EDTA K3 TUBE 2ML NV

About

EDTA K3 tubes are specialized blood collection tubes containing tripotassium ethylenediaminetetraacetic acid (EDTA) as an anticoagulant. The K3 variant refers to the potassium salt of EDTA, which functions by chelating calcium ions, thereby effectively preventing blood coagulation. These tubes are indispensable in clinical diagnostics for preserving the cellular components and morphology of blood, making them crucial for a wide array of hematological analyses. The 2mL fill volume is precisely calibrated to ensure the optimal blood-to-anticoagulant ratio, a critical factor for obtaining accurate and reliable test results. The 'NV' designation typically indicates a non-vacuum or specific manufacturing variant, though the core function remains consistent.

The primary role of EDTA K3 tubes is to maintain the integrity of blood cells for various laboratory tests, ensuring that parameters such as cell counts, differentials, and other cellular characteristics are reliably measured without interference from clotting. This preservation is vital for the accurate diagnosis and monitoring of conditions like anemia, infections, and leukemia, providing foundational data for patient management and treatment decisions. Proper handling and mixing immediately after blood collection are essential to ensure the anticoagulant is thoroughly dispersed throughout the sample, preventing microclot formation and preserving sample quality for subsequent analysis.

Uses

• Complete Blood Count (CBC) analysis.
• Blood film preparation for microscopic examination.
• Erythrocyte Sedimentation Rate (ESR) determination.
• Molecular diagnostic tests requiring whole blood.

Directions For Use

Collect blood sample directly into the tube, ensuring the correct fill volume. Gently invert the tube 8-10 times immediately after collection to ensure proper mixing of blood with the anticoagulant.

Benefits

• Effectively prevents blood coagulation.
• Preserves cellular morphology for accurate analysis.
• Ensures reliable hematological test results.
• Standardized for consistent diagnostic outcomes.
• Minimizes pre-analytical errors when handled correctly.
• Supports a wide range of hematology and molecular tests.

Side Effects

• Incorrect blood-to-anticoagulant ratio (if under/overfilled).
• Hemolysis (if vigorous mixing or improper collection technique).
• Clot formation (if inadequate mixing or delayed inversion).
• Contamination (if aseptic technique is not followed during collection).
• Inaccurate test results (due to pre-analytical errors).
• Cellular degradation (if stored improperly or for too long).
• Platelet clumping (can occur in some individuals).
• Fibrin strands (if mixing is insufficient).
• Sample rejection (if quality criteria not met).
• Need for re-collection (due to compromised sample).
• Patient discomfort (from venipuncture procedure).
• Risk of needlestick injury (to healthcare worker during collection).

Safety Measures

• Alcohol - Ensure venipuncture site is completely dry after alcohol swab application to prevent sample contamination or hemolysis.
• Pregnancy - No specific contraindications related to the tube itself for pregnant individuals. Standard blood collection protocols should be followed.
• Breastfeeding - No specific contraindications related to the tube itself for breastfeeding individuals. Standard blood collection protocols should be followed.
• Liver - No direct interaction with liver function. The tube is used for diagnostic purposes, and results may reflect liver conditions.
• Kidney - No direct interaction with kidney function. The tube is used for diagnostic purposes, and results may reflect kidney conditions.
• Lung - No direct interaction with lung function. The tube is used for diagnostic purposes.
