The plasma and serum can be extracted from the centrifugation of blood. Please enable it to take advantage of the complete set of features! 3 Only a few scientific studies have investigated the influence of . Notice how the gel starts out at the bottom of the tube before centrifugation. 3. Plain tubes with no anticoagulants have red stoppers and are used in the preparation of serum after clotting and centrifugation. The theory behind increased potassium after recentrifugation is that on initial centrifugation, the cells are separated from the serum by thixotropic gel. After proper centrifugation, serum can be left in contact with the gel barrier of SST tubes for up to 5 days with proper storage. This clotted blood is then centrifuged, yielding serum, which contains two types of protein: albumin and globulin. This is typically done by centrifuging the blood. 1.

This study investigated the effect of recentrifugation on the concentrations of glucose, sodium, potassium, chloride, BUN, creatinine, bicarbonate, calcium, phosphorus, and magnesium. A Verified Doctor answered. Serum provides the liquid portion of the blood without cells and clotting factors and, therefore, should contain proteins and other molecules that represent the whole body system.

We get them from time to time in red-top serum gel tubes, there just happens to be some unreacted fibrinogen and thrombin which is able to form a clear fibrin clot over time as the sample sits. Also, the original tubes are recentrifuged to ensure there is an adequate volume of serum or plasma for multiple repeating or different tests, and/or to run additional tests that are ordered hours after the original analysis was completed. Add 2 drops of the serum or plasma to be tested to a glass test tube. Blood after centrifuging in an SST tube. 3. The resulting components are: erythrocytes (red blood cells) at the bottom of the centrifuge tube. The SST contains gel that moves between to separate the blood cells and serum during the centrifugation process.
