capillary blood is the mixture of venous and arterial blood... A capillary sample is a blood sample collected by pricking the skin. Capillaries are tiny blood vessels near the surface of the skin.Capillary blood sampling offers several advantages:
- It is relatively easy to obtain (it can be difficult to obtain blood from the veins, especially in infants).
- There are several collection sites on the body (heel, fingertips, etc.) and these can be rotated.
- Testing can be performed at home and with minimal training. For example, diabetics must check their blood sugar several times a day using capillary blood sampling.
