Use fingers most of the time Loose

I was also told to wash your hands good before testing to remove any sugars from the surface.
Once statement made here has me wondering. Blood oxygen was mentioned. I often vary the time I take my morning reading, often within minutes of removing my CPAP Mask. What difference would I expect?

I've noticed the same thing. I test mostly on left hand but sometimes the right. The difference of two points or five won't make to much change with the same dose. I take Lantus and without any guidance from anyone it is now at 90 units at night, whcih most days will maintain, within a few points the average from when I wake up. I still have to adjust with Novalog 30 units at meals and adjust after 3 hours if needed. tried 200 units of Lantus, 100 ad bedtime and 100 units 12 hours later and still had to take lots of Novolog plus it made me feel like******all day. I'm going to have to find an Endocronologist. I've aske to see on, at the VA for 20 years. I have to have severe problems instead of stopping me from getting to that point. They could hopefully make lise so much better.

I've noticed differences but not more than 5 points. Wish the home test A1c device would come down in price.

I prefer to use my thumbs but I only test once a day normally. My other fingers seem more sensitive.
My numbers have been rising to an ave of 150 from 110 since I started Lipitor but cardiologist insist I stay on it because of AFib.

Take a good look at your fingertips with a magnifier sometime. Mine looks like a well used pincushion.

You can use the same finger and get varied results. Different meters guarantee varied results by different percentages, but all, I believe, are within 10%. Some ads suggest you can use the fore arm and such, but the furthermost extremity (fingers, hands) give the best results.
I test 6 time a day, left hand for odd numbered days, right, even. Use every finger on the hand and then the heel.

A1c is the real test. Finger prick is a guide, there are so many variables it's amazing the accuracy is what it is.

I thought I'd chime in...

For 15 years now the TWO sites I have used are... look at your "finger prints"; ring finger off center of the finger print toward the pinky on the ring finger. That has always provided more than sufficient blood, is NEVER sore, has no scarring. Don't get too far around to the side and stick into the joint/boney area.

Worst finger to get blood from is the index finger.

Do not stick directly into the finger print pad of your finger unless you want soreness.
