6 Introduction Laboratory testing – integral part of patient care Medical assistant must knowCommon laboratory equipmentSafety in the laboratorySteps to prevent accidentsCLIA ’88 – impact on laboratory settingQuality assuranceQuality control proceduresRequired record-keeping
7 Role of Laboratory Testing in Patient Care Analysis of blood, urine, and other body fluidsRegular monitoring to identify diseases or other problemsConfirm initial diagnosisDetermine and monitor dosage of a medication
8 Role of Laboratory Testing (cont.) Kinds of laboratoriesReference laboratoryOwned and operated by an organization outside the practiceHave technological resources beyond the POLPOLQuicker turnaroundEliminates need for patient travel to other test locationSome managed care companies require their subscribers to use a specific reference laboratory.
9 Role of Laboratory Testing (cont.) Purpose of POLAccurate and timely processing of routine testsReporting test results to physicianTestsChemical analysisHematologic testsMicrobiologic testsUrinalysis
10 Super! Apply Your Knowledge Compare a reference laboratory and the POL.ANSWER: A reference laboratory is lab facility usually run by an organization separate from the practice. It has technologies beyond the POL. Patients have to travel to this facility. A POL provides quicker turnaround on results but is limited in the testing that can be performed. Patients are able to have testing done during an appointment without leaving the office.Super!
11 Medical Assistant’s Role Processing tests done in POLPreparing the patientCollecting the sampleCompleting the testReporting the resultsCommunicating information about the test
12 Medical Assistant’s Role (cont.) Additional responsibilitiesUnderstand regulationsAccident preventionWaste disposalHousekeeping and maintenanceQuality assurance and controlRecord-keepingInventory and order equipment and suppliesUse reference materialsScreen and follow-up results
13 Apply Your Knowledge Very Good! What are the duties of a medical assistant related to testing done in the POL?ANSWER: The medical assistant duties may include preparing the patient, collecting the sample, running the test, reporting the results, and, once the physician has reviewed the results, communicating the results to the patient.Very Good!
14 Use of Laboratory Equipment You may routinely use the following:AutoclaveCentrifugeMicroscopeElectronic equipmentEquipment used for measurement
15 Use of Laboratory Equipment (cont.) Autoclave - sterilizes surfaces of instruments and equipmentCentrifuge – spins and separates specimen into its component parts
16 Use of Laboratory Equipment (cont.) Optical microscopeUses light, concentrated through a condenser and focused through the object, to project an imageCompound microscope – two lenses magnify the image created by condensed light
17 Use of Laboratory Equipment: Microscope OcularsEyepiecesMonocularBinocularContain a magnifying lens – magnify image 10 times (10X lens)ObjectivesContain another magnifying lensMoved under ocular when neededThree objectivesTwo dryOne oil-immersionMicroscope
18 Use of Laboratory Equipment: Microscope (cont.) Arm and focus controlsArm – attaches oculars and objectives to bodyFocus controls – used to focus the objectLight sourceUnder stage and substageAdjustable intensityStage and substageStage – platform for slideSubstage – condenserSpecimen slides / coverslipMicroscope

20 Use of Laboratory Equipment (cont.) Using an optical microscopeOperate correctlyCare and maintenanceClean after each useStore under plastic coverMove by holding arm and supporting the base
21 Use of Laboratory Equipment (cont.) Electronic equipment and softwareUsed to create and maintain clinical dataMore accurate, safer, and more efficient than manual methodsPhotometer – measures light intensityEquipment used for measurementPipettesFlasks or beakersHemocytometerThermometers
22 Nice Job! Apply Your Knowledge Matching: ___ Measures light intensity A. Focus controls___ Platform for slide B. Hemocytometer___ Contains magnifying lens C. Stage___ One is an oil-immersion D. Photometer___ Condenser to concentrate light E. Ocular___ Move body tube up and down F. Substage___ Calibrated to count cells G. ObjectiveANSWER:DCEGNice Job!FAB
23 Safety in the Laboratory Primary concernOSHAProtection of employees in the workplaceSpecific guidelinesGeneral duty clauseIf no specific guidelinesWorkplace free from recognized hazardsEnforces guidelines from CDC
24 Safety in the Laboratory (cont.) OSHA guidelinesStandard PrecautionsHazard communication standardsOSHA Bloodborne Pathogens StandardHazardous Waste Operations and Emergency Response Final RuleNeedlestick Safety and Prevention Act
25 Safety in the Laboratory (cont.) Standard PrecautionsAssume that all blood, blood products, human tissue, and body fluids are contaminatedPPE guidelinesGlovesEye protectionUse equipment appropriatelyProper biohazard disposal

E XCLNT!ANSWER: MSDS must include:Name of the productChemical and common name of ingredientsChemical characteristics of the productsPhysical hazardsHealth hazardsGuidelines for safe handlingEmergency and first-aid procedures for exposure
33 Quality Assurance Programs Monitor the quality of patient careEnsure safety of workersAssess the quality of tests performedCLIARegulation of laboratoriesTest categoriesCertificate of WaiverModerate complexityHigh complexity
34 QA Programs: Certificate of Waiver Tests Pose insignificant risk to the patient if they are performed or interpreted incorrectlySimple and accurate, so the risk of obtaining incorrect results is minimalApproved by the FDA for home useOffice must apply for a Certificate of WaiverExempt from CLIA ’88 standardsMay be randomly inspected

42 Apply Your KnowledgeWhat is the purpose of a quality assurance program for a laboratory?ANSWER: The purpose of a QA program for a lab is to monitor the quality of patient care, ensure safety of workers, and assess the quality of tests performed.Quality Answer!
43 Communicating with the Patient Before testingPatient preparationVerification of patient preparationDuring specimen collectionProper patient identificationVerbal and nonverbalAfter specimen collectionPost-procedure instructionsSchedule for further testing, if needed
44 Communicating with the Patient (cont.) Test resultsReport to physician for interpretationReport to patient, if instructed to by the physicianPatient questionsAnswer if within your scopeRefer to physician
45 Record-Keeping Quality control and equipment maintenance Inventory controlRecord test results in patient recordsTracking of specimens
46 Record-Keeping (cont.) Patient recordsIdentify unusual findingsFollow office proceduresSpecimen identificationPatient informationPerson who collected specimenPhysicianPatient: Jason JonesDOB: 10/22/0000Date / time: 9:00 AMCollected by: shfPhysician: M. Welby
47 Apply Your Knowledge Bravo! Mr. Jones called for his laboratory results but the physician has not reviewed the results. What should the medical assistant do?ANSWER: The medical assistant should tell Mr. Jones that the physician has to review the results before releasing them to the patient. She should also tell Mr. Jones that she or the physician will call with the results once they are reviewed.When she reviews Mr. Jones’ laboratory results, she notes that his glucose is elevated. What should the medical assistant do?ANSWER: She should identify the test result that is out-of-range by circling or underlining it based on office policy.
48 In Summary Medical assistant and the POL Maintain and improve technical skillsKeep up on technological, legislative, and regulatory developmentsPrevent transmission of disease and occurrence of accidentsSeek ways to improve quality of patient carePerform tests efficiently and accuratelyMaintain equipment properly
