Venous Blood Collection Tubes with K2 EDTA (dipotassium ethylenediaminetetraacetic acid) are primarily used for hematology tests. The K2 EDTA acts as an anticoagulant by binding calcium, preventing clotting and preserving the cellular components of the blood. These tubes are ideal for:

  1. Complete Blood Count (CBC): Analyzing red and white blood cells, hemoglobin, hematocrit, and platelets.
  2. Blood Smears: Evaluating the morphology of blood cells.
  3. Hemoglobin A1c: Assessing long-term glucose control in diabetes management.
  4. Blood Typing and Crossmatching: Preparing for blood transfusions.

The tubes ensure that the cellular integrity is maintained, enabling accurate and reliable results in hematological evaluations.

BD Vacutainer® Venous Blood Collection Tube K2 EDTA Additive is a type of vacutainer tube used for collecting venous blood samples. It has a lavender colored top and contains an anticoagulant called K2 EDTA (ethylene diamine tetraacetic acid) which helps prevent the blood from clotting. The tube has a volume of 4 mL and is 13 x 75 mm in size. It also has a Hemogard™ closure which is a safety feature that helps prevent accidental needlesticks and spills. The lavender top indicates that the tube is suitable for hematology tests, such as complete blood count (CBC), blood typing, and blood cell analysis. This type of tube is commonly used in clinical settings and laboratories for efficient and safe blood collection and analysis.

BD Vacutainer Venous Serum Blood Collection Tubes with K2 EDTA Additive are expertly designed to support accurate hematology testing by preventing coagulation. These tubes are essential for healthcare professionals who require precise blood sample analysis, making them a staple in laboratories and medical facilities.

Details and Features

  • Size and Capacity: Each tube measures 13 x 75 mm and has a 4 mL draw volume, optimized for hematology tests.
  • K2 EDTA Additive: Infused with dipotassium ethylenediaminetetraacetic acid (K2 EDTA), which serves as an anticoagulant to preserve blood cell integrity.
  • Lavender Closure: The color-coded lavender cap allows for easy identification of tubes intended for hematology use.
  • Packaging: Packaged in boxes of 100, these tubes are designed for efficient storage and convenience in high-usage environments.

Mechanism of Action

The K2 EDTA additive in the BD Vacutainer Venous Serum Blood Collection Tubes functions by chelating calcium ions in the blood. This action prevents clotting, ensuring that blood cells remain intact for precise hematological analysis, such as complete blood counts (CBC).

Directions for Use

  1. Preparation: Gather necessary equipment and ensure patient and site preparation according to protocol.
  2. Collection: Execute venipuncture, allowing the tube to fill to the 4 mL mark to maintain the correct blood-to-additive ratio.
  3. Mixing: Gently invert the tube 8-10 times immediately after collection to ensure thorough mixing with EDTA.
  4. Processing: Process the samples promptly as per lab guidelines to maintain sample integrity.

Warnings

  • Proper Fill: Underfilling or overfilling may lead to incorrect blood-to-additive ratios, compromising test accuracy.
  • Safety Precautions: Handle all sharps appropriately to avoid accidental needle sticks. Use in designated sharps disposal containers.
  • Storage Conditions: Keep tubes stored at temperatures between 4°C and 25°C, away from direct sunlight.
  • Single Use Only: Tubes are designed for one-time use. Do not attempt to reuse or re-sterilize.
  • Expiration Date: Always use tubes before the expiration date indicated on the package to ensure efficacy.

With BD Vacutainer Venous Serum Blood Collection Tubes with K2 EDTA Additive, you can achieve dependable, high-quality results across a variety of hematological tests, backed by the trusted coagulant properties of EDTA.

FAQs About Vacutainer Tubes
  • What Are Vacutainer Tubes?

    Vacutainer tubes are specialized, sterile blood collection tubes designed for safe, reliable, and contamination-free blood draws and specimen handling. These color-coded, single-use tubes ensure accurate diagnostic testing in hospitals, medical labs, clinics, and phlebotomy centers.

  • How are Vacutainer Tubes Used?

    Blood is drawn from the patient using a needle attached to a special holder. Tube is inserted into the holder; the vacuum draws the correct amount of blood into the tube. Tube is gently inverted (if required) to mix the blood with the additive. Tubes are labeled and sent to the laboratory for analysis.

  • Advantages of Vacutainer Tubes

    Safety: Minimizes exposure to blood. Efficiency: Allows multiple tubes to be drawn in a single venipuncture (“multiple draw” system). Accuracy: Delivers the correct volume for standardized testing.

  • Do Vacutainers Need to Be Sterile?

    Yes! Vacutainer tubes are sterile and individually sealed to prevent contamination and ensure accurate blood test results.

  • What is the Correct Order of Draw for a Vacutainer?

    Order of draw (to prevent cross-contamination): Blood culture bottles (yellow or SPS) Light blue (citrate) Red (serum, glass) Gold/Tiger top (SST, serum separator) Green (heparin) Lavender/Purple (EDTA) Gray (fluoride/oxalate)

  • What Do the Colors on Vacutainer Tubes Mean?

    Each color represents a different additive and test type: Yellow: Blood cultures, sterile Light Blue: Sodium citrate, coagulation studies (PT, aPTT) Red: No additive/Clot activator, chemistry/serology Gold/Tiger (SST): Serum separator (chemistry panels) Green: Heparin, plasma chemistry Lavender/Purple: EDTA, hematology (CBC) Gray: Sodium fluoride/potassium oxalate, glucose testing

  • Can Vacutainers Be Reused?

    No. Vacutainer tubes are single-use only to prevent infection, cross-contamination, and ensure accurate lab results.

  • How to Sterilize a Vacutainer?

    Do not attempt to sterilize or reuse. Always utilize new, sterile vacutainer tubes for each blood draw.

  • Where to Discard Vacutainer Tube?

    Dispose of used and expired vacutainers in a biohazard sharps container, as per OSHA and CDC safety protocols.

  • How Many Times Should an EDTA Tube Be Inverted?

    Gently invert the EDTA (lavender top) tube 8–10 times to mix the blood with the anticoagulant for accurate results.

  • What Are Common Phlebotomy Errors?

    Incorrect order of draw Insufficient mixing of tubes Underfilling or overfilling tubes Using expired tubes Hemolysis from poor technique Mislabeling specimens

  • What Color Lab Tube Do You Draw First?

    The blood culture (yellow/SPS) bottle is always drawn first to avoid contamination, followed by the light blue citrate tube.

  • What is a Grey Top Vacutainer Used For?

    Grey top tubes contain sodium fluoride and potassium oxalate and are used for glucose and lactate testing, as they prevent sugar breakdown in the sample.

  • What Color Should Blood Be When Drawn?

    Blood should appear dark red (venous) or bright red (arterial), based on the draw. Abnormal colors may indicate clinical problems.

  • Does a Vacutainer Expire?

    Yes, each vacutainer has an expiration date for sterility and additive effectiveness—never use expired tubes for specimen collection.

  • What Can Happen if Vacutainers Are Mixed Vigorously?

    Vigorous mixing causes hemolysis (rupture of red blood cells) and sample rejection. Always invert gently as instructed.

  • Are Vacutainers Single Use Only?

    Absolutely. Never reuse; always discard after a single blood draw to maintain patient safety and sample integrity.

  • What Temperature Should a Vacutainer Be Stored At?

    Store vacutainer tubes at room temperature (15°C–25°C / 59°F–77°F) in a dry, cool place away from direct sunlight and moisture.

  • How to Dispose of Expired Vacutainers?

    Expired vacutainers are disposed of in a biohazard sharps or chemical waste container per your lab’s safety policy.

  • How to Memorize Order of Draw Phlebotomy?

    Use the mnemonic: "Boys Love Ravishing Girls Like Dieters Love Greek Yogurt" (Blood culture, Light blue, Red, Gold, Light green, Dark green, Lavender, Gray, Yellow).

  • What Happens if You Underfill an EDTA Tube?

    Underfilling alters the blood-to-anticoagulant ratio, skewing hematology test results (like CBC). Always fill tubes to designated mark.

  • What is SST in Phlebotomy?

    SST (Serum Separator Tube) contains a gel that separates blood serum from cells after centrifugation. Used for chemistry panels, serology, and immunology tests.

  • What Labs Go in What Color Tubes?

    Blood culture (yellow): Microbiology Light blue: Coagulation (PT, aPTT) Red/Gold/Tiger: Chemistry, serology, immunology Green: Plasma chemistry (troponin, ammonia) Lavender/Purple: Hematology (CBC, HbA1c) Gray: Glucose testing
