EVALUATION OF RAPID Ag TEST KITS
Last updated: 19 May 2021
The Research Institute for Tropical Medicine (RITM), as the National Reference Laboratory, is mandated to perform the evaluation of commercially-manufactured in vitro diagnostic medical devices, in collaboration with the Philippine Food and Drug Administration (FDA).
In support of the national COVID-19 response, the Institute has undertaken evaluation of laboratory test kits (PCR, rapid antibody, rapid antigen kits), nucleic acid extraction kits, as well as virus transport media and swabs.

Performance evaluation involves comparison of the assay under evaluation and a reference assay. For Rapid Antigen test kit evaluation, the reference assay is RT-PCR.
The evaluation consists of fresh collection of nasopharyngeal swabs from cohorts of symptomatic and asymptomatic subjects, and testing these on the rapid antigen test being evaluated onsite. An additional nasopharygneal swab is taken and tested in parallel with RT-PCR. A minimum of 30 positives and 30 negatives are typically included per kit evaluated.
For Rapid Antigen Test Kits to be used in COVID-19 testing, the World Health Organization recommends a minimum sensitivity and specificity of 80% and 97%, respectively.
For Rapid Antigen Test Kits to be used in COVID-19 testing, HTAC recommends a minimum sensitivity and specificity of 80% and 97%, respectively. This standard metric is explained in depth in the Guidance Document on the Technical Requirements for SARS-COV-2 Rapid Antigen Tests published by HTAC in September 2020.
The Health Technology Assessment Council (HTAC) is an independent advisory body with the overall role of providing guidance to the Department of Health (DOH) and the Philippine Health Insurance Corporation (PhilHealth) on the coverage of health interventions and technologies to be funded by the government.
