NRL EQAS are designed to assess the integrity of testing and meet the requirements of diagnostic and blood screening laboratories focused on quality testing.
NRL sets the standard for providing External Quality Assessment Schemes (EQAS) for Serology and Nucleic Acid Testing (NAT) for blood-borne and sexually transmitted infections. NRL’s comprehensive EQAS are designed to assess the integrity of a laboratory’s entire testing process by:
NRL EQAS Advantage

NRL EQAS are available for:
Participants receive panels of ten samples for serology EQAS, five samples for NAT EQAS and 15 samples for blood screening NAT EQAS. Where appropriate, the panels consist of a combination of positive and negative samples that would typically be received in a testing laboratory. They may also include low positive samples or samples of varying genotypes or subtypes to challenge assay sensitivity. Programmes include three panel distributions per year (excluding HIV-1 drug resistance and serology programmes supported by WHO, which have two panel distributions). Panels are shipped in accordance with IATA Dangerous Goods Regulations and include instructions stating that the samples should be processed according to normal procedures. Serology panels are transported at ambient temperature and NAT panels are transported on dry ice.
Participants report their results and information about the test run such as reagent batch used. On completion of testing, the data submitted online via an internet-based application called DigitalPT. Once the deadline date for reporting results has been reached, data are compiled in a final report. Data are statistically analysed to assist with inter-laboratory comparisons. The final report is distributed directly to participants using DigitalPT. The final report allows participants to compare their results with other participants using the same assays, identify any problems that may exist and receive suggestions as to how the source of the problems may be overcome.
