The amount of blood required to fill the fingerstrip may be different from one glucose machine to another. Glucose monitoring machines normally require a very small amount of blood to determine glucose levels. You can figure out the amount of blood required once you use the strip. The fingerstick strip will suck up only the amount necessary to determine results. The amount of blood required can stem from a small prick of the finger. If the strip is still not filled, you can squiz the finger for a little more blood to fill the slot for blood on the finger strip.
