How to use blood collection tube

1. Orange tube cap (biochemical tube):
The tube contains a coagulant (to promote rapid blood coagulation and facilitate the precipitation of serum for later use), which is used to draw biochemical samples. The volume is 5 ml. It is automatically controlled. However, due to quality problems, attention is needed. If automatic control is not possible
System, it requires artificial control.
Note: After the blood is collected, it can be slightly inverted for 1 to 2 times without shaking.
2.Purple tube cap (blood routine tube):
Contains EDTANa-2 anticoagulant, which is specially used to draw blood routine specimens. The volume is 2ml. It is automatically controlled. However, pay attention to observation. If it is more than 2ml, if it still does not stop, the blood sampling will be stopped artificially (pull out the tube to collect blood)
Needle), and then take another tube.
Note: After the blood is collected, turn it upside down slightly for 6 to 7 times without shaking.
3. Blue tube cap (blood coagulation mechanism tube):
Contains sodium citrate anticoagulant, which is specially used to draw blood coagulation mechanism (coagulation complete set), the volume is automatically controlled by 1.8 ml, otherwise the treatment is the same as above.
Note: After the blood is collected, turn it upside down slightly 6 to 7 times
4. Black tube cap (erythrocyte sedimentation tube):
Contains sodium citrate anticoagulant (but the ratio is different from that of the blue cap tube), which is dedicated to the collection of erythrocyte sedimentation specimens.
The amount is 1.6 ml, and it is automatically controlled, otherwise the treatment is the same as 1 and 2 above.
Note: After the blood is collected, turn it upside down slightly for 6 to 7 times without shaking.
