Capillary blood sampling is a medical procedure used for early detection of some diseases before their symptoms appear or serious complications arise and for routine checking the health status of patients.

In adult patients, a blood sample is obtained by simple pricking of a finger. The technique has been used for decades and it is progressively used worldwide because it is a quick, easy, cheap, and widely available method to check and control a patient’s status of health.
