Marble Top Serum Separator Blood Draw Sample

Provide an efficient means of serum sample preparation and help to improve laboratory workflow.

Marble top serum separator blood draw sample.

Draw 12 ml of whole blood for each 5 ml of serum or plasma needed. When plasma is required or when not using a serum gel separator tube follow these instructions. There are two kinds of sst tubes. These are known as yellow tops not gold.

Trademarked versions include covidien corvac tubes. 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. How these phlebotomy tubes are used follow the order of draw. They contain a special gel that separates blood cells from serum as well as particles to cause blood to clot.

The majority of samples require separation of plasma from cells within two hours of collection. Draw whole blood in an amount 2 times the required volume of serum so that a sufficient amount of serum can be obtained. Gently mix the blood collection tube by inverting 8 10 times immediately after collection. The 8 5 ml red top tube will yield approximately 3 5 ml serum after clotting and centrifuging.

5 0 ml 8 5 ml. Serum separator tubes also have red stoppers but with a yellow ring on top. 7 1 3 there are several tube types that may be used for serum collection depending on the. Draw a sufficient amount of blood with the indicated anticoagulant to yield the necessary plasma volume.

Centrifuge for at least 15 minutes at 2200 2500 rpm. These tubes are used to separate the blood cells from the serum. The tube must be inverted five times following blood collection. These tubes have a clot activator on the glass and a polymer gel as the separator.

Plastic tube 13 x 100 16 x 100. Sterile sst brand tube with inert clot activator determinations that require serum in chemistry or infectious disease testing. 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. 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. Marble top tubes are also referred to as tiger tops in some clinics. Gel separates serum from cells.

Sps tubes have a paler colour sometimes leading confusion. Tubes marked as best practice formulary meet demanding requirements of complex diagnostic instruments and current clinical guidelines.
