Red stopper tube- For information on the sampling process, refer to the order of collection with multiple tube collections and the tests found elsewhere in this laboratory testing guide to the specifications for samples Serum separator tubes, also known as serum separator tubes or SSTs, are used in clinical chemistry testing used that require blood serum. If frozen serum is required, place the plastic transport tubes (prepared above) immediately in the freezer compartment of the refrigerator. This tube must be completely filled; the ratio of blood to anticoagulant is crucial for valid coagulation results.
These tubes should be used with caution when measuring drug or hormone levels, as the drug or hormone may diffuse from the serum into the gel, which may result in a decrease in measured levels.
Which tubes are considered SST?
A tiny rubber cover automatically closes when the vacuum tube is removed from its holder, preventing leakage and blood loss when changing tubes. When more than one blood sample is required, multiple sample needles and vacuum tubes make blood collection easier and more efficient. If multiple samples are required, remove the first collection tube from its holder as soon as blood flow is interrupted, turn the first tube upside down to prevent clotting, and gently insert the second tube into the holder. Serum separator tubes, also known as serum separator tubes or SSTs, are used in clinical chemistry tests that require blood serum.
What is the red blood probe for?
Before collecting the patient, please get in touch with the laboratory to obtain the correct tubes for metal analysis or other tests as specified in the individual test lists.
What is the difference between an SST and a red stopper tube?
These tubes should be used with caution when measuring drug or hormone levels, as the drug or hormone may diffuse from the serum into the gel, which may result in a decrease in measured levels. The stopper of SPS tubes (sodium polymethyl sulfonate) is pale yellow in color, which sometimes causes confusion. These are referred to as yellow tips and not gold. SSTs are sometimes referred to as marble-topped tubes, tiger tops, or gold tubes and refer to the plugs that are either gold, red with a gold ring at the top, or marbled red and gray. However, since patients have a variety of arm positions and contamination of the needle that punctures the stopper cannot always be prevented, an arrangement is required.
