Glass matters.

Historically, glass has been the preferred material for capillary tubes used to collect blood-gas samples. There is, however, potential risk of injury and/or infection due to accidental breakage of glass capillary tubes. In addition, the flexible nature of some non-glass devices can result in aerosol formation and specimen loss if the tube should be bent or bumped during collection, transport, or testing. Now, we have Mylar-wrapped glass capillary tubes that have been treated with calcium-balanced lithium heparin to prevent the sample from clotting. The Mylar minimizes risks associated with broken glass capillaries by containing both the glass and the sample in the event of accidental breakage.
