Tubes, Blood Collection, Capillary/Microsample
Definition : Blood-collection tubes designed to draw capillary blood into a microtube usually by capillary action. Typically, when one end of the capillary tube touches the drop of blood, the blood flows up into the tube via capillary effect as long as the other end of the tube remains open. These devices are typically very small size glass or plastic-wrapped glass tubes; filling the length of the tube end-to-end defines a specific amount (usually on the order of microliters) of collected blood. The tubes are usually available as plain tubes or with an internal coating; the type of coating (e.g., an anticoagulant such as heparin) depends on the intended use of the sample being collected, and for this reason the tubes are usually identifiable by the color of the cap. Capillary/microcollection blood-collection tubes are used to obtain samples by skin puncture from a wide range of patient populations, including infants, for serum, plasma, and whole-blood determinations.
