Difference between anticoagulant tube and non anticoagulant tube and preservation time of blood sample

 

When we enter the hospital for blood test, we will find that there are obvious differences in the color of the blood vessels used. In fact, this is because the medical staff need to distinguish the items to be tested by different colors. Generally, the test tubes containing anticoagulants are purple. After anticoagulation test, it takes about 1-3 days for patients to get the results. How long does it take to get the results without anticoagulants? What is the difference between the two? Here's a detailed introduction.

 

Difference between anticoagulant tube and non anticoagulant tube

 

In order to prevent blood clotting, anticoagulants are mainly added to the anticoagulant tube. The existence of anticoagulants in the tube provides convenience for medical staff and is widely used in blood detection and biological experiments. The difference between it and the test tube without anticoagulant is the coagulation state of blood. The inside of the anticoagulant test tube can ensure that the blood sample remains in its original state without coagulation, while the test tube without anticoagulant generally has the effect of vacuum blood drawing, without other functions, its blood will be in a coagulation state within a certain period of time. In addition, from the results of blood precipitation, plasma can be obtained in the anticoagulant tube, while serum can be obtained in the tube without anticoagulant.

 

Time of blood sample preservation in anticoagulant tube

 

The anticoagulant tube used in the process of blood testing can not only play an anticoagulant role, but also preserve blood after collecting blood samples. How long is its storage time? Generally, the storage time of test tube blood samples containing anticoagulants is mainly determined by anticoagulant reagents. The types of anticoagulants are complex, including heparin anticoagulants, EDTA potassium salt anticoagulants and sodium citrate anticoagulants. These products are of different types, with different testing items and storage time.

 

If the test item is a routine blood test, it can be stored for about a week in an environment of 2-8 degrees. If it is a biochemical test, it usually needs to be completed within 12 hours. If it is a blood glucose test, it may be inaccurate if it takes more than 2 hours without adding other reagents or refrigeration, so it needs to be completed quickly as soon as possible.
