Related Faqs

Is a discard tube needed if the only tube being collected is a coagulation tube?

There have been recent articles indicating that drawing a discard tube is not necessary before drawing the sodium citrate tube. In the CLSI coagulation document (H21-A5) it is still recommended that the citrate tube is the second or third tube drawn. However, in the CLSI guideline for Venipuncture Collection (H3-A6) it states that for routine PT and APTT, the first tube drawn may be used for testing.It is also important to ensure a discard tube is drawn when a blood collection set is used and only a citrate tube is ordered, as the tubing may contain up to 0.5 mL of air that will be drawn into the tube and displace blood volume.

At what temperature should the Blood Collection Tubes be stored?

GBO tubes should be stored at 4-25°'C (39-77°F).

Can Blood Collection tubes be re-sterilized, for introduction into a sterile field?

VACUETTE® Tubes are irradiated to achieve sterility. These tubes are sterile on the interior only. We cannot recommend re-sterilizing the tubes, primarily due to pressure changes that take place during the re-sterilization cycle. Our tubes are under a specific negative pressure. During the re-sterilization cycle this negative pressure may be disrupted and therefore the tubes may not draw the proper blood volume.

Are VACUETTE® Blood Collection Tubes endotoxin free?

No, GBO does not claim that any of the tubes are endotoxin free.

Why is there an expiry date on VACUETTE® Tubes?
