FAQs About Serum Blood Collection Tubes
  • What are Serum Blood Collection Tubes used for?

    Serum blood collection tubes are specialized containers used in clinical laboratories and healthcare settings to collect, transport, and process blood samples specifically for tests that require serum.

  • What Is Serum?

    Serum is the clear, straw-colored liquid portion of the blood that remains after clotting has occurred and the blood cells and clotting factors have been removed. It contains water, electrolytes, hormones, antibodies, antigens, and other proteins—but no clotting factors.

  • What Are Serum Blood Collection Tubes?

    These tubes are commonly red-top (no additives) or yellow-top/gold-top (contain a gel separator and sometimes a clot activator). Some tubes have a clot activator to speed up the clotting process; others may have a gel separator that forms a barrier between serum and blood cells after centrifugation.

  • How They Are Used

    Blood is drawn into the tube (often from a vein in the arm). The blood is allowed to clot (takes 15–30 minutes). The tube is centrifuged to separate the serum from the cells and clot. Serum is carefully collected for laboratory analysis.

  • Which Color Tube Is Used for Serum?

    Red Cap/Red-Top Tubes: The classic choice for serum collection. Contains no additives. Gold Top (Yellow/Gold with Gel Separator, SST): Contains a serum separator gel for enhanced serum yield and purity. Plain Tubes: Used for routine serum testing in clinical chemistry. Marble-Top (Tiger Top) Tubes: Sometimes used, featuring a gel separator

  • What Tube to Obtain a Serum Sample?

    To obtain a serum sample, use a red, gold (SST), or plain-top tube. Let the blood clot, then centrifuge to separate the serum for testing.

  • Which Vial Is Used for Serum?

    A plain (red) or gold-top (SST) serum blood collection tube is used to collect serum from a blood sample.

  • Which Tube Color Is Most Commonly Used for Serum Testing?

    The red-top or gold-top (SST) tubes are most commonly used for serum testing in clinical and diagnostic laboratories.

  • Which Tube Would You Use to Draw a Sample for Serum?

    Always use a serum blood collection tube: red-cap (plain), gold-top (SST), or marble-top (tiger).

  • Is a Green Tube Plasma or Serum?

    A green-top tube contains heparin and is used for plasma, NOT serum.

  • Is EDTA Serum or Plasma?

    The EDTA tube (lavender/purple-top) is used for plasma, not serum. EDTA prevents clotting, resulting in plasma after centrifugation.

  • What Is a Plain Serum Tube Used For?

    A plain serum tube (red-top) is used for collecting blood, letting it clot, and obtaining serum for: Blood chemistry analysis Immunology/serology Drug monitoring Hormone assays

  • How Do You Collect Blood Serum?

    Draw blood into a red-top, gold-top SST, or plain tube. Allow blood to clot (usually 10–30 minutes). Centrifuge to separate serum from the clot. Collect serum for laboratory testing.

  • Which Vacutainer Tube Is Used to Collect Serum?

    Use a red-top vacutainer, gold-top SST vacutainer, or plain vacutainer tube for serum collection.

  • What Are the Three Main Veins to Draw Blood?

    Median cubital vein (most common) Cephalic vein Basilic vein

  • Why Choose Our Serum Blood Collection Tubes?

    Sterile, pyrogen-free, leak-proof design Fast serum separation with or without gel No hemolysis, minimal sample rejection Universal compatibility with all phlebotomy and automated analyzers
