Dried Serum Spots for External Quality Assurance of Scrub Typhus <scp>IgM</scp> Serology: A Multicentre Pilot Study From India
Dried serum spots are a feasible, reliable and cost-effective alternative to conventional liquid serum for external quality assurance of O. tsutsugamushi IgM ELISA. The initial discordance observed underscores the importance of EQA in identifying procedural variability, while the final concordance confirms the robustness and suitability of DSS for EQA implementation in resource-limited, endemic settings like India.
