Serum Blood Collection Tube

In the clinical medical experiments using human venous blood as specimen, some take the serum from the specimen as the experimental object. The blood collection tubes suitable for this type of medical tests are called serum blood collection tubes.

The Basic Functions of Serum Blood Collection Tubes

1. To collect peripheral venous blood enough for the serum required in test. 

2. Within the specified time, to process it into blood coagulation and extract complete serum or platelet poor serum under the force of centrifuge.

3. Within the specified storage period of specimen, to guarantee no variation or pollution to the biotic and chemical composition of serum. 

The blood collection tubes meeting the above functions include the three types of additive-free, clot activator and separation gel/clot activator (respectivelyred cap, orange cap and yellow cap).
