What is the difference between a finger stick and a venipuncture?

What is the difference between venipuncture and capillary puncture?
Capillary blood sampling is becoming a common way to minimize the amount of blood drawn from a patient. The 10 or 20 microliters can be used to look for anemia, check blood sugar or even to evaluate thyroid function. The procedure is easier and less painful than traditional venipuncture which draws blood from a vein.

Finger stick tests may also be performed by a healthcare professional for assisted monitoring of blood sugar.
What type of blood is drawn when performing a fingerstick?
In medicine, some blood tests are conducted on capillary blood obtained by fingerstick (or fingerprick) (or, for neonates, by an analogous heelprick). The site, free of surface arterial flow, where the blood is to be collected is sterilized with a topical germicide, and the skin pierced with a sterile lancet.
Which is better, A venipuncture or a finger stick?
Venipuncture specimens are superior to those collected by fingerstick because the risk of environmental contamination is minimal and a larger volume of blood is obtained for analysis. For this reason, venipuncture should be utilized for specimen collection whenever possible.
How is the fingerstick used to extract blood?
