What is the advantage of using plastic capillary tube when collecting blood?

The main advantage of using plastic capillary tubes for blood collection is their ability to minimize contamination and ensure a controlled sample volume. Additionally, they are lightweight and less prone to breakage compared to glass tubes, making them safer and more convenient for handling. Plastic capillary tubes also promote faster clotting, which can be beneficial for certain diagnostic tests. Overall, these features enhance the efficiency and safety of blood collection procedures.
