What Is a Lancet?
A lancet is a small sterile needle used to obtain the blood sample you need to check your blood sugar. Lancets can be used on their own or in conjunction with a lancing device, and they come in many sizes.
The length of a lancet is measured in millimeters (mm). However, the length doesn't necessarily reflect how deeply the lancet will puncture your skin, as lancing devices typically allow you to set the degree of puncture.
Lancet size makes a difference when it comes to monitoring blood glucose levels. If you need only a small blood sample, you may choose a smaller lancet, whereas you may need a larger lancet if a larger blood sample is required. However, lancet size is not the only factor to consider; shape and sharpness can also affect your experience.
Different Types of Lancets
There are several different types of lancets and lancing devices on the market, and each offers unique features.
Traditional
A traditional lancet has a sterile needle attached to a plastic part that connects to a lancing device. The plastic piece holds the needle in place for stable handling. Traditional lancets differ in style and functionality. Examples include the following:
Exposed needle with a handle for a safe grip
Needle is exposed by pulling a protector off the top
Needle is exposed by twisting the top off
Traditional lancets should be disposed of in a sharps container after each use. Reusing the same lancet can dull the needle, make obtaining a blood sample more painful, and increase the risk of infection.
Safety
A safety lancet has a sterile, retractable needle that deploys only when activated by the user. Before activation, the needle is covered, which prevents accidents. These lancets were designed to comply with federal occupational safety regulations applicable to clinics but may be purchased by people living with diabetes for at-home blood glucose management.
Safety lancets are encased in their own lancing devices, which come in an array of designs. For example, a safety lancet may be spring-loaded and activated with the push of a button. It can also be part of a passive device activated only by pressure or contact with the sample area. Many passive devices come with a fixed penetration depth and have a self-destructing activation mechanism that makes it impossible to reuse the lancet.
Replaceable

Replaceable lancets are sterile, disposable lancets used with a reusable lancing device.
Specialty
Specialty lancing devices may require unique lancets.
Different Types of Lancing Devices
Which type of lancet you use will largely depend on the lancing device. Most lancing devices fall into one of the following categories:
The user holds the lancing device in one hand and lances a finger on the opposite hand. Since the introduction of more comfortable and safer options, these devices are rarely used.
These devices are used with safety lancets and are discarded after use.
This is the kind of lancing device usually included with BGM devices. While the device is used repeatedly, the lancet is replaceable and should be discarded after each use. Reusable lancing devices may have a variety of features to improve the user experience, including depth adjustment.
Specialty lancing devices, such as vacuum devices, electronically controlled devices, and laser devices, have unique features that aim to improve the blood collection process. In the case of laser devices, no needle is used.
Today, there are more devices available than ever before, giving you new ways to optimize comfort and convenience. One of the most innovative is the POGO Automatic® Monitor.
POGO Automatic Makes Lancing Simple
With its integrated lancing, the POGO Automatic Monitor offers a safe, fast, and convenient way to check your blood sugar levels. Rather than relying on separate test strips and lancets, it uses ten-test cartridges that contain test strips and lancets. The POGO Automatic automatically lances and collects blood at the push of a button and returns results within seconds.
The innovative design of the POGO Automatic helps prevent accidental pricks, much like a safety lancet. It requires a blood sample size of only .25µL. That's about the size of a pinhead and smaller than the standard .3'.6mµL samples required by traditional BGM systems.
Some information about our bodies can only be discovered through blood tests. Tests that are performed at home often need a finger prick to draw blood. People who have diabetes and don't have a continuous blood glucose monitor may need to prick their fingers several times a day. This can become painful, which may cause you to avoid checking your blood sugar as often as you should.
A finger prick is a method of drawing drops of blood for at-home medical tests. These are most commonly used by people with diabetes to check their blood sugar (blood glucose) levels, but can also be used in other at-home test kits, such as tests for sexually transmitted diseases or hormone levels.
Finger pricks, also called finger sticks, are done using a device called a lancet. Lancets are needles or narrow, sharp blades that poke a small hole in the skin. There are two types of lancets used for collecting blood samples:
Never share your finger prick lancets with anyone, as this can spread bloodborne diseases.
