capillary blood sampling
Capillary blood sampling is a method used to collect a small amount of blood, typically from a fingertip or heel, for testing. This technique is often used for quick assessments like blood sugar levels or to obtain samples for newborn screening. The process involves pricking the skin with a lancet to create a tiny puncture, allowing blood to bead up and be collected with a small tube or paper strip. It's less invasive and quicker than drawing blood from a vein, making it a convenient option for routine tests or monitoring.

Capillary blood sampling is a method used to collect a small amount of blood, typically from a fingertip or heel (in infants). This technique is often used for quick tests, like checking blood sugar levels or confirming anemia. A small puncture is made in the skin using a lancet, which allows blood to flow out. It's less invasive and painful than drawing blood from a vein, making it suitable for routine checks and home monitoring. The collected blood is then placed on a test strip or in a small vial for laboratory analysis.
