You are required to draw blood from a patient and to keep it in a test tube for analysis of blood corpuscles and plasma. You are also provided with the following four types of test tubes. Which of them will you not use for the purpose?
Chilled test tube
Test tube containing heparin
Test tube containing sodium oxalate
Test tube containing calcium bicarbonate
The Correct Option is D
Solution and Explanation
When performing blood analysis for blood corpuscles and plasma, it is crucial to choose the correct type of test tube to ensure accurate results. Let's analyze the options provided:
- Chilled test tube: Typically used to slow down metabolic processes. It can be useful in preserving the integrity of the sample for certain types of biochemical analysis, but it does not directly interfere with blood clotting.
- Test tube containing heparin: Heparin is an anticoagulant that prevents blood from clotting. This is suitable for plasma analysis as it helps maintain the sample in its liquid state without clot formation.
- Test tube containing sodium oxalate: Another anticoagulant that prevents calcium in the blood from participating in the clotting process, hence preventing clot formation. Useful for analyzing blood corpuscles and plasma.
- Test tube containing calcium bicarbonate: Calcium bicarbonate does not function as an anticoagulant. In fact, calcium plays a crucial role in blood clotting, as it’s a part of the clotting cascade. Using a tube with calcium bicarbonate can promote clotting, which would not be suitable for analyzing plasma.
Thus, the test tube that should not be used for blood analysis of corpuscles and plasma is the one containing calcium bicarbonate. It would lead to clot formation, thereby compromising the analysis.
