The separation gel in the disposable vacuum blood collection tube mainly plays the following roles:
Promoting blood coagulation: The coagulant in the blood collection tube can quickly activate the coagulation factors in the blood, causing the blood to coagulate rapidly. This helps to obtain cell-free serum within a short period of time for subsequent analysis.
Separating serum and blood cells: The separation gel is an inert colloid that, through the action of centrifugal force, separates the serum from the blood cells. This type of separation gel usually has a moderate specific gravity, which allows it to stably locate between the serum and blood cells during centrifugation, thus achieving their separation.
Maintaining sample quality: The combined action of the separation gel and coagulant effectively prevents blood from clotting during collection while preserving the original state of the blood sample, thereby ensuring the accuracy of detection results.
Improving detection efficiency: By promoting rapid coagulation and effective separation, the separation gel coagulant can significantly shorten sample processing time and improve laboratory work efficiency.
In summary, the role of the separation gel coagulant in disposable separation gel vacuum blood collection tubes is primarily to promote blood coagulation, separate serum and blood cells, maintain sample quality, and enhance detection efficiency. These properties have led to widespread application of such blood collection tubes in clinical and laboratory diagnostics.
