9+ Tests: Lithium Heparin Tube Used For?

Lithium heparin tubes are specialized blood collection devices coated with lithium heparin, an anticoagulant. They prevent blood from clotting, allowing for the separation of plasma, which is then analyzed. This type of tube is frequently utilized when plasma samples are required for various laboratory analyses. For example, a lithium heparin tube may be used to collect blood samples for a comprehensive metabolic panel.

The use of lithium heparin tubes offers several advantages. The resulting plasma is generally less prone to interference compared to serum, which is obtained from clotted blood. Historically, heparin has been a preferred anticoagulant in clinical chemistry due to its minimal impact on enzyme activity. This has made it crucial for obtaining accurate and reliable results, particularly in time-sensitive diagnostic settings.
