Part 37: Fingerstick capillary puncture

Описание: In this video, we’re going to walk through a 2025-standard fingerstick capillary puncture workflow—a detailed 23-step procedure designed to protect patient safety and ensure specimen integrity from start to finish.

We’ll begin with the foundations that prevent serious errors: positive patient identification, correct test verification, and aseptic site preparation. Then we’ll move into proper lancet selection and application, including how to choose the safest site and technique for the patient in front of you.

You’ll learn the key microcollection techniques that make a big difference in accuracy:

Why you must wipe away the first drop of blood

How to follow the correct capillary order of draw to prevent contamination and clotting

How to collect without causing hemolysis or tissue-fluid dilution from excessive squeezing

We’ll also cover the safety rules that change by age group—what sites are appropriate for adults versus infants and children—and why engineered sharps devices are essential for modern compliance and needlestick prevention.

By the end of this lesson, you’ll have a repeatable, step-by-step fingerstick process aligned with current safety expectations—helping you minimize preanalytical errors and avoid common complications while producing reliable capillary specimens.
