Blood lancet

Blood Lancet

A Blood Lancet (pronunciation: /ˈblʌd ˈlænsɪt/) is a small medical implement used for capillary blood sampling.

Etymology

The term "lancet" is derived from the Latin lancea, meaning "small spear". This is a reference to the sharp, pointed shape of the tool.

Description

A blood lancet is typically a small, sterile piece of surgical steel or, in some cases, plastic. It is used to make punctures, such as a fingerstick, to obtain small blood specimens. These specimens are typically used for blood glucose monitoring or other blood tests that require only a small amount of blood.

Types

There are two main types of blood lancets:

• Safety Lancets: These are single-use devices with a pre-loaded and retractable blade or needle. They are designed to prevent accidental needlestick injury and cross-contamination.

• Reusable Lancets: These are devices with a reusable holder and disposable lancet. The lancet can be used multiple times before it needs to be replaced.

Usage

Blood lancets are commonly used in the management of various medical conditions that require regular blood monitoring, such as diabetes. They are also used in some types of allergy testing and anemia screening.
