Lancets are small needles that are used to prick the skin to obtain a blood sample. Many lancets can be used with a lancing device that helps to make it more effective and less painful, however, it can be used without one by just sticking the skin with the lancet.
Although the lancet can be used alone to get a sample, it is much easier to use the lancing device. The device provides a quick “punch” of the needle into the skin to make an effective and less painful stick. Smart Health, which is a popular brand of diabetic supplies, has a device that is easy to use. Each brand’s device will be a little different, but the general idea is the same. The following steps demonstrate how to use the Smart Health device.
Step 1. Always wash your hands before checking your blood sugar. If there is any bacteria on your hands and gets into your bloodstream, it can cause a major infection! First, take the cap off of the device and insert a new lancet with the safety cap still on. (If it is removed first, you can poke yourself!) When you insert the lancet, do not twist it around. It should easily fit. See the image below for a better description.
Step 2. Take the safety guard off of the lancet to expose the needle. This can easily be done by simply twisting the small circle and pulling it off. Then put the cap to the lancing device back on carefully without poking yourself.
Step 3. Many devices have different depths that you can choose from. This allows you to have a less painful finger stick. (This will be discussed later!) Based on your needs, pick the depth that is best by twisting the cap to the appropriate number. On the Smart Health Lancet device, there are 9 different settings to choose from, with 1 being the shallowest and 9 being the deepest.
