Precautions for disposable vacuum blood collection tubes

Precautions for use of disposable vacuum blood collection tubes include:

1. Do not shake the sample during collection to prevent hemolysis.

2. Add as few preservatives as possible to avoid destroying cell morphology.

3. Send for testing as soon as possible to prevent cell rupture.

At the same time, in order to ensure the accuracy of the test results, do not press the blood collection tube locally after blood is drawn, otherwise blood coagulation is likely to occur, affecting the test results. In addition, do not repeatedly raise your hands during the pressing process, as this may cause the blood in the blood collection tube to flow back due to gravity, thereby contaminating the entire test tube and making the specimen invalid.

If you feel needle phobia or slight dizziness, you need to rest for a while and then observe. After confirming that there is no abnormality, use a vacuum blood collection tube to draw blood. This ensures the safety and accuracy of the entire collection process. These are the things you need to pay attention to when using disposable vacuum blood collection tubes.
