McKesson 21G Pressure-Activated Safety Lancets
McKesson 21 Gauge Pressure-Activated Safety Lancets – 2.0 mm (100 per Box)
Overview
McKesson Pressure-Activated Safety Lancets fire by contact rather than a button — simply hold the lancet against the fingertip and press down gently, and the needle deploys automatically, then retracts and stays concealed before and after use. With no button to press and nothing to load, they're a simple, one-step option that many find easier for single-handed use, making them a practical choice for home routines and professional or multi-user stations alike.
This 21 gauge version at a 2.0 mm depth is the highest-flow option in the pressure-activated range, drawing a full, normal blood sample on the first try. Its tri-bevel needle suits standard capillary tests that need a fuller drop — such as blood glucose, hemoglobin, and similar fingertip sampling.

This 21 gauge is the highest-flow option in the pressure-activated range — the thickest needle and deepest 2.0 mm setting, for a full blood drop on the first stick. It's the one to reach for when a test needs a fuller sample or when finer gauges aren't drawing enough. The contact activation is the shared advantage across the line: no button to push, so it fires the moment you press it firmly to the fingertip. Step down to the 26 gauge for a standard draw or the 30 gauge for the gentlest, smallest sample. For higher-volume settings, the case keeps a steady supply on hand.

What is the 21 gauge / 2.0 mm best for?
It's the highest-flow option in the pressure-activated range — the thickest needle and deepest depth, for a full blood drop. That makes it a good fit for standard capillary tests that need a fuller sample, such as blood glucose and hemoglobin sampling.
How is pressure-activated different from push-button?
There's no button to press. You hold the lancet firmly against the fingertip and press down, and it fires automatically once enough contact pressure is applied. Many people find that easier to manage one-handed and less intimidating than pressing a trigger.
Do I need a separate lancing device?
No. This is a self-contained, ready-to-use safety lancet — nothing to load or assemble. Press it to the site to activate, and the needle retracts and stays concealed afterward.
