DEPARTMENT OF HEALTH RESEARCH INSTITUTE FOR TROPICAL MEDICINE Laboratory Support and Biosafety in Specimen Handling in the Management of EVD Catherine B. Masangkay, M. D. Department of Pathology
Objectives: • To discuss the supportive POC diagnostic testing for patient management • To discuss the biosafety guidelines in the handling of specimens RESEARCH INSTITUTE FOR TROPICAL MEDICINE 2
Outline: I. Laboratory Support § § Recommended laboratory tests for clinical management of EVD cases Recommended testing platform for specimens from EVD cases II. Biosafety in Specimen Handling § § § Proper use of PPE Proper specimen handling during processing and testing Disinfection of the work area RESEARCH INSTITUTE FOR TROPICAL MEDICINE 3
What are the recommended laboratory tests? • RITM recommends use of solely POC (point of care) testing to minimize exposure • Patient Management Ø POC blood chemistry, hemoglobin, hematocrit Ø coagulation parameters (PT/INR) Ø electrolytes • Diagnostic Work-up Ø EVD confirmatory testing (RT-PCR, ELISA) Ø *Malaria thick blood film (trained microscopist) RESEARCH INSTITUTE FOR TROPICAL MEDICINE 4

What is the recommended laboratory set-up RESEARCH INSTITUTE FOR TROPICAL MEDICINE 9
Temporary “Point of Care” Laboratory • Specimens from PUIs/EVD Suspect Cases must not be processed and tested in the hospital’s general clinical laboratory. • A temporary “point of care” laboratory adjacent to or near the isolation rooms of PUIs/EVD suspect cases. • The temporary “point-of-care” laboratory shall have the following minimum required equipment: – Biosafety cabinet type II - calibrated and validated – Dedicated pipettors – Dedicated handheld Point-of-care testing system (e. g. , i-STAT or equivalent) – Autoclave • The temporary “point-of-care” laboratory shall have dedicated supplies and reagents for testing, specimen packaging and transport, spill management as well as waste management. RESEARCH INSTITUTE FOR TROPICAL MEDICINE 10
Biosafety in Specimen Handling
Personal Protective Equipment • All staff processing and performing routine diagnostic tests must wear the following appropriate personal protective equipment: – Attire under PPE: Scrub suit with dedicated washable footwear; No personal items (e. g. , cellphone, jewelry, etc. ) – Double layer of nitrile gloves with extended cuffs – Disposable Full face shield – Disposable coverall – N 95 respirator OR Powered Air Purifying Respirator (PAPR) – Fluid resistant or impermeable boots RESEARCH INSTITUTE FOR TROPICAL MEDICINE 12
BASIC REQUIREMENTS FOR ENSURING STAFF SAFETY IN SPECIMEN COLLECTION, HANDLING, PROCESSING AND TESTING OF SAMPLES FROM PUI’S AND EVD SUSPECT CASES SPECIMEN COLLECTOR LABORATORY PROCESSING AND TESTING PERSONNEL Minimum training and skill requirements: • Phlebotomy • Biosafety • Donning and doffing of Personal Protective Equipment Minimum training and skill requirements: - Good laboratory practices - Biosafety - Donning and doffing of Personal Protective Equipment - Use of Biosafety Cabinet - Use of Point-of. Care system (e. g. , i. STAT or equivalent) - Specimen packaging and shipment EQUIPMENT • Functional and certified Biosafety Cabinet Type II • Dedicated handheld point-of-care testing system (e. g. , i-STAT or equivalent) • Autoclave RESEARCH INSTITUTE FOR TROPICAL MEDICINE SUPPLIES AND REAGENTS • Supplies and reagents dedicated for routine testing of PUIs or EVD Suspect cases. • Supplies dedicated for waste management, such as sharps container, trash bags, trash bins, etc. 13
• Aerosol Generating Procedures • Limit activities that may generate aerosols to pipetting (POC) Decontamination of Patient’s Sample • All potentially contaminated liquid and solid materials should be appropriately sterilized before disposal. RESEARCH INSTITUTE FOR TROPICAL MEDICINE 14
Disinfection of Work Surfaces • Disinfection should be done promptly after completing work on the surface. • Work surfaces should be treated with a 1: 100 dilution of 5. 25% household bleach with contact time of at least 10 minutes. RESEARCH INSTITUTE FOR TROPICAL MEDICINE 15
