I won't mention the product specifically by name, but I'm having a whale of a time getting enough blood out of my finger after using the enclosed "lancet" when trying to utilize a well-known home cholesterol test kit. Even after warming up my arm, hand, and finger, as well as "massaging" the fingertip, not enough is coming out.

Thoughts? I'm not nervous and not cold. I've followed the instructions completely. I just cannot get enough blood to fill the little hole. Plus the time limit for doing so is very strict. Thanks.
