Show Capillary blood collection has been around for decades. When it began, the technique was used to obtain blood from infants for genetic screening. Drawing a volume of five or ten µl from a newborn baby can be difficult and potentially harmful, so small-volume sampling had obvious applications in this area. Capillary blood is obtained by pricking a finger in adults and a heel in infants and small children. The specimen is then collected with a pipette, placed on a glass slide or a piece of filter paper, or is absorbed by the tip of a microsampling device. Capillary blood is used for glucose measurements by transferring the blood to a test strip. Differences in Results The differences between capillary blood versus plasma in most cases are minimal. However, there are some discrepancies in hemoglobin and hematocrit values and in platelet counts. Glucose levels also have a small disparity. Venous blood glucose is generally slightly higher than capillary blood glucose measured at the same time. These laboratory reports need to be evaluated in light of the sampling method used.

Collection
In general, capillary blood collection is much preferred by both end-users and lab technicians. The method is simpler, less painful, and rarely requires a "second stick." Results are comparable between capillary blood versus plasma except in a few cases. In those cases, the results need to be correlated with data from the same collection method.

Which of the following sites is commonly used to collect a capillary blood sample?The finger is usually the preferred site for capillary testing in an adult patient. The sides of the heel are only used in paediatric and neonatal patients. Ear lobes are sometimes used in mass screening or research studies.
