WHO has published laboratory testing guidance for COVID19 in suspected human cases. Recognizing that the global spread of COVID-19 has dramatically increased the number of suspected cases and the geographic area where laboratory testing needed to be implemented, intensified COVID-19 molecular testing has led to shortages of molecular testing reagents globally for COVID-19 and for other molecular diagnostics. Beyond supply issues, there are significant limitations of absorption capacity in many regions, especially in low- and middle-income countries.
