All pre-procedural patients who warrant COVID-19 testing should be tested according to current guidelines. These guidelines apply to both vaccinated and unvaccinated patients. To prevent pre-surgical and pre-procedural patients from arriving for their procedure without having completed COVID-19 testing — and being subject to delays — they need to be tested within four days preceding their surgery or procedure. To avoid inconvenience for patients and obstacles to operational processes, please follow the standard recommendations for testing (PDF).
