Acceptance of health treatment claims that are not adequately supported by evidence. I dislike it when people sell ineffective and even harmful alternative health products to exploit the desperation of people with chronic illness.
It's best to test using your fingertip. Not on the flat part of the fingertip, but on the side.
Warm hands will let the blood flow better so if you hands are cold, run them under warm water for a while, and once you have pricked your finger, squeeze the finger a little if there is not enough blood.
