This sample is then used in a machine in order to analyse for any irregularities in sugar as well as other abnormalities.
Lancets vary in brand as well as gauge and size.Lancets have different depths and and settings.
Gauges range from 22-24-26-28-33.
Lancets are single use and sterile – this reduces the chance of an infection.
The best place to draw a blood sample is the side of the finger. Warming up your hands will also assist in getting a proper specimen.
