Your most comfortable setting will depend on a few things:

• Whether you're using a fingertip or an alternative site. Talk with your healthcare professional before deciding if alternative site testing is right for you.
• Your skin type. Softer, thinner skin requires a shallower setting than thicker skin.
• The required blood sample. The more blood you require, the higher the setting you'll need.

Start with a low setting when using the lancing device for the first time. Dial to a higher setting until the blood volume is right. For alternative sites, try 3 for palm testing or 5.5 for forearm or upper arm testing. (These are suggested settings, yours may differ.)
