Rabies, a neglected zoonosis, claims approximately 60,000 lives globally each year. One of the significant challenges in rabies control efforts is the lack of surveillance data and underreporting, stemming from inadequate diagnostic facilities, particularly in low- and middle-income countries. At present, the World Health Organization recognizes the fluorescent antibody test (FAT) on postmortem brain specimens as the "gold standard" for confirming rabies in humans and animals. In this opinion article, we highlight several limitations of FAT and advocate for superior alternatives to replace it as the reference diagnostic technique for rabies. We argue that molecular techniques, specifically PCR-based methods, offer rapid, accurate, and convenient means of laboratory confirmation for rabies. Their implementation is now feasible due to the expanded technical and logistical capabilities achieved during the COVID-19 pandemic.
