capillary blood collection
Capillary blood collection is a method used to obtain small amounts of blood, typically from a fingertip or heel in infants. It involves using a sharp, small device called a lancet to make a quick, shallow puncture in the skin. This allows blood to flow out, which can then be collected with a small tube or test strip. This technique is often used for quick tests like blood sugar monitoring or newborn screenings, as it's less invasive than drawing blood from a vein and requires minimal equipment. It's a common practice in both home and clinical settings.

Capillary blood collection is a method used to obtain blood samples from the tiny blood vessels, or capillaries, just under the skin's surface. This process usually involves pricking a finger or heel with a small, sterile device. It's commonly used for quick tests, like checking blood sugar levels or conducting newborn screenings, since it requires only a small amount of blood. Capillary samples can provide important information about a person's health and are often less invasive and easier for patients, particularly children, than traditional blood draws from veins.
