The Microlet Vaculance is a lancing device designed to obtain capillary blood from body sites other than the fingertips. You may want to try one of the single use lancets if you choose to use a lancet without a lancing device. One way lancets differ is in the gauge. The higher the gauge, the smaller the hole in your finger. The drawback to using a higher gauge lancet is that you may not get enough blood.
Many lancets fit into any lancing devices, but there are some exceptions.
Lancets may be reused to save money, however, this practice should not be used on children. The main concern of reuse is infection. Another concern is that after reuse, the point gets dull. For that reason, don't use alcohol on your lancets. Someday, the laser-lancing device will bring transition from the conventional blood glucose monitoring to noninvasive technology.
