A new human pathogen triggering a pandemic can impact health directly through disease resulting from infection and indirectly through health system disruption. The COVID-19 pandemic is hypothesised to have impacted pathology testing by impacting healthcare and pathology operations and reducing healthcare attendance for fear of infection. The impacts of COVID-19 incidence and pandemic control measures on non-COVID pathology testing were assessed in four Australian states/territories using pathology data (histology, prostate-specific antigen, gynaecological cytology, complete blood count, haemoglobin A1c, and human immunodeficiency virus) from a large national private pathology provider (January 2019&ndash:December 2024). Weekly testing volumes from lockdown periods were compared to the equivalent weeks in 2019. All pathology tests demonstrated a substantial decline during the initial national lockdown in March 2020. Subsequent lockdowns were also associated with disruption. For example, complete blood count testing in Victoria was &minus:22% in March 2020 and &minus:5% in the second wave that year. Total annual testing volumes were lower for all tests in 2020 compared to 2019, excluding haemoglobin A1c, and reduced testing persisted through to 2024. The findings indicate substantial and sustained negative pandemic impacts on pathology testing. Reductions in pathology testing signal heightened risk of delayed disease diagnosis, disrupted chronic disease management, and poorer health outcomes.
