What Is A Lancet?

A lancet is a needle encapsulated in plastic and is used for puncturing skin to get a blood sample. Lancets are also known by many other names such as needle, pricker, and finger sticks, but they all refer to the same thing. Lancets are commonly used by people diagnosed with diabetes while measuring blood sugar levels. There are many different types of lancets and they also vary by gauge (needle thickness) and penetration depth (needle length). Gauge is a bit tricky, as the bigger the number the thinner the needle and the opposite is true, the smaller the number the thicker the needle. Thicker needles (small gauge) make bigger holes which allows for better blood draw, but they're also more painful than thinner needles (large gauge). So if you are sensitive to pain you might want to start with a larger gauge lancet. Keep in mind that the smaller the puncture the longer it will take to get enough blood sample for the glucose test. If you do not squeeze out enough blood you will not only have to redo the lancing procedure but also ruin the lancet and the test strip which in some cases could be a very costly mistake. So make sure to consult your physician to find out exactly how much blood sample your glucometer requires to produce accurate results, this will allow you to make an educated decision and purchase correct lancets the first time.

What Does Lancet Gauge Mean?

Lancet gauge number means needle thickness. The bigger the number the thinner the needle and the opposite is true, the smaller the number the thicker the needle. Please refer to the following chart for clarification of the most common lancet needle thicknesses:

  • 33 Gauge, 33G is 0.20mm
  • 32 Gauge, 32G is 0.23mm
  • 31 Gauge, 30G is 0.30mm
  • 28 Gauge, 28G is 0.36mm
  • 25 Gauge, 25G is 0.51mm
  • 23 Gauge, 23G is 0.63mm
  • 21 Gauge, 21G is 0.82mm
  • 18 Gauge, 18G is 1.27mm

Can Lancets Be Used Without A Lancing Device?

Most lancets do require to be used with a lancing device, although, there are variations of lancets such as Pressure Activated lancets which do not require a lancing device, they are also known as single-use disposable lancing devices. There are many different brands who manufacture lancing needles and devices. Most brands manufacture a proprietary combination of a lancing device and lancets, and lancets from other brands are not interchangeable. It is important to note that most lancets are not universal and can not be inserted into random lancing devices. So if you are shopping for lancets please make your selection carefully and make sure that lancets are compatible.

The Benefits Of Using A Conventional Lancing Device vs Single-Use Disposable Lancing Devices?

An important function of a lancing device is the ability to change the penetration depth (needle length) of its lancet while most single-use disposable lancing devices have a set penetration depth, although there are exceptions such as Accu-Chek Safe-T-Pro Plus, which feature multiple depth levels. Also, a conventional lancing device can use various gauge lancets where a single-use disposable lancing device only has a set gauge.

Can Lancets Be Reused?

Lancets are for single use only and should be disposed of immediately after use. Repeated use of the same lancet can lead to serious infections.
