What Is a Lancing Device?

What Is a Lancing Device?

A lancing device is a small, handheld tool used to prick the skin and collect a small blood sample needed for blood glucose testing.

For the roughly 38.4 million Americans living with diabetes 1 , at-home blood sugar checks can become part of long-term care, making a quick and reliable blood sample an important part of the process. A lancing device helps make these routine checks feel more convenient, controlled, and comfortable for users.

How Does a Lancing Device Work?

A lancing device uses a tiny, sharp needle called a lancet to gently prick the skin and produce the small blood sample needed for at-home blood glucose testing. To do this, the device uses a spring-loaded mechanism to quickly push the lancet into the skin before retracting it almost immediately.


Most lancing devices also include a depth dial that lets you adjust how deeply the lancet penetrates the skin. This added control can help make blood sugar testing more comfortable while still producing enough blood for an accurate reading. Once the skin is pricked, a small drop of blood forms at the surface and is placed onto a glucose test strip for testing.

Lancing Device vs. Lancet — What’s the Difference?

A lancing device and a lancet may sound similar, but they play different roles during blood glucose testing. The lancing device is the reusable, handheld tool that holds and controls the lancet, while the lancet itself is the small, sterile needle used to prick the skin and produce a drop of blood for testing. Unlike the lancing device, most lancets are designed for single-use and should be replaced regularly to help keep testing reliable and hygienic.

Key Features to Look For in a Lancing Device

To get the most out of at-home testing, it’s important to choose a lancing device that feels comfortable, convenient, and easy to use. Since blood sugar checks can become part of the care routine, paying attention to the right features can help you select a device that meets your needs.

Adjustable Depth Settings

Adjustable depth settings help to produce enough blood for testing without causing more discomfort than necessary.

Most quality lancing devices offer adjustable depth settings, some going up to 13 levels 2 , so users can personalize testing based on comfort level and skin type. People with sensitive or thinner skin, including children, often prefer lower settings, while thicker or more callused skin may need deeper settings for an accurate reading.

To stay consistent with routine blood sugar tests, choosing features designed for gentler testing can make testing more manageable.

Lancing Devices - Ease of use and Lancet Loading

Comfort and Pain Reduction

To stay consistent with routine blood sugar checks, choosing features designed for smoother testing can make daily checks easier to manage. Fine-gauge lancet compatibility allows the device to work with thinner lancets that create smaller skin punctures and may help reduce discomfort during testing 3. A smooth spring action and ergonomic grip can also help fingerstick checks feel steadier and more comfortable to perform.

Ease of Use and Lancet Loading

The easier a lancing device is to use, the more manageable routine blood sugar checks can feel. Some devices offer one-handed loading or drum-style cartridge systems, like Accu-Chek FastClix, with multiple preloaded lancets to reduce the need to handle individual lancets for every check. Easy lancet ejection can also improve safety and simplify cleanup by limiting contact with used lancets, which is important for users with arthritis or reduced dexterity.

Lancet Compatibility

Most lancing devices use universal lancets, but some are designed to work with lancets made specifically for that system. The Microlet Next is compatible with Microlet lancets, which are engineered to fit the device securely for a smoother, more controlled fingerstick experience. This can make your routine checks feel a little more straightforward with less adjusting or fumbling during setup.

Hygiene and Safety Features

Keeping fingerstick testing hygienic can help make routine checks safer and more comfortable over time. Using a new, sterile lancet for each check helps keep the needle clean and sharp, since reused lancets can become dull and less comfortable with repeated use 4. Some lancing devices also include no-touch or easy-eject features to make cleanup simpler.

Types of Lancing Devices

Lancing devices are designed to make routine blood sugar tests safer and more comfortable to perform. Some may be single-use, while others are reusable, with your preferred option often depending on your testing habits, comfort preferences, and what feels simplest for your needs.

Reusable Lancing Devices

Reusable lancing devices are designed for long-term use and are commonly chosen by people who check their blood sugar regularly. These devices support a more consistent and cost-effective testing routine for people with Type 1 Diabetes or Type 2 Diabetes who may test multiple times a day.

Single-Use Lancing Devices

Single-use (safety) lancing devices are designed for one-time use and are commonly preferred in hospitals, clinics, or by individuals who test less often and want a quick, ready-to-use solution. Because the lancet is discarded after each check, these devices can help reduce the risk of accidental injuries and cross-contamination.

How to Use a Lancing Device (Step by Step)

Using a lancet device correctly can make blood sugar tests more comfortable, while supporting accurate results and lowering the risk of injury. Most lancing devices are typically used in the following ways:

  1. Wash and dry your hands thoroughly before testing to prevent contamination.
  2. Remove the cap of the lancing device and insert a new sterile lancet.
  3. Twist off the lancet cover, then securely replace the device cap.
  4. Adjust the depth setting based on your comfort needs and skin thickness.
  5.  Prime the device according to the manufacturer’s instructions.
  6. Choose a puncture site, usually along the side of your fingertip, which may feel less sensitive than the center.
  7. Place the device firmly against your skin, then press the release button to collect a small blood sample.
  8. Collect the blood sample for testing, then safely eject and dispose of the used lancet afterward.
