Red tubes clot blood for serum separation, and gold tubes contain SST for serum chemistry. Proper tube selection ensures accurate test results, crucial for diagnosis.
4.2 Phlebotomy Needles and Syringes
Phlebotomy needles are typically 20-25 gauge, designed for venipuncture. Safety needles feature protective shields to prevent needlestick injuries. Syringes are used for blood collection in challenging cases, such as pediatric or geriatric patients, ensuring precise control during the procedure. Proper needle selection and handling are critical for patient safety and accurate sampling.
4.3 Blood Transfer Devices and Their Functions
Blood transfer devices safely transfer blood from syringes or needles into vacuum tubes, preventing contamination and exposure. They feature safety mechanisms to activate needle protection, ensuring compliance with standard precautions. Proper use of these devices minimizes errors and maintains sample integrity for accurate laboratory testing.
Patient Preparation and Identification
Patient preparation involves reviewing medical history, ensuring proper identification, and selecting appropriate sites for blood collection. Clinical notes guide accurate specimen collection, ensuring safety and reliability.
5.1 Clinical Notes and Patient History
Clinical notes are vital for accurate blood collection, detailing patient history, diagnoses, and test results. Reviewing these notes helps phlebotomists identify potential complications and ensure safe, precise sampling. Thorough documentation prevents errors and ensures reliable lab results.
5.2 Patient Identification and Preparation Steps
Patient identification involves verifying identity using at least two identifiers, such as name and date of birth. Preparation includes explaining the procedure, ensuring fasting or hydration as required, and positioning the patient comfortably. Proper preparation ensures accurate test results and minimizes complications during blood collection.
5.3 Site Selection and Preparation for Blood Collection
Site selection involves assessing veins for accessibility and size. Preparation includes cleaning the area with antiseptic solution, positioning the arm appropriately, and ensuring the environment is clean. Proper site preparation minimizes complications and ensures a safe, effective blood collection process.
