HIV Drug Resistance Training Module 2: The WHO Lab Network
Topics • Purpose and Goals of the WHO HIVDR Lab Network • Structure of the Network • Standards and Accreditation
Objectives • Describe the purpose and goals of the WHO laboratory network. • Describe the structure of the network. • Describe the role and responsibilities of specialized labs, regional labs, and national labs. • Describe the role of the DR working group.
purpose and goals of the who lab network Why is there a need for a lab network? What can we accomplish through a HIVDR network?
Why the Need for a Network? • Importance of preventing drug resistance • Importance of maintaining effectiveness of standard first-and second-line ART regimens
Why the Need for a Network? • Lack of common standards less reliable results • Shortage of lab infrastructure less access to testing • Cost and complexity of testing need for shared resources
Goals of the Network • Access to quality-assured, accredited genotyping lab services • Guidance for accurate collection, handling, shipment, storage, and testing of HIVDR specimens • Support and training
structure of the network What are the different types of labs in the network? What are the roles and responsibilities of specialized labs, regional labs, and national labs?
Laboratory Network Structure for HIV DR testing WHO Global Regional National National strategy for the collection, handling, storage, and shipment of HIVDR surveillance and monitoring specimens
How many NDRLs and Where? • In countries performing Surveillance and/or Monitoring Surveys • With approval of Ministry of Health • Where resources are available and not better spent elsewhere (e.g. drug supply, CD4, viral load labs) • If one genotyping lab is not enough to meet demand, or distance from collection sites too great, two or more labs may be needed
Discussion • Why is there a need for a lab network? • What can we accomplish through a HIVDR network? • What network labs are available to assist you? • What plans are in place for the future?
standards and accreditation What standards has WHO set for HIVDR labs in the network? How does a lab become accredited?
Standards • Specimen Types • Plasma • Serum • Dried fluid spots • Specimen Processing • Quality Assurance
Ministry of Health/National HIVDR committee designation National strategy for HIVDR prevention, surveillance and monitoring in place Minimal infrastructure for HIVDR genotyping Pass a WHO recognized Proficiency Panel Test within one year of assessment Accreditation for National HIVDR Laboratories: Mandatory Criteria
Minimal Infrastructure for HIVDR Genotyping • Separation of work areas, with workflow plan consistent with molecular diagnostic work • relevant anti-contamination laboratory spaces for PCR • Adequate equipment • Adequate laboratory and office space available and used efficiently • Electrical power backup • Reliable and well-documented specimen logistics and storage procedures and capacity • SOPs in place covering all aspects of laboratory procedures
Accreditation for National HIVDR Laboratories: Additional Criteria Each lab must attain a score of 85 points to be accredited
Continued WHO Accreditation Candidate lab Once only Accredited Not accredited Re-assessment (< 2 years) Approved Annual Re-assessment Not approved Only after consideration by advisory group Suspended
Discussion • What standards has WHO set for HIVDR labs in the network? • How does a lab become accredited?
Reflection • What do we need to do to get a national lab accredited—or will we use a regional lab?
