Nov 27, 2017  Source of sample. Capillary blood has higher hemoglobin than venous blood, especially in women and in men with severe iron depletion (median 0. 67 gdL for irondepleted women to 0. 1 gdL for irondepleted men). 3 Venous blood has a slightly higher hemoglobin concentration than arterial blood. Sampling site.

Capillary blood (fingerstick) sampling is increasingly being used worldwide due to the growing availability of pointofcare (POC) testing.capillary blood sample sites The blood may be collected in a pipette (or small glass capillary tube), on a slide, onto a test strip, or into a small container. Cotton or a bandage may be applied to the puncture site if there is any continued bleeding. Difference in Results of Capillary Blood Sample from Other Methods. The differences between capillary blood versus plasma in most cases are minimal.

Capillary blood is obtained from capillary beds that consist of the smallest veins (venules) and arteries (arterioles) of the circulatory system. The venules and arterioles join together in capillary beds forming a mixture of venous and arterial blood. capillary blood sample sites Ring finger, great finger, earlobes, lateral sides of heels on infants Generally appropriate site to collect a capillary blood sample from a site that is Warm, free of bruises, scars, lesions, edema 2 mm into site Oct 15, 2015  Capillary blood sampling is associated with several disadvantages, many of which can lead to greater risk of false test results. A capillary blood sample contains unknown proportions of blood from venules, arterioles and capillaries. Capillary blood samples can also be contaminated to unknown extents by interstitial and intracellular fluid. In fact, capillary blood is often sampled into multiple microcollection devices at the same time and from the same puncture site sample. 16 For collectors already familiar with fingerstick blood collection for other purposes (e. g. , hematocrit or CBC), there is a tendency to not agitate the blood sample too strongly lest the red blood cells rupture. For blood lead tests vigorous agitation is not an issue because it is more important to prevent clotting than cell rupture. Venous and capillary blood are not the same and the differences is related to biological variability. Blood from a skin puncture is a mixture of blood from arerioles veins and capillaries, containing interstitial and intracellular fluid. According to literature search, no general statement can be made on how the hemoglobin concentration and white blood cell counts are effected by sample site.
