Glucometer to use on multiple patients - page 3

Hi All, I need to get a glucometer to use in a research study on multiple participants. I have 2 questions: 1. What glucometer do you like? 2. what single use disposable lancets do you like? Your help is very much... Read More

If it's something you'll have to graph or find a stdev on, you may want to take a few reading from a single poke with a longer lancet. The hopital I'm at school at uses single use lancets with a purple cap and an adjustable lancet; I'm sorry I don't know the brand. Good luck!

For more dependable information I would do hA1c tests on subjects. That would give you a much more accurate result.

But.... if you really want to be sure you've excluded diabetics, and you don't really exclude them, your pilot results may be unreliable, and then what? Want to defend that to your committee? ::shudder::
Do the A1c.
- 0No committee for me. This is full professor driven and they feel is it close enough for the purpose of this pilot. With pilot studies you have a lot more lattitude. Then when the evaluation happens and if is decided to go ahead that is when things will get very stringent. No way are they going to cover the cost of A1c's along with everything else for a 20 subject pilot. Diabetes in and of itself is not an issue. Just they want "generally healthy".

Like GrnTea said, with the standard kind that uses a different disposable test strip for each use, I don't see where there's a risk for cross contamination.No, you and I are in long term care, where this is standard. I don't think Crunch is.....
- 0Feb 8, '13 by Meriwhen Senior ModeratorQuote from BrandonLPNThat's the type we use (Accu-chek with the single-use test strip, used with the single-use disposable lancet), yet they still make us scrub the machine down between each stick. I'm inclined to agree with you though--unless the patient's blood gets loose on the equipment, there should be minimal risk of cross-contamination.I think we must use a different kind of glucometer.
