Phlebotomy Made Simple: Core Skills and Patient Care

Explore the human circulatory system, including the heart, arteries, veins, and capillaries, and learn how blood transports oxygen, nutrients, and wastes to support safe phlebotomy and collection.

Explore the structure and function of blood, including red and white blood cells, platelets, and plasma, and learn how proper collection preserves test accuracy and prevents hemolysis.

Explore the roles of arteries, veins, and capillaries in circulation and phlebotomy, including how vessel type, location, and condition guide safe blood collection.

Identify common venipuncture sites and landmarks to locate veins reliably and minimize complications. Prioritize the median cubital vein at the antecubital fossa, using cephalic and basilic as alternatives.

Learn how age, hydration, body composition, and physiological factors affect vein size, visibility, and access from neonates to the elderly, and adapt venipuncture techniques for safe, accurate blood collection.

Understand blood collection systems and components, including evacuated tube systems, winged infusion sets, and syringes, covering vein access, additives, color coding, and safety for accurate samples and comfort.

Select appropriate needles and lancets based on patient characteristics and sample needs, considering gauge, length, and tip design. Activate safety mechanisms and use single-use devices to prevent injuries and contamination.

Explore blood collection tubes, their color-coded additives, and storage to prevent clotting, preserve serum or plasma, and ensure accurate results for hematology, coagulation, and chemistry tests.

Understand the scientific basis of the order of draw to prevent additive carryover and ensure accurate laboratory results across blood cultures, coagulation, chemistry, and hematology tests.

Tailor blood collection equipment to patient factors and test requirements, considering vein size, age, and conditions, selecting tubes and additives (EDTA, citrate, serum, plasma) to ensure safety and sample integrity.

Follow a consistent phlebotomy workflow from encounter to labeling and transport. Prepare by verifying orders, order of draw, identity, and obtaining consent.

Prioritize accurate patient identification and consent, document conversations and precollection factors like posture and hydration, and use interpreters when needed to prevent mislabeling and ensure reliable results.

Verify orders and patient identifiers, assemble supplies, and communicate expectations to ensure a safe, organized venipuncture, with proper site selection, draw technique, labeling, and documentation.

Master capillary blood collection for small-volume samples, using fingertip or heel with gentle technique, to ensure accurate results and handling when venipuncture is impractical for glucose, hemoglobin, and newborn screening.

Label specimens at the bedside with patient identifiers, date and time of collection, specimen type, and collector ID; verify barcodes match printed text to preserve chain of custody during transport.

Apply infection control and standard precautions in phlebotomy to prevent transmission of bloodborne pathogens, emphasizing hand hygiene, gloves and PPE, safe needle use, and proper disposal.

Prioritize patient safety in phlebotomy by following procedures, verifying identity, using safety devices, documenting incidents, and addressing near-misses to reduce errors.

Master pre-analytical variables that affect blood test results, including patient preparation, timing, collection technique, tube choice, mixing, transport, and storage. Document fasting, medications, and tourniquet time to support reliable interpretation.
