A blood sample taken via plastic lancet contained 42 plastic particles, while a sample taken via a metal lancet contained 1 plastic particle.

“The plastic uh things are very easy. You just hit the fingertip and then you're done. Uh this you have a metal like it's a metal sword or metal spear. It's hard to stick that in your finger if someone else can do it for you. But just a heads up, we've tested a metal lancet versus a plastic and the plastic lancet uh does cause a lot of to uh plastic exposure in the test. So you get an inaccurate reading. So you need to use the metal lancet in order to get the accurate results.”
