Serum Blood Collection Tubes are vacuum blood collection tubes that do not contain anticoagulants, preservatives, or separating materials. Used to collect serum for specific laboratory tests and isolate serum after phlebotomy for clinical chemistry, immunology, and therapeutic drug testing. Coagulants work to speed up blood clotting, and the use of coagulation vessels reduces turnaround time. The tube is a disposable negative pressure vacuum glass tube or a disposable negative pressure vacuum plastic tube that can realize quantitative blood collection and needs to be used with a venous Blood Collection Needle.
Its principle is a negative-pressure vacuum blood collection tube, which uses its negative pressure to automatically and quantitatively collect venous blood samples. Human venous blood is drawn into the blood sample container through the Blood collection needle under the negative pressure of the vacuum blood collection tube. One venipuncture can collect multiple tubes without leakage.
The volume of the lumen connected to the blood collection needle is small, the influence on the blood collection volume is negligible, and the probability of backflow is relatively small. If the lumen volume of the butterfly blood collection needle is large, it will consume part of the vacuum of the blood collection tube, thereby reducing the blood collection volume.

Blood Collection Tube Classifications
Red blood collection tube, normal or fast serum tube
The labeling of ordinary serum tubes and fast serum tubes involves a distinction between those marked with or without a procoagulant, utilizing red and orange colors to highlight the differences. The facilitation of blood clotting is attributed to the presence of a procoagulant. The use of a procoagulant achieves the acceleration of blood clotting.
Applicable sample type: Serum
Uses: PCT, mycoplasma antibodies, gastrin ANCA, blood cytomegalovirus antibody, human epididymal epithelial secretory protein, serum protein electrophoresis, RA five, TB-AD tuberculosis antibody.
Light green blood collection tube Plasma separation tube
Heparin possesses a mucopolysaccharide nature with a pronounced negative charge on its sulfate group. It forms a composition with sodium or lithium heparin and a gelling agent. This characteristic renders the antithrombin three-inactivating serine protease more potent.
Applicable sample type: Plasma
Uses: B27, blood ammonia, BNP (B-type natriuretic peptide)
A light blue blood collection tube Trace element tube
Includes procoagulant (plastic tube, serum) and non-procoagulant (glass tube, serum) additives, as well as sodium heparin, EDTA Na2, and EDTA K2.
Uses: trace elements, toxicology and nutritional chemistry tests.
Green blood collection tube Heparin anticoagulation tube
The blood collection tube has heparin added to it. Heparin directly exerts the antithrombin effect, resulting in the prolongation of the clotting time of the specimen.
Applicable sample types: Whole blood, plasma
Use: Sedimentation, general biochemical determination, red blood cell fragility test, blood gas analysis, and red blood cell pressure test.
Purple blood collection tube EDTA anticoagulant tube
EDTA anticoagulant, the routine blood test employs this particular anticoagulant. other anticoagulants, EDTA Tubes has minimal impact on both blood coagulation and cell morphology
Grey blood collection tube Sodium oxalate/sodium fluoride blood glucose test tube
Sodium fluoride, potassium oxalate, sodium fluoride, and sodium heparin are the ingredients in the tube. One beneficial consequence of sodium fluoride, a mild anticoagulant, is that it can stop the breakdown of blood glucose.
To create a solution that prevents blood coagulation and inhibits sugar decomposition for 23 days, combine 4mg of the sodium fluoride + potassium oxalate/sodium fluoride + sodium heparin mixture in 1 ml.
Sample type: whole blood, plasma
Uses: 2ml: blood routine, reticulocytes, glycated hemoglobin
A light blue blood collection tube sodium citrate (sodium citrate) blood collection tube
Containing 3.2% or 3.8% sodium citrate (sodium citrate), please take care to collect enough blood to ensure the accuracy of test results. Please invert and mix 5-8 times immediately after blood collection.
Applicable specimen type: Whole blood, plasma
Use: Prothrombin time, prothrombin time, activated partial thromboplastin time, and fibrinogen are examples of fibrinolytic systems.
Golden yellow blood collection tube Inert separation pro-coagulation tube
To speed up blood coagulation and reduce test time, apply a coagulant to the tube wall and refrain from using a 37℃ water bath. Separation gel and PET tube have a good affinity and play a role in isolation.
Applicable specimen type: Serum
Use 3ml: Biochemical items, digoxin concentration, cardiac enzymes, amylase, thyroid function, full thyroid function, free thyroid function.
5ml: C-reactive protein (CRP immunity, red and yellow), high-sensitivity C-reactive protein (hs-CRP)
A black blood collection tube Sodium citrate blood sedimentation test tube
Contains 3.2% (0.109 mol/L)-3.8% sodium citrate (sodium citrate) with a volume ratio of anticoagulant to blood of 1:4.
Heparin, as an anticoagulant, can alter the potential of red blood cells.
Applicable sample type: Whole blood
Use: Blood sedimentation
Faqs
What color tube is used for serum?
The distinctive red color indicates the absence of anticoagulants or clot activators, allowing the blood to clot naturally. This clotting process separates the serum from the blood cells, facilitating accurate diagnostic testing.
What are serum tubes for blood collection?
Specialized containers, recognized as red-top tubes, designed for collecting blood samples for diagnostic testing, play a crucial role in maintaining the integrity of serum—the liquid component of blood acquired after coagulation.
What is the name of the serum tube?
A red-top tube is the designation for a tube specifically designed for serum collection. The nomenclature originates from the tube’s distinct red color, which signifies its purpose of allowing blood to clot and separating the serum for analysis.
What container is used for serum collection?
The container used for serum collection is the red-top tube. It is a standard in laboratories and healthcare settings for obtaining blood samples for various diagnostic tests. The absence of additives in the tube ensures that the serum remains in its natural state, providing accurate results during laboratory analysis.
