7 1 3 there are several tube types that may be used for serum collection depending on the.
Marble top serum separator blood draw sample.
The 8 5 ml red top tube will yield approximately 3 5 ml serum after clotting and centrifuging.
It contains a gel that effectively separates the cells from the serum when run through centrifugation.
Contain spray coated silica and a polymer gel for serum separation.
Hemogardtm gold top conventional red gray marble.
Collect in an appropriate collection tube.
7 1 2 the most commonly used tube types for serum collection are non red top tube with no anticoagulant or sst serum separator tube with clot activator and polymer separation gel for serum separation.
Draw 12 ml of whole blood for each 5 ml of serum or plasma needed.
The majority of samples require separation of plasma from cells within two hours of collection.
Gently mix the blood collection tube by inverting 8 10 times immediately after collection.
Sterile sst brand tube with inert clot activator determinations that require serum in chemistry or infectious disease testing.
Trademarked versions include covidien corvac tubes.
They contain a special gel that separates blood cells from serum as well as particles to cause blood to clot.
There are two kinds of sst tubes.
These tubes have a clot activator on the glass and a polymer gel as the separator.
Draw a sufficient amount of blood with the indicated anticoagulant to yield the necessary plasma volume.
When plasma is required or when not using a serum gel separator tube follow these instructions.
Marble top tubes are also referred to as tiger tops in some clinics.
One tube has a gold stopper and the other has a red gray marble stopper.
Plastic tube 13 x 100 16 x 100.
The tube must be inverted five times following blood collection.
Centrifuge for at least 15 minutes at 2200 2500 rpm.
These are known as yellow tops not gold.
Tubes marked as best practice formulary meet demanding requirements of complex diagnostic instruments and current clinical guidelines.
These tubes are used to separate the blood cells from the serum.
How these phlebotomy tubes are used follow the order of draw.
5 0 ml 8 5 ml.
These include red top collection tubes with serum separator grey top tubes with a fluoride glycolysis inhibitor and heparin containing green top tubes which prevent clot formation.
Draw whole blood in an amount 2 times the required volume of serum so that a sufficient amount of serum can be obtained.
Sps tubes have a paler colour sometimes leading confusion.
Provide an efficient means of serum sample preparation and help to improve laboratory workflow.
