Types of Blood Collection Tubes and How to Distinguish Multi-colored Blood Collection Tubes
Red Blood Collection Tube – Regular/Rapid Serum Tube
The red blood collection tube, or a biochemical tube, does not contain anticoagulants. The inner wall of the box is uniformly coated with an anti-coagulant to prevent clotting. It is primarily used for blood biochemistry tests. There are two types: regular and rapid serum tubes, distinguished by labeling indicating the presence of clot activator or by using red and orange caps. The clot activator accelerates blood clotting, making it suitable for obtaining quicker results.
Sample Type: Serum
Applications: Bacterial testing, tumor screening, gonadal hormone assays, routine immunological tests, comprehensive immunological assays, rheumatoid antibody tests, diabetic nephropathy screening, complete blood counts, prostaglandin assays, HBV-DNA testing, ferritin testing, cold agglutination tests, calcitonin testing, chlamydia antibody tests, gastrin testing, ANCA tests, cytomegalovirus antibody tests, human epididymal secretory protein testing, serum protein electrophoresis, RA panel tests, TB-AD tuberculosis antibody tests, and more.
Green Blood Collection Tube – Heparin Anticoagulant Tube
The green blood collection tube contains heparin, a substance with direct anticoagulant properties that extend the coagulation time of the specimen. Excessive heparin can cause white blood cell aggregation, rendering it unsuitable for white blood cell counts. Moreover, it may lead to a pale blue background in blood smears after staining, making it unsuitable for white blood cell classification.
Sample Types: Whole blood, plasma
Applications: Red blood cell fragility tests, blood gas analysis, hematocrit tests, erythrocyte sedimentation rate (ESR) tests, and routine biochemical assays.
Light Green Blood Collection Tube – Plasma Separation Tube
The light green blood collection tube contains lithium heparin or sodium heparin along with a gel separator. Heparin is a polysaccharide with sulfate groups, carrying a strong negative charge. It effectively inhibits the formation of thrombin, inactivating serine proteases. It also prevents platelet aggregation and offers various anticoagulant effects. Typically, 15 IU of heparin anticoagulates 1 ml of blood. Heparin tubes are commonly used for emergency biochemical and hemorheological (blood flow) tests.
Sample Type: Plasma
Applications: Tests for TNT, environmental mycotoxins, B27 antigen, blood ammonia levels, and B-type natriuretic peptide (BNP).
Purple Blood Collection Tube – EDTA Anticoagulant Tube
The purple blood collection tube contains EDTA (Ethylenediaminetetraacetic acid) anticoagulant. Compared to other anticoagulants, EDTA has a minimal impact on blood cell aggregation and morphology in routine blood tests. Therefore, EDTA salts (e.g., K2, K3, or Na2) are commonly used as anticoagulants. EDTA salts can chelate with calcium ions in the blood, preventing blood clotting.
Sample Type: Whole Blood, Plasma
Applications:
2ml Tube: Hematology tests, reticulocyte count, glycosylated hemoglobin (HbA1c), TC blood group, B-type natriuretic peptide (BNP).
5ml Tube: Pituitary function tests, parathyroid hormone, renin, adrenal function, adrenocorticotropic hormone (ATCH) + cortisol (COR), cortisol, blood typing + D antigen (crossmatch).
Not suitable for coagulation tests, platelet function assays, calcium, potassium, sodium, iron, alkaline phosphatase, creatine kinase, and lysyl aminopeptidase measurements, as well as PCR assays.
Yellow Blood Collection Tube – Inert Separation Gel with Clot Activator Tube
The yellow blood collection tube contains an inert separation gel and a clot activator. The tube’s inner wall is coated with a clot activator, which accelerates blood coagulation, eliminating the need for a 37℃ water bath and reducing testing time. The separation gel exhibits excellent affinity with PET tubes, serving as an effective barrier.
Sample Type: Serum
Applications:
3ml Tube: Biochemical tests, digoxin concentration, myocardial enzymes, amylase, thyroid function tests (TFT), free thyroxine (FT4), total thyroxine (TT4), thyroid antibody tests, thyroid receptor antibody tests.
5ml Tube: C-reactive protein (CRP) immunoassays (suitable for both serum and plasma), high-sensitivity C-reactive protein (hs-CRP).
Light Blue Blood Collection Tube – Sodium Citrate Tube
The light blue blood collection tube contains 3.2% or 3.8% sodium citrate. When collecting blood, ensure an adequate blood volume to guarantee accurate test results. After blood collection, immediately invert the tube 5-8 times to mix thoroughly. The anticoagulant-to-blood ratio is 1:9.
Sample Type: Whole blood, plasma
Applications:
Used for fibrinolysis system tests, including prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin time (TT), and fibrinogen testing.
Black Blood Collection Tube – Sodium Citrate ESR Tube
The black blood collection tube contains 3.2% (0.109mol/L) to 3.8% sodium citrate (citric acid sodium salt). The anticoagulant in this tube has a blood-to-anticoagulant volume ratio of 1:4. When the anticoagulant ratio is too high, it can dilute the blood, leading to a faster erythrocyte sedimentation rate (ESR). Heparin anticoagulant can alter the electrical charge of red blood cells, making it unsuitable for ESR testing.
Sample Type: Whole blood
Applications: Used for ESR (erythrocyte sedimentation rate) testing.
Gray Blood Collection Tube – Sodium Fluoride/Potassium Oxalate Glucose Tube
The gray blood collection tube contains additives such as sodium fluoride + potassium oxalate/sodium fluoride + sodium heparin. Sodium fluoride is a weak anticoagulant that effectively prevents glucose degradation. A mixture of sodium fluoride + potassium oxalate/sodium fluoride + sodium heparin at 4mg can prevent blood from clotting and inhibit sugar decomposition in 1ml of blood for up to 23 days. When using this tube, please ensure slow and thorough inversion for proper mixing.
Sample Type: Whole blood
Applications: Primarily used for glucose testing. Not suitable for urease method urea testing, alkaline phosphatase, and amylase testing.
Apart from the commonly used blood collection tubes mentioned above, there are specialized tubes for specific tests, such as lead element detection tubes, whole blood RNA tubes, plasma protein preservation tubes, ACD tubes, and more. The suitability of these tubes for specific tests depends on the additives present in the tubes and should be considered accordingly.
Distinguishing Between EDTA, Sodium Citrate, Oxalate, and Heparin Anticoagulants
EDTA, sodium citrate, and oxalate all work by binding to calcium ions, the fourth coagulation factor in the blood, preventing the coagulation cascade from occurring and thus exhibiting anticoagulant effects. Since they consume calcium ions, they are not suitable for electrolyte testing in blood.
Heparin, being a natural anticoagulant, does not deplete calcium ions and can be used for electrolyte testing. However, heparin can cause white blood cell aggregation, affecting white blood cell counts and making it unsuitable for routine blood tests.
Sodium fluoride can inhibit the breakdown of blood glucose, making it recommended for blood glucose testing.
Why Are Blood Collection Tubes Color-Coded?
Blood collection tubes come in a variety of colors, and each color represents a specific tube type and its intended use. This color-coding system is essential for healthcare professionals to ensure accurate and reliable test results.
Identification: The color coding simplifies the identification of the tube type and its purpose, reducing the risk of errors during sample collection and processing.
Anticoagulants: Different tubes contain various anticoagulants or clot activators. The color helps in distinguishing tubes with additives like EDTA (purple), heparin (green), sodium citrate (light blue), or no additives (red).
Preventing Contamination: Color-coding ensures that the right tubes are used for specific tests, preventing contamination of samples and ensuring the reliability of results.
Efficiency: Healthcare professionals can quickly select the appropriate tube, streamlining the blood collection process and saving valuable time.
Standardization: The use of standardized color coding enhances laboratory efficiency and minimizes the chances of sample mix-ups.
