2. EDTA helps preserve the blood cells and prevent clotting.

Green Top Tubes

1. These tubes contain the Anticoagulant Heparin and are used for tests that require plasma.
2. Heparin prevents the blood from clotting by inhibiting thrombin formation.

Blue Top Tubes

1. These tubes contain the Anticoagulant Sodium Citrate and are used for coagulation tests.
2. Sodium Citrate binds calcium ions, preventing the blood from clotting during testing.

Importance of Proper Handling

Proper handling of blood collection tubes is essential to ensure the accuracy and reliability of Test Results. Some key points to keep in mind include:

Labeling
