2. Lavender Top Tubes: These tubes contain the Anticoagulant EDTA and are used for hematology tests.
3. Green Top Tubes: These tubes contain the Anticoagulant Heparin and are used for chemistry tests.
4. Gray Top Tubes: These tubes contain Sodium Fluoride and Potassium Oxalate and are used for glucose testing.
5. Blue Top Tubes: These tubes contain citrate and are used for coagulation studies.

The Blood Collection Process Using Test Tubes

The blood collection process using test tubes typically involves the following steps:

1. Verify the patient's identity and obtain the necessary information.

2. Label each test tube with the patient's full name, date of birth, date and time of collection, and any other required information.
3. Handle the test tubes carefully to prevent any leakage or contamination of the blood specimen.
4. Store the test tubes in the appropriate conditions to maintain the integrity of the blood specimen.
5. Follow the Proper Disposal procedures for used test tubes to prevent any potential hazards.

Conclusion

Test tubes are an indispensable tool in the blood collection process during phlebotomy. They play a crucial role in collecting, storing, and transporting blood specimens for various laboratory tests. Proper handling and labeling of test tubes are essential to ensure accurate Test Results and patient safety. Phlebotomists must be well-versed in the different types of test tubes used and follow the appropriate procedures to provide quality care to their patients.
