How to use disposable vacuum blood collection tubes

The usage of disposable vacuum blood collection tube is as follows:

1. Preparation before collection: Wash your hands and check whether the vacuum blood collection tube is intact to avoid puncture.

2. Collect blood: Insert a blood collection tube into the blood vessel chamber, then use a three-edged needle or blood collection needle to pierce the skin and allow the blood to flow out naturally. The blood will automatically flow into the blood collection tube without causing blood coagulation.

3. Separate serum: Gently rotate the blood tube to evenly distribute the blood on the tube wall, then let it stand for a few minutes. After the serum is naturally separated, use a small pipette to absorb the serum.

4. Preserve serum: Store the serum in a refrigerator and return it to room temperature when needed for further testing.

In addition, please note the following points:

1. Avoid contamination: Avoid blood contamination during operation to avoid affecting the test results.

2. Timely processing: Do not put the used blood collection tube back into the tube barrel to avoid affecting the next use.

3. Note: During the blood drawing and testing process, the blood collection tube must be kept airtight to avoid affecting the collection and separation of serum.

In short, the use of disposable vacuum blood collection tubes needs to follow the correct steps and pay attention to avoid contamination and timely disposal.
