  • 1. 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 function include :
    · Additive-free -- red cap,
    · Clot activator-- orange cap,
    · Separation gel/clot activator--yellow cap.

  • 2. Plasma Blood Collection Tube
  • Plasma blood collection tubes are those used to collect plasma specimen in clinical blood testing. As plasma is obtained by removing the cell from uncoagulated blood, it is classified into the types containing free calcium and not containing free calcium. Besides having fibrinogen and anticoagulant, plasma containing free calcium is not quite different from serum in ordinary testing. Therefore, in clinical biochemical laboratory, specimen in this type of blood collection tubes is often used instead of serum. The commonly used plasma blood collection tubes include:
    · Green cap tubes containing heparin sodium salt or lithium salt,
    · Blue cap tubes containing sodium citrate buffer system,
    · Grey cap tubes containing NaF-EDTA composite anticoagulation system.

  • 3. Whole Blood Collection Tube
  • In clinical blood tests, some use flowing blood as specimen, with no need to separate out plasma or cell. The blood collection tubes suitable for such tests are called whole blood collection tubes. The advantage and disadvantage of whole blood collection tubes in clinical application depends on the volume and state of cell maintained by anticoagulation system. Among them:
    · The most representative purple cap tubes,
    · Black cap tubes for blood sediment-action tests,
    · Dynamic blood sedimentation black tubes.
    · Additive-free -- red cap,
    · Clot activator-- orange cap,
    · Separation gel/clot activator--yellow cap,
    · Green cap tubes containing heparin sodium salt or lithium salt,
    · Blue cap tubes containing sodium citrate buffer system,
    · Grey cap tubes containing NaF-EDTA composite anticoagulation system,
    · The most representative purple cap tubes,
    · Black cap tubes for blood sediment-action tests,
    · Dynamic blood sedimentation black tubes.
