Blood Sample Tube PST II Light Green Cap 4.5ml - Box of 100

BD Vacutainer® PSTTM II tubes

These tubes contain an inert gel barrier and spray-dried lithium heparin additive. The inert barrier separates the plasma from the blood cells during centrifugation, preventing contamination of the plasma. For example, in plasma certain analytes such as potassium, phosphorus and glucose should be separated from the cells within a few hours, otherwise the results will be significantly impacted. Using BD PSTTM II tubes, routine analytes in clinical chemistry such as potassium are still stable after 24 hours storage at 2-8ºC. Clinical evaluation of special chemistries such as therapeutic drugs, proteins, peptides, steroids and vitamins demonstrates a high degree of stability within the BD PSTTM II1,2,3.

• Stable barrier between plasma and clotted blood during transportation and storage, therefore better analyte stability.
• Better sample quality.
• Optimisation of the work flow: short centrifugation time, sample processing and archiving in the primary tube.
• No requirement for secondary tubes, reducing the possibility of misidentification.
