Fingerstick
Fingerstick
A Fingerstick (pronounced: /ˈfɪŋɡərstɪk/) is a procedure where a lancet is used to puncture the skin, typically on a person's fingertip, to obtain a small sample of capillary blood for testing.
Etymology
The term "Fingerstick" is derived from the English words "finger" and "stick". It refers to the act of pricking or sticking the finger with a small, sharp object, usually a lancet, to draw blood.
Procedure
The Fingerstick procedure is commonly used in diabetes management for self-monitoring of blood glucose levels. It is also used in various other medical tests that require a small amount of blood, such as cholesterol testing, HIV testing, and hemoglobin testing.
The procedure involves cleaning the fingertip with an alcohol swab, pricking the fingertip with a lancet, and then collecting the blood droplet on a test strip or other collection device. The blood sample is then analyzed using a glucometer or other testing device.
