1) To prevent clotting of blood
2) To ensure accurate test results
3) To maintain the integrity of the sample
4) All of the above

Answer 1

Mixing anticoagulant tubes immediately after filling is important to prevent clotting, ensure accurate test results, and maintain the integrity of the sample.

Step-by-step explanation:

It is important to mix anticoagulant tubes immediately after filling them for all of the above reasons.

1) To prevent clotting of blood: Anticoagulant tubes contain substances that prevent the blood from clotting, such as EDTA or heparin. Mixing the tubes immediately after filling ensures that the anticoagulant is evenly distributed and prevents the formation of blood clots.

2) To ensure accurate test results: If the blood sample is not mixed properly, any clotting that occurs during storage can interfere with laboratory tests and lead to inaccurate results. Mixing the anticoagulant tubes minimizes the risk of clot formation and ensures the integrity of the sample for accurate testing.

3) To maintain the integrity of the sample: Clotting can alter the composition of the sample, affecting the concentration of certain substances and potentially leading to inaccurate test results. Mixing the anticoagulant tubes immediately after filling helps maintain the integrity of the sample by preventing clot formation and maintaining the stability of the blood components.
