5 0 ml 8 5 ml.
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.
Collect in an appropriate collection tube.
Serum separator tubes also have red stoppers but with a yellow ring on top.
These tubes are used to separate the blood cells from the serum.
Tubes marked as best practice formulary meet demanding requirements of complex diagnostic instruments and current clinical guidelines.
Sps tubes have a paler colour sometimes leading confusion.
Provide an efficient means of serum sample preparation and help to improve laboratory workflow.
Trademarked versions include covidien corvac tubes.
When plasma is required or when not using a serum gel separator tube follow these instructions.
The majority of samples require separation of plasma from cells within two hours of collection.
How these phlebotomy tubes are used follow the order of draw.
The tube must be inverted five times following blood collection.
Contain spray coated silica and a polymer gel for serum separation.
Centrifuge for at least 15 minutes at 2200 2500 rpm.
Plastic tube 13 x 100 16 x 100.
These tubes have a clot activator on the glass and a polymer gel as the separator.
Hemogardtm gold top conventional red gray marble.
As part of a quality assurance project we investigated whether glucose levels differed in the three tube types from each of 18 volunteers on a prolonged standing of 4 hours.
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.
Marble top tubes are also referred to as tiger tops in some clinics.
They contain a special gel that separates blood cells from serum as well as particles to cause blood to clot.
One tube has a gold stopper and the other has a red gray marble stopper.
Sterile sst brand tube with inert clot activator determinations that require serum in chemistry or infectious disease testing.
Draw whole blood in an amount 2 times the required volume of serum so that a sufficient amount of serum can be obtained.
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.
Gel separates serum from cells.
There are two kinds of sst tubes.
These are known as yellow tops not gold.
Draw a sufficient amount of blood with the indicated anticoagulant to yield the necessary plasma volume.
Gently mix the blood collection tube by inverting 8 10 times immediately after collection.
