TUBE PST II LITHIUM HEPARIN 4.5ML

BD Vacutainer® PSTTM II Tubes
Plasma tubes with separating gel for clinical chemistry
are available with spray-dried lithium heparin additives.
During the centrifugation of the BD Vacutainer® PSTTM II
Tubes, an inert gel separates the serum and the blood clot preventing the contamination of the plasma from the separated cellular components. For example, the plasma for certain analytes such as potassium, phosphorus and glucose must be separated from the cells within a few hours – otherwise the results will be significantly distorted.

Using BD Vacutainer® PSTTM II Tubes routine analytes in clinical chemistry such as potassium and glucose are still stable after a week of storage at 2-8ºC. Clinical evaluation of special chemistries such as therapeutic drugs, proteins, peptides, steroids and vitamins demonstrates a high degree of stability.

The main advantages of gel tubes versus non-gel tubes are:
• Stable barrier between plasma and red blood cells, therefore better analyte stability
• Better sample quality
• Optimisation of the work flow: short centrifugation time,
sample processing and archiving in the primary tube
• No possibility of confusion due to the use of secondary tubes

Effects of temperature:
BD Vacutainer® PSTTM II Tubes should be stored at 4-25°C and protected from direct sunlight during storage. Coolingof the tube by or during centrifugation can affect the movement. The optimum separation of sediment and plasma is achieved at a temperature of 20-25°C.

Mixing the tube:
Correct mixing (8-10 inversions) of the BD Vacutainer® PSTTM II Tube immediately after the blood sample has taken is extremely important to avoid microclotting.
