McKessonSafety Lancets, Sterile, Push-Button, 17 Gauge Blade, 2 mm, 100 Count, 1 Pack

Blue lancets are thin and dainty. Light green are larger, but to get a sample large enough for an INR test you Need Yellow. These are great. Each is a one use, spring loaded. If you need a sample for A1C, these are Not for you.

This works great for me!! I have a dog that was recently diagnosed with diabetes, and those lancets that are very tiny (for humans, of course) were proving very annoying because they were too small to csuse a droplet of blood. I would have to stick multiple times, which made me feel like I was being mean. Now, with just one easy stick, I can get a drop of blood, test it and be done! No more anxiety trying to check my pup's blood sugar! Thank you, McKesson!

all you got to do was twist off the tip, hold steady and push down. More than enough blood comes out. quick & painless, maybe a pinch if that. good product.

Only complaint is that the puncture location is very random.

My 70 year old dad has tough skin from working with his hands for years. He would prick his finger and no blood would come out. So, he'd try pressing harder. We started to joke that he was a vampire. Thankfully we don't have to over prick him or joke anymore because these work great.

Its great lancet, the uses is very simple and give the results perfect every time, I exam my blood on microscopy every week to follow up, how healthy my blood is, the lancet give the exact blood sample, without the trauma on the blood that could affect results on live blood viewing.

Good quality lancets but the paper box they came in was not sturdy at all. The box was not even sealed so half of the sterile lancets ended up in the plastic shipping bag.

Click! Big drop of blood and barely any pain. Great for acupuncturists wanting to bleed jing well points!
