What does Rapid Serum Tube contain?
What does Rapid Serum Tube contain?
BD Vacutainer® Rapid Serum Tubes (RST) contain thrombin-based clot activator and polymer gel for serum separation. Samples processed in these tubes are used for serum determinations in chemistry.
What tube should a thrombin test be drawn in a tube that accelerates clotting?
Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate.
How many times do you invert a BD Vacutainer Rapid serum or RST tube?
Patient Population Specifically, caregivers were instructed to invert the RST 5 times immediately after phlebotomy. No specific instructions or reminders were given for the PSTs, although hospital policy dictates that these tubes should be inverted at least 5 times immediately after phlebotomy.

| Gray | Sodium fluoride, and sodium or potassium oxalate |
Why is serum red after centrifugation?
Depending of the underlying cause, red, icteric or milky appearance are most observed discoloration of the serum or plasma after centrifugation of the sample taken for biochemistry or coagulation testing. In most of the cases, red coloration is a result of in vitro haemolysis (2).
Which tube does not need to be inverted?
All tubes (except red top tubes which contain no additives) must be gently inverted 5 to 8 times immediately after filling, to ensure proper mixing of blood and anticoagulant, or other additives.
What color tube is used for DNA testing?
Preferred Samples. CONTAINER: Purple top (EDTA) tube (preferred). Yellow top (citric acetate) or grey top (potassium oxalate/sodium fluoride) tube also accepted.
What is orange top tube used for?
RTS (Orange Top Tube)* Rapid Serum Tubes contain a proprietary thrombin-based medical clotting agent and a polymer gel for serum separation. They are used for serum determinations in chemistry.
Why are BD Vacutainer blood collection tubes safe?
BD Vacutainer plastic tubes offer a safe method of blood collection and reduce the potential for tube breakage and specimen spillage, thereby reducing the potential for exposure to bloodborne pathogens.
