What is the additive in the Light Green Tube Top?

The Light Green Tube Top contains Lithium Heparin as its additive, which serves a specific purpose in laboratory testing. Lithium Heparin is an anticoagulant that helps to prevent the clotting of blood samples by inhibiting thrombin and factor Xa, making it particularly useful for tests requiring plasma. This allows for timely and accurate analysis of certain blood components without the interference of clotting factors.

In contrast to other additives such as Sodium Fluoride, Potassium Oxalate, and EDTA, each of which serves different functions and is used in different types of samples or for different tests, Lithium Heparin is specifically designed for the collection of plasma for biochemical tests. This distinction makes it crucial to understand the purpose of each additive to ensure proper handling and testing in a phlebotomy context.
