Principle of Procedure
The BD PPT™ brand tube
provides a means for collection, processing and transportation of
an undiluted plasma specimen in a closed evacuated system. The tube
contains 9 mg of dried K2EDTA, yielding a ratio of 1.8 mg/mL of blood
when the evacuated tube is filled correctly to its 5 mL draw volume.
The tube also contains a material that upon correct centrifugation
(1,100xg for 10 minutes, swing-out bucket rotor) forms a barrier between
the plasma and most of the cellular elements, allowing for transportation
of the BD PPT™ Tube without removal of the plasma. Only the
inside of the tube is sterile. The tube is not pyrogen free.
