McKesson Prevent HP Safety Lancets 21G 1.8mm
McKesson Prevent HP Push-Button Safety Lancets – 21G / 1.8 mm (100 per Box)
Overview
McKesson Prevent HP Push-Button Safety Lancets are the safety-engineered option in the McKesson lancet range, built around the HP-Haemolance Plus design. The needle is enclosed before use, fires at the press of a button, then automatically retracts and locks out — so the sharp is never exposed before or after sampling. That makes them especially well suited to professional and multi-user stations where safe sharps handling is a priority, while staying simple enough for everyday home routines.
This 21 gauge version uses the thickest needle in the Prevent HP fingertip range, paired with a 1.8 mm depth — a combination built to draw the fullest, most reliable blood drop in the line. It's the one to reach for when a test calls for a larger sample or when finer needles simply aren't producing enough on the first stick.
Key Features
- HP-Haemolance Plus design — automatic needle retraction and lock-out keep the needle enclosed before and after use.
- Helps prevent accidental needlestick and supports safe, hygienic single-use handling.
- Push-button activation with a simple, intuitive operation — no loading required.
- Tri-beveled 21 gauge needle at a 1.8 mm fixed depth — the highest-flow gauge in the Prevent HP finger range.
- Built for a fuller blood drop when a larger sample is needed.
- Green color-coded body for quick gauge identification.
- Sterile, single-use; not made with natural rubber latex.
- 100 lancets per box; available by the case for higher-volume settings.
At 21 gauge this is the thickest needle in the Prevent HP finger line, so it delivers the fullest blood drop of the range — the one to choose when a test needs more sample or when finer gauges aren't drawing enough. The trade-off is that a thicker needle isn't the gentlest, so for light everyday fingersticks the 25 or 28 gauge options are more comfortable. Matching the gauge to the sample you actually need is the key. The lock-out safety mechanism is identical across the line, and the case quantity keeps a steady supply on hand for higher-volume settings.

What is the 21 gauge best for?
It's the highest-flow option in the Prevent HP finger range. The thicker needle and 1.8 mm depth draw the fullest blood drop in the line, which helps when a test needs a larger sample or when finer gauges aren't producing enough on the first stick.
What makes Prevent HP different from a standard safety lancet?
The lock-out. After firing, the needle automatically retracts and locks away, so it stays enclosed both before and after use. Combined with the tri-beveled needle, it's geared toward safe handling in shared and multi-user settings.
Is this a good everyday fingertip lancet?
It can be, but because it's the thickest, highest-flow option it isn't the gentlest. For light routine fingersticks, a finer 25 or 28 gauge lancet is more comfortable; choose the 21 gauge when you specifically need a larger blood drop.
