Specimen Collection Course

Lesson 1 • Overview of Specimen Types

Introduces blood, urine, tissue, and other specimen categories and their clinical purposes. Provides the classification framework used throughout the course.

Lesson 2 • Infection Control and Safety

Teaches standard precautions, personal protective equipment selection, and sharps safety. Establishes the safety baseline required before any hands-on collection.

Lesson 3 • Equipment Identification and Handling

Identifies needles, tubes, swabs, containers, and ancillary supplies by function. Correct equipment selection prevents pre-analytical errors addressed in later chapters.

Lesson 4 • Anatomy Relevant to Collection

Reviews vascular, urinary, and mucosal anatomy critical for accurate specimen access. Builds anatomical literacy needed for site selection in later chapters.

Lesson 1 • Patient Identification Protocols

Teaches two-identifier verification, wristband checks, and electronic order matching. Correct identification is the single most critical pre-collection safety step.

Lesson 2 • Reviewing the Test Order

Covers interpreting requisitions, confirming test codes, and flagging incomplete orders. Accurate order review prevents wrong-tube and wrong-test errors.

Lesson 3 • Pre-Collection Patient Assessment

Assesses fasting status, medication use, activity level, and contraindicated sites. These variables directly affect specimen quality and result interpretation.

Lesson 4 • Patient Communication and Consent

Develops skills for explaining procedures, addressing anxiety, and obtaining informed consent. Effective communication improves cooperation and reduces vasovagal events.

Lesson 1 • Syringe and Butterfly Collection

Addresses syringe draw technique and winged-needle use for fragile or difficult veins. These methods expand the collector's capability beyond standard evacuated draws.

Lesson 2 • Skin Antisepsis and Needle Insertion

Covers antiseptic selection, application technique, and needle insertion angle for clean venous access. Proper antisepsis prevents specimen contamination and patient infection.

Lesson 3 • Evacuated Tube System Collection

Demonstrates tube attachment, fill sequence, and mixing technique using the evacuated system. Tube order of draw prevents additive carryover that corrupts results.

Lesson 4 • Site Selection and Vein Assessment

Teaches palpation, visual inspection, and tourniquet use to identify optimal venepuncture sites. Correct site selection is the primary determinant of first-attempt success.

Lesson 1 • Point-of-Care Testing Integration

Connects capillary collection to bedside analysers for glucose, haemoglobin, and coagulation testing. Students apply collection skills directly to immediate result generation.

Lesson 2 • Fingerstick Procedure

Teaches site selection, lancet depth, and drop collection technique for adult fingerstick draws. Correct technique yields an adequate, uncontaminated drop for accurate testing.

Lesson 3 • Capillary Tube and Microcontainer Use

Demonstrates filling, sealing, and mixing of capillary tubes and microcontainers without air bubbles. Proper filling prevents clotting artefacts that invalidate results.

Lesson 4 • Neonatal Heelstick Procedure

Covers heel warming, safe puncture zones, and collection sequence for neonatal screening. Heelstick errors cause calcaneal injury, making precise technique essential.

Lesson 1 • Serous and Synovial Fluid Collection

Addresses pleural, peritoneal, pericardial, and synovial fluid collection support and handling. Proper tube allocation and mixing prevent clotting that limits analysis.

Lesson 2 • Amniotic and Seminal Fluid Procedures

Explains collection support, light protection, and temperature control for amniotic and seminal specimens. Specialised handling requirements differ significantly from routine body fluids.

Lesson 3 • Timed Urine Collection Procedures

Teaches patient instruction, container preparation, and volume measurement for 24-hour collections. Accurate timed collections require precise start and end protocols.

Lesson 4 • Cerebrospinal Fluid Handling

Covers CSF tube numbering, transport priority, and stability requirements after physician collection. Correct handling preserves cell counts and prevents misdiagnosis.

Lesson 1 • Genital and Urinary Tract Cultures

Covers urethral, cervical, and vaginal swab technique and transport for sexually transmitted infection testing. Proper site access and media selection preserve fastidious organisms.

Lesson 2 • Wound and Tissue Swab Collection

Covers wound bed sampling, swab rotation technique, and transport media selection for wound cultures. Superficial swabbing yields colonisers, not pathogens, making depth critical.

Lesson 3 • Blood Culture Collection

Teaches skin antisepsis, bottle inoculation sequence, and volume requirements for blood cultures. Contamination prevention is paramount because false positives drive unnecessary treatment.

Lesson 4 • Stool and Enteric Specimen Collection

Teaches stool collection containers, preservative selection, and rectal swab technique for enteric pathogens. Correct preservative prevents organism death during transport.

Lesson 1 • Haemolysis, Lipemia, and Icterus

Explains causes, visual detection, and analytical impact of haemolysis, lipemia, and icterus. These interferences affect dozens of common assays and trigger specimen rejection.

Lesson 2 • Quality Indicators and Metrics

Introduces collection quality indicators such as haemolysis rate, recollection rate, and turnaround time. Tracking metrics enables continuous improvement of collection practice.

Lesson 3 • Specimen Stability and Transport

Covers time-to-centrifugation, temperature requirements, and light sensitivity for common analytes. Stability knowledge prevents result drift during transport and storage.

Lesson 4 • Sources of Pre-Analytical Error

Catalogues patient, collection, and transport variables that introduce error before analysis begins. Recognising error sources is the prerequisite for systematic prevention.

Lesson 1 • Paediatric Collection Adaptations

Addresses age-appropriate communication, restraint, site selection, and volume limits for children. Paediatric collections require modified technique to ensure safety and specimen adequacy.

Lesson 2 • Bariatric and Lymphedema Considerations

Covers site selection, equipment sizing, and positioning for obese patients and those with lymphedema. Lymphedema-affected limbs are contraindicated, requiring alternative site identification.

Lesson 3 • Oncology and Immunocompromised Patients

Addresses port access support, neutropenic precautions, and thrombocytopenia management during collection. These patients face heightened infection and bleeding risk requiring strict protocol adherence.

Lesson 4 • Difficult Venous Access Strategies

Teaches escalating strategies for patients with poor venous access, including alternative sites and devices. Systematic escalation reduces patient discomfort and unnecessary attempts.
