ABSTRACT
The COVID-19 pandemic led to the rapid development of tests to diagnose SARS-CoV-2 infection and ascertain the prevalence of infection, along with the formulation of various treatments and vaccines. Globally, over 220 anti-SARS-CoV-2 serological assays have been developed for laboratory use, and many of these assays are currently used to assess immune responses against SARS-CoV-2. However, because these assays were independently developed by different manufacturers with different target antigens, immunoglobulin detection, technologies, and data reporting approaches, the results are not directly comparable, making it challenging to draw conclusions regarding immune responses at the population level. With deficiencies in assay validation, standardisation, and harmonisation, the inability to use and compare large datasets is becoming a major issue as serological data continue to increase. To help in addressing this issue, WHO established the first International Standard for the anti-SARS-CoV-2 immunoglobulin in late 2020. In this Personal View, we define the WHO International Standard for the anti-SARS-CoV-2 immunoglobulin, summarise the uses of primary versus secondary serology standards, recommend the use of such standards for data harmonisation, and list guidance and resources for using serology standards to improve data comparability.
