To obtain serum for a blood test you need to use a tube without any anticoagulant. You use a needle and the tube to draw blood from a persons veins.
The gel in the SST (serum separator tube) tube separates serum from the clot after centrifugation. This helps to obtain clear serum for diagnostic testing by preventing cells and clotting factors from interfering with the analysis.
No, heparin tubes are not typically used for prostate-specific antigen (PSA) testing. The recommended tube for PSA testing is a serum separator tube (SST) or a plain red-top tube to obtain a serum sample for analysis.
What are you testing for in the serum?
A gold or red/gray tiger top tube (serum separator tube) is typically used for GGT (gamma-glutamyl transferase) testing. This tube contains a clot activator and gel separator to obtain serum for testing.
The color tubes used for serum iron tests are typically red or gold-topped vacuum tubes. These tubes contain a clot activator and gel separator to obtain serum for testing. Serum iron levels are measured to assess iron deficiency or iron overload in the body.
Serum is typically viable for alcohol testing for up to 3-5 days when stored in a proper container at the recommended temperature. However, it is always best to consult with a medical professional or testing facility for specific guidance on the viability of serum samples for alcohol testing.
A gold or red-top tube is typically used for hyperlipidemia testing, as these tubes contain a gel separator to separate serum from cells. The gel separator helps to obtain a clear serum sample for lipid analysis.
A red or gold-top tube is typically used for testing herpes virus antibodies. These tubes usually contain a clot activator and gel separator to obtain serum for testing.
A red-top tube (serum separator tube) would typically be used to draw blood for a vancomycin peak level test. This tube contains a clot activator and gel separator to obtain serum for testing.
The gel at the bottom of SST tubes is a gel separator made of a material like silicone. Its purpose is to separate the serum (liquid portion of blood) from the clot (solid portion of blood) after the blood has been centrifuged. This makes it easier to obtain a clear serum sample for testing.

There are many places where one can obtain diabetic testing. One can obtain diabetic testing at popular medical facilities such as the Mayo Clinic and Sutter Health.
