Lesson 1Sample Tube Pickin', Additives (EDTA fi CBC, Glycolytic Inhibitor fi Glucose) an' WhyDetails right tube types an' additives fi glucose an' CBC, explainin' EDTA role in keepin' cell shape an' glycolytic inhibitors in stabilizin' glucose, plus color code, fill volume, an' common pick errors.
EDTA tube selection for CBC testingFluoride oxalate and other glycolytic inhibitorsTube color codes and manufacturer variationsRequired fill volume and anticoagulant ratioAdditive mechanisms and cellular effectsConsequences of wrong tube selectionLesson 2Storage, Transport Conditions, an' Time Limits fi Glucose an' CBC SamplesCovers temperature, light, an' time limits fi glucose an' CBC specimens, includin' cool packs, pneumatic tubes, an' max holdin' times, fi keep analyte stable an' stop preanalytical breakdown or clottin'.
Room temperature vs refrigerated storageUse of ice slurries for glucose stabilityTransport timing for CBC samplesPneumatic tube and courier considerationsMaximum pre-analytical holding timesMonitoring and documenting transport conditionsLesson 3Step-by-Step Venipuncture Technique wid Focus pon Minimisin' HemolysisGi' structured venipuncture steps focus on minimisin' hemolysis, coverin' equipment prep, vein entry angle, tourniquet timin', tube handlin', an' ways fi avoid frothin', too much suction, or repeated probin'.
Pre-assembly and inspection of equipmentOptimal skin antisepsis and drying timeNeedle angle, depth, and vein anchoringTourniquet release timing and impactGentle tube filling and avoiding frothingManaging difficult draws without traumaLesson 4Immediate After-Draw Handlin': Inversion, Mixin', Clottin' Times, an' Aliquotin'Covers immediate handlin' steps after venipuncture, includin' right inversion counts, mixin' technique, clottin' times, centrifugation readiness, an' aliquotin', fi keep sample whole fi glucose an' CBC analysis.
Inversion counts for EDTA and fluoride tubesProper mixing technique to avoid hemolysisRequired clotting times for serum tubesTiming of centrifugation for stabilityAliquot labeling and secondary containersHandling delays and documentationLesson 5Waste Disposal, Sharps Management, an' After-Procedure Patient Care an' Watchin'Describe safe disposal of sharps an' biohazard waste, handlin' accidental exposures, an' key after-procedure patient care, includin' site check, instructions, an' watchin' fi bleedin', hematoma, or vasovagal reactions.

Indications and technique for hand hygieneGloves, gowns, masks, and eye protectionRisk-based PPE selection for phlebotomyRespiratory hygiene in collection areasEnvironmental cleaning of draw stationsPolicies for immunocompromised patientsLesson 7Vein Pickin', Tourniquet Use, an' Order of Draw PrinciplesExplain criteria fi choosin' right veins, safe tourniquet apply, an' CLSI order of draw, stressin' stoppin' additive carryover an' hemoconcentration weh could change glucose or CBC results.
Preferred and alternative venipuncture sitesAvoiding compromised or painful veinsTourniquet placement and time limitsEffects of prolonged stasis on resultsCLSI order of draw sequence detailsOrder of draw for multiple glucose tubesLesson 8Labellin' Needs an' Key Documentation FieldsExplain must-have labellin' parts an' documentation fi glucose an' CBC samples, includin' patient IDs, collection details, test requests, an' legal needs, fi ensure traceability, cut errors, an' support accurate result reportin'.
Primary and secondary patient identifiersDate, time, and collector identificationTest orders, priority, and clinical notesLabel placement on glucose and CBC tubesElectronic vs paper requisitionsLegal and accreditation documentation needsLesson 9Patient Identification an' Pre-Test Needs (Fastin', Consent, Medication Review)Outline right patient ID an' pre-test prep fi glucose an' CBC, includin' fastin' check, consent, medication review, an' check of recent sickness or procedures weh may affect test understandin'.
