Virginia’s CTE Resource Center

Demonstrate blood collection, handling, and processing for venipuncture procedures.

Definition

Demonstration should include the following:
  • A. Primary Collections
    • Demonstrate proper insertion and removal techniques for venipuncture.
    • Perform the capillary collection method based on the patient's age and condition.
    • Ensure the patient's safety throughout the collection process.
    • Perform venipuncture steps in the correct order (e.g., evacuated tube system, syringe, winged collection set).
    • Perform capillary (dermal) puncture steps in correct order.
    • Recognize common complications from primary collection (e.g., lack of blood flow, hematoma, petechiae, nerve injury).
    • Identify problematic patients and the importance of the order of the draw. Monitor signs and symptoms throughout collection (e.g., syncope, diaphoresis, nausea, seizure).
    • Follow the order of the draw a) venipuncture b) capillary collection.
    • Ensure that tube additives are appropriate for testing requirements.
    • Assemble the equipment needed for primary blood collections.
    • Invert evacuated tubes with additives after collection.
    • Verify the quality of equipment (e.g., sterility, expiration date, manufacturer’s defects).
  • B. Special Collections
    • Prepare peripheral blood smears.
    • Perform blood culture collections.
    • Assist other healthcare professionals with blood culture collections.
    • Collect blood samples for inborn errors of metabolism (e.g., PKU, galactosemia).
    • Perform phlebotomy for blood donations.
    • Calculate volume requirements to avoid causing iatrogenic anemia.
  • C. Processing
    • Label all specimens.
    • Perform quality control for Clinical Laboratory Improvements Amendments (CLIA)-waived procedures.
    • Transport specimens based on handling requirements (e.g., temperature, light, time).
    • Explain non-blood specimen collection procedures to patients (e.g., stool, urine, semen, sputum).
    • Handle patient-collected, non-blood specimens.
    • Avoid pre-analytical errors when collecting blood specimens (e.g., QNS, hemolysis).
    • Adhere to chain of custody guidelines when required (e.g., forensic studies, blood alcohol, drug screen).
    • Prepare samples for transportation to a reference (i.e., outside) laboratory.
    • Coordinate communication between non-laboratory personnel for processing and collection.
    • Use technology to input and retrieve specimen data.
    • Report critical values to point-of-care testing (finger stick, blood glucose.
    • Distribute laboratory results to ordering providers.

Process/Skill Questions

  • Where is the best place to perform a finger stick for a capillary collection?
  • How long may the tourniquet be left on the patient?
  • Why is there a time limit?
  • What is the rationale for inverting the vacutainers after blood draws?
