The folks that make the lances will tell you to replace the needle every time you use it. Of course they do, they are in the business of selling you lancing needles. The truth is, you can use it many more times. How long? It depends how tough your hide is and how often you test. I know one
girl who uses a needle for a year. That’s extreme. I say use it until it hurts, then you know it is getting dull.

For most folks anywhere between aweek and a month is the lifespan for a lance. Odds are you’ll accidentally stab yourself when you change the lancing needle; if you do, go ahead and check your blood sugar. No point in wasting a perfectly good drop of blood.
