KAUST is implementing biweekly antigen testing to provide peace of mind for faculty and students working and studying in building 9. KAUST Health will conduct the testing and you will only be contacted if you have a positive result. The antigen test is a nasal swab, but much less invasive than a PCR nasal swab (it feels like blowing your nose). The swab will be administered on the first testing day by a health professional, and subsequently self-administered tests will be available.
