Lancets are small devices that provide a way to take blood samples. People with diabetes may use a lancet to test and monitor their blood glucose levels. Regular testing can help people manage their diabetes symptoms.
A lancet is a small, sharp, spring-loaded device that takes small blood samples. People usually perform a finger prick to take the sample.
Lancets are normally disposable, and they are only suitable for single use. However, a person may have a lancet device that holds multiple disposable lancets.
To use a lancet, a person swabs their finger with an alcohol swab. Then, they apply pressure to their finger with the lancet, and the device will automatically trigger. Occasionally, a person may need to press a button to activate the device.
Various tests may require a finger prick sample.
People with diabetes are most likely to need to use lancets to monitor their blood glucose levels. They typically need a blood glucose monitor and a lancet device to do this.
Various at-home tests, such as allergy tests and sexually transmitted infection tests, may require a lancet to draw a small blood sample. Most at-home tests include a lancet in the kit.
Some factors that a person may wish to consider before making a purchase include:
- Needle size: The higher the number of the needle gauge size, the smaller and thinner the needle is. A person may find that thinner needles do not penetrate the skin as easily as thicker ones.
- Brand: If a person has a refillable lancet device, they must ensure that they select the correct brand and style of lancet to put inside it.
- Thickness: The thickness of the lancet also varies between models. Usually, the thinner the lancet, the less discomfort a person experiences when taking the sample.
- Lancet depth: One 2020 study asked participants to use a lancing device at different depth settings. The researchers found that blood volume and pain levels were higher when at the maximum lancing depth.
- Device: Some people may find it easier to use a lancet device rather than a lancet on its own.
- Sample location: People who regularly monitor their blood glucose levels may get sore fingertips from regular lancing. Some lancing devices are suitable for use on other parts of the body.
There are various types of lancets available to buy online. Some have different penetration depths, can take several samples, or may help prevent pain and bleeding.

When a person has diabetes, their body may not make enough insulin or use insulin as well as it should. Insulin controls blood glucose levels in the human body.
The American Diabetes Association says that there are three types of diabetes:
- Type 1: This is where the body does not produce enough insulin.
- Type 2: This is the most common form of diabetes. This is where the body does not use insulin as it well should.
- Gestational: This is a type of diabetes that develops during pregnancy.
People with diabetes should monitor their blood glucose levels regularly with lancets and lancing devices. A person’s medical team will tell them how often they should check their blood glucose levels.
Once a person has taken a blood sample using a lancet, they need to apply the blood to a test strip and run it through a blood glucose monitor.
A person who has symptoms of diabetes should make an appointment with a doctor as soon as possible.
